Andrew Moore asked:


Allergies are quite common today with practically everyone suffering from some form of allergy or the other. It is the overreaction of the immune system to antigens like bee stings, some food, insect stings or pollen that triggers an allergy. There are different types of allergic reactions that manifest itself in different ways in the body.

Allergies are generally mild with mild symptoms that go within a few days of getting rid of the trigger of the allergen. Occasionally, there are cases of people suffering from anaphylaxis which is a life threatening condition where there is difficulty in breathing and loss in consciousness.

One type of allergic reaction is seasonal allergic rhinitis, or hay fever. This is an allergic response to pollen and other microscopic substances that exist at certain times of the year. There are also conditions where allergic rhinitis works out to be perennial, or year round.

One of the types of allergic reactions is allergy to insect stings, which is very common. Some people however will not be aware of their allergy to insect stings until they are stung by an insect. More often than not, it is the second sting that triggers an allergy reaction while the first sting produces only a normal sting reaction. However if you have an allergy to insect stings, the severity of the reaction varies from person to person.

Allergy to latex is another of the types of allergic reactions where the person is allergic to substances made of natural latex. One of the main sources of this allergic reaction is rubber gloves while sometimes, latex that is used in other products like condoms and medical devices can trigger a reaction.

Mold allergy is an allergy that does not have a defined season as mold and fungi grow in all weather and thrive both indoors and outdoors. However some forms of outdoor mold tend to thrive in higher concentrations from spring to late fall. There are some people who suffer from allergy to cosmetics. With cosmetic allergy, you experience skin irritation because of some ingredients in the cosmetics like fragrances and preservatives. The two types of allergic reactions here are irritant contact dermatitis and allergic contact dermatitis.

Some people are allergic to pets; where it is not the pet’s feathers or fur that triggers a reaction. It is the invisible flakes of animal skin called dander that triggers sneezing, watery eyes and stuffy noses in some people. When you suffer from food allergies, it means that some food likes peanuts and jalapeños trigger an allergic reaction.

Symptoms here are like symptoms for different types of allergic reactions like hives, swelling of the throat and tongue, vomiting, abdominal cramps, diarrhea and a drop in blood pressure.

People suffering from allergic must know how to get first aid if it happens to them. Friend and family will be helpful if they know what it is. You will not know when it will be helpful.

Alexander Chong asked:


Allergic rhinitis is an atopic disease, which is inherited from the parent. If both your parents have allergic rhinitis or other respiratory diseases such as asthma, tuberculosis, and emphysema, the probability that you have these kinds of respiratory diseases is 50%. If one of your parents has respiratory diseases, the probability that you inherit their diseases is 25%. If both of your parents do not have any respiratory diseases, your chances to have respiratory diseases are no more than 12.5%. Sometimes, what has happened during pregnancy can cause allergic rhinitis to the newly born baby. The immunological status of the mother during pregnancy may cause the newly born baby has allergic rhinitis. Pregnant mothers who are smoking, drinking coffee and alcohol usually have poor immunological status, which can also cause newly born infant has allergic rhinitis or other respiratory diseases. This is because all these acts can cause high IgE antibody level in umbilical blood. Apart that, using bottle-feeding to feed milk to infant, early introduction of several kinds of food and early exposure to certain allergens and pollutants can cause nasal allergy to the newly born infant.



Allergic rhinitis symptoms change with age. At the earlier stage, children are mostly sensitive to seasonal allergens. After they have grown older, they usually become sensitive to perennial allergens. Therefore, after they have got over the symptom that is caused by seasonal allergens, they may still keep on the symptoms due to the perennial allergens. When the children grow older, they may have higher risk to have bronchial hyperreactivity and asthma. 17 to 19% of them will have asthma after grow up. To protect them from getting asthma, perennial immunotherapy should be used at the early stage. Moreover, the risk of getting asthma does not depend to age when the allergic rhinitis started, family history of atopic disease, sex, severity of symptoms at the starting period and treatment.

Allergic rhinitis started when the atopic individual meets the antigens that are able to stimulate the IgE response. So, what are substances that can act as allergens? Allergens usually are airborne particles, which have molecular weight ranging from 30 to 40,000 daltons and also with diameter ranging from 2 to 60 µm. Most of them have diameter more than 15 µm, which can deposit onto the nasal, pharyngeal and ocular surface. Chemically, these particles are proteins, which link to some small unit of carbohydrate. Particles that have these kinds of characters are pollen, acarids, animal dandruff and fungi.



Pollens that are released from grams, weeds and trees during breeding season usually cause seasonal allergic rhinitis. Only light pollens that can be pollinated by wind can exist in air and cause a high natural exposure to the allergic rhinitis patient. The seriousness depends to the concentration of the pollens in the atmosphere. Individual with allergic rhinitis who lives in suburban area will be seriously affected by these seasonal pollens compared to the one who lives in city. Surrounding temperature also gives an impact to the pollens concentration in air. Usually, in warmer environment, plants release more pollens compared to cold environment. Most of the plants breed in late spring and summer that is the warmest season. Windy weather will cause the pollens scatter around in air and this will cause the most exposure to the allergic rhinitis patient. The better day is rainy day. Rain water can wash all the pollens in air and bring them down to the ground. Surrounding air becomes fresher and cleaner after raining.



The main culprit of the perennial nasal allergy is house-dust mites. The acarids that are commonly found in the house dust are Dermatophagoides pteronyssimus and farinae, Euroglyphus maynei and Blomia tropicalis. Substances that are directly responsible to the nasal allergy from these dust mites are their body and metabolic products. Usually, mites grow rapidly in damp and warm climate. Therefore, sensitization to acarids depends to where you are actually living. Nasal allergy for patients who live in tropical and equatorial regions have higher possibility causes by acarids because these regions climate is promote mites growth. House-dust mites grow at maximized concentration when surrounding humidity level is between 70 to 80 % and with the presence of high temperature. Nasal allergy symptoms will develop when the level of dust mite concentration reaches 2 µg/g in air. Conversely, in high mountains with dry and cold climate have lowest level of dust mites because this climate prevents the mite growth. Animals also are the other source of aeroallergens. These aeroallergens are present in the animal’s saliva, feces, urine and dandruff. Therefore, nasal allergy can be caused by domestic animals such as cat and dog and also wild rats and mice.

Air pollutants enhance the sensitization of the nasal allergy by the allergens. Air pollutants can be divided to two groups that are outdoor pollutants, which are released from industrial works, automobile exhaust and domestic heating, and indoor pollutants such as tobacco smoke, furnishings, wood and coal burning and heater. Chemically, air pollutants consist of oxides of nitrogen, sulfur dioxide, ozone, carbon monoxide and black smoke. How actually air pollutants enhance sensitization of nasal allergy is not completely clear. This may be due to air pollutants easily irritate the respiratory mucosa and make it prone to allergic sensitization. Air pollutants have negative impact to the nasal epithelium and ciliary beat, which are responsible to the clearance of allergens. Furthermore, some pollutants can enhance the releasing of the mediators that induce inflammation such as histamine, prostaglandins and leukotriene C-4.

Apart from that, some pollutants also can stimulate synthesis of the IgE antibody directly. When allergen binds two IgE molecules together on the mast and basophil cells surface, primary chemical mediator; histamine, will be released and it will cause nasal allergy. Therefore, we can affirm that allergens can easily enter into our blood stream through our nasal mucosal membrane if we have chronic inflammation, not enough IgA antibody, impaired ciliary beat and also with air pollutants around us. IgA antibody is very important to our body because it prevents allergens from penetrating through our nasal mucosal layer. Monounsaturated oleic acids, which can be found in cold-pressed extra virgin olive and coconut oil, hazelnut or filbert oil (or the whole nuts), green and ripe olives, and almonds can increase IgA antibody in our body. Besides oleic acids, vitamin A also can increase IgA antibody, which can be found in cod liver oil, pumpkin, cooked carrots, sweet potatoes/yams, squash and other yellow or orange vegetable.

Alexander Chong asked:


What is actually allergy rhinitis? Allergy rhinitis is an allergic disease, which is caused by the sensitinogen that reacting on the mucous membranes in the nasal cavity. It has two types; those are perennial and seasonal allergic rhinitis. Perennial allergic rhinitis occurs throughout the year; whereas, seasonal allergic rhinitis usually occurs during the blossoming or flowering season. In this season, plants start to release their pollen for breeding purpose. Pollen is one of the sensitinogens to the allergic rhinitis. Clinical features of allergic rhinitis are; itching in the nose, sneezing, watery nasal discharge and nasal obstruction. There are about 20 % of adults and children have seasonal or perennial allergic rhinitis.

Although it is prevalence in most of the countries regardless tropical or seasonal, most of the conditions are not treated adequately and the consequence is that allergic rhinitis becomes chronic. The chronic state of allergic rhinitis usually will lead to more serious complications of the upper and lower airways such as asthma, sinusitis and otitis media with effusion. Otitis media is an inflammation of the middle ear. Fluid is built up in the middle ear and causes temporary lose of hearing. However, if this chronic disease is not treated properly, it may lead to permanent hearing impairment.

 A few medical scientists had carried out surveys to study the epidemiologic links between allergic rhinitis and other airway diseases. What they had found out were, 78% of patients who had asthma were also had allergic rhinitis. They also found out that 99% of adults and 93% of adolescents, who had allergic asthma, also had allergic rhinitis. Besides, the other study that had been carried out for 23 years was found out that college students who previously had allergic rhinitis had three times higher the possibility to have asthma compared to those students who had not had allergic rhinitis What is actually allergy rhinitis?

The chronic state of allergic rhinitis usually will lead to more serious complications of the upper and lower airways such as asthma, sinusitis and otitis media with effusion. Otitis media is an inflammation of the middle ear. Fluid is built up in the middle ear and causes temporary lose of hearing. However, if this chronic disease is not treated properly, it may lead to permanent hearing impairment.

A few medical scientists had carried out surveys to study the epidemiologic links between allergic rhinitis and other airway diseases. What they had found out were, 78% of patients who had asthma were also had allergic rhinitis. They also found out that 99% of adults and 93% of adolescents, who had allergic asthma, also had allergic rhinitis. Besides, the other study that had been carried out for 23 years was found out that college students who previously had allergic rhinitis had three times higher the possibility to have asthma compared to those students who had not had allergic rhinitis before.

Many researches and works had been carried out to study the epidemiologic link between allergic rhinitis and sinusitis. The results had been well documented. The earlier study showed that 53% of children, who had allergic rhinitis, also had sinusitis. They proved this from the children abnormal sinus radiographs. Whereas, recent study showed that up to 70% of children, who had allergy and chronic rhinitis, had abnormal sinus radiographs. 78% of the patients who had recurrent sinus infection, rhinitis allergy was coming together with their extensive sinus disease. For the children who had otitis media with effusion, 40 to 50% of them had allergic rhinitis. This was confirmed by positive allergy skin tests or increased serum IgE antibodies to specific allergens test.

Scientist had proposed a model for the development of sinusitis and otitis media. Their proposed model assumes that the earliest cause for sinusitis is not bacterial infection but it is due to the obstruction in the nasal cavity, which hinders the normal movement of air and secretions in and out of sinuses. Virus that causes nasal inflammation is upper respiratory tract infection (URTI) type, which is called rhinovirus. Research had been carried out to study the effect of this virus to the nasal diseases. The result showed that when rhinovirus is inoculated into the nasal passage of a group people, one third of these people would develop sinus abnormities and typical sinus disease symptoms. Another study also showed that 87% of healthy adult, who voluntarily went through self-diagnosed colds, had maxillary sinuses illness.

Fluid inside the sinus cavity must be drained normally to keep the nasal healthy. When nasal being infected by bacteria or virus, or exposure to allergen, dust or chemicals, thicken secretion will be developed and it has higher possibility blocks the narrowed sinus ostia (opening that connect to the sinus cavity). Accumulation of these secretions in the sinus cavity will lead to further obstruction, mucosal swelling and also thicken the sinus mucosa. This will create an anaerobic environment that further favorite the bacterial growth and lead to infection. Congested sinus ostia must be resolved if not, it will lead to recurrent acute and eventually chronic nasal disease. This model also explained why chronic sinusitis is resistant to the antimicrobials treatment alone. To treat the sinusitis properly, antihistamines and corticosteroids have to be used as a combination with the antimicrobials treatment.

A similar model had been developed by scientist to explain the occurrence of otitis media with effusion. 83% of the children had at least once occurrence of acute otits media by the time they reach 3 years old. This model hypothesizes that nasal inflammation that is caused by allergens or URTIs virus will further cause inflammatory swelling and obstruction of the Eustachian tube. Obstruction of the Eustachian tube will increase negative pressure in the middle area and without improper ventilation; fluids will accumulate in the middle ear. Obstructed Eustachian tube will open occasionally with an effusion and this will **** the inner nasal secretion, which contain bacteria, virus and allergens into the middle ear cavity. Consequently, this will cause acute bacterial otitis media.

From the information above that have been gathered from various scientific publications, we know that common nasal allergy should not be left untreated. This is because it will lead to obstruction, fluid accumulation, bacterial infection and acute disease. If these diseases are not treated properly or successfully, a chronic state of inflammation, nasal congestion, and sinus infection will be developed. And it can further cause mucosal damage and ultimately, chronic disease. If the disease spreads to the middle ear, it will cause permanent hearing impairment

 

Abhishek Agarwal asked:


Millions of Americans suffer from one respiratory disorder or the other, which can impact their lives in serious ways. A respiratory disorder can be acute or chronic. Acute disorders can be easily treated and last for a short time. On the other hand, chronic disorders are not only difficult to treat but can also leave a person disabled for life.

What is Allergic Bronchitis?

Allergic bronchitis is a type of respiratory disorder. It is commonly referred to as allergic asthma. The immune system of a person suffering from allergic bronchitis is highly sensitve and so hyperactive that it attacks even hamless foriegn substance that enter the body. To put it in other words, the immune system labels a harmless entrant into the body as “dangerous” and produces antibodies to fight against it.

In allergic bronchitis, irritants and allergens inflame the bronchi and lower parts of the respiratory system. The condition lasts as long as the person is exposed to the allergens. In addition, allergic bronchitis is closely associated with asthma and respiratory allergy and can lead to conditions such as hay fever and allergic rhinitis.

In most cases, allergic bronchitis causes mild to moderate suffering. However, it is important to realize that allergic bronchitis can become very dangerous and even cause death. This is because some people are extremely sensitive to allergens. This extreme sensitivity can lead to suffocation caused due to the blocking of airways by inflamed tissues. People in this condition are in great danger. They need immediate hospitalization and medical care.

You know you are a victim of allergic bronchitis when you suffer from breathlessness, runny nose, red or swollen eyes, hyperventilation, tight chest, tickling in throat, persistent sneezing or coughing, headache, nausea, and so on. As soon as you recognise these symptoms, seek the help of a medical practitioner.

Treatment of Allergic Bronchitis

The importance of consulting a physician as soon you notice symptoms of allergic bronchitis cannot be overstressed. The doctor will conduct the required steps to find out which type of allergen is responsible for your particular problem. The test involves injecting an allergen directly under the skin and observing the way your body reacts to it.

Your doctor might even ask you to see an allergist. Allergists perform a series of tests in order to understand the nature of your allergy to a particular allergen. In addition, allergists can also teach you how to prevent the relapse of allergic bronchitis.

Treating mild or moderate allergic bronchitis is fairly simple. You need plenty of knowledge about the disorder, and you also need to know the particular type of allergen responsible for your problem. Once you know, it is easy to just avoid the allergens responsible for your problem. The medical treatment for this condition is anti-histamine medication.

Prevention of Allergic Bronchitis

It is easy to manage and even prevent allergic bronchitis. As mentioned previously, the easiest way is to determine the particular allergen causing your problem and just stay away from it. In addition to this, it pays to know a few things such as the following.

The summer season can aggravate this condition simply because during the summer, there are plenty of allergens in the air.

Remember to bathe your pets regularly and free their fur from any allergens. A lot of allergens are frequently found in the fur of animals.

Take special care of yourself if you are suffering from allergic bronchitis. As already said, the condition can get dangerous.

Keep some anit-histamine medication with you while travelling. You never know the type of allergens you might come across in an unfamiliar location. Having some anti-histamine with you will help you easily control any allergic reaction that might come up.

Be assured that it is possible to live a full, happy, and productive life even with allergic bronchitis. It is very important to keep yourself informed about your condition, ways of treating it, and way of preventing it. Be in touch with your allergist and your doctor. They are the best people to give you all the information you require about allergic bronchitis and to teach you how to live with the problem effectively.

Juliet Cohen asked:


Nasal polyps are the most common tumors of the nasal cavity. Nasal polyposis can impair a person’s quality of life more than perennial allergic rhinitis. Nasal polyps are soft, jelly-like overgrowths of the lining of the sinuses. They look like grapes on the end of a stalk. Large polyps can bloc the nose and increase the risk of sinusitis. They may be yellowish, grey or pink in colour. They are common and are not cancerous. Nasal polyposis results from chronic inflammation of the nasal and sinus mucous membranes. Chronic inflammation causes a reactive hyperplasia of the intranasal mucosal membrane, which results in the formation of polyps.

Nasal polyps can vary significantly in size. There may be only one but sometimes several develop like a ’small bunch of grapes’ on a stem. Polyps usually affect both nostrils. Nasal polyps can vary greatly in size. There may be only one but sometimes several grow like a ’small bunch of grapes’ on a stem. The cause of the inflammation is certain conditions make nose inflammation and polyps more likely. These include: asthma, allergy to aspirin, cystic fibrosis, and some rare conditions of the nose. Nasal polyps can occur along with many other respiratory diseases, such as allergic rhinitis, chronic sinusitis, asthma, and aspirin allergy.

Nasal polyps also occur in a majority of people with Churg-Strauss syndrome, a rare disease that inflames the blood vessels (vasculitis). Nasal polyps occur in around 1 in 200 people. It appears that nasal polyps are more common in people with non-allergic rhinitis and non-allergic asthma, rather than allergic types of these conditions. Nasal polyps can affect anyone. However, most cases occur in people over the age of 40 years. They are four times more common in men than in women. In general, women are more likely to have nasal polyps than are men. Nasal polyps are uncommon in children.

Medications are the most common treatment for nasal polyps. Surgery may be needed to eliminate larger growths. Topical nasal steroid sprays, such as Flonase and Nasonex, can help decrease the size of nasal polyps and prevent polyps from growing back after surgery. Use allergy shots in an attempt to treat or stop nasal polyps from growing back after surgery. Intranasal corticosteroid sprays reduce the growth of small intranasal polyps are most effective in the postoperative period. Prevention is better than cure. Avoid over-the-counter saline sprays that contain additives, such as benzalkonium, which can actually inflame the mucous lining of your nose.

Cindy Heller asked:


Most everyone has an idea of what an allergy is. Allergies are so common, in fact, that it seems acceptable to discuss allergy symptoms at a cocktail party with perfect strangers.

An allergy is an abnormal reaction by a person’s immune system to a normally harmless substance. A person without allergies would have no reaction to this substance, but when a person who is allergic encounters the trigger, the body reacts by releasing chemicals which cause allergy symptoms.

In children, allergic disease first occurs as atopic dermatitis (eczema) or food allergies. Children with atopic dermatitis are then at an increased risk of developing allergic rhinitis and asthma; both are more likely to occur in school-age children.

Typically, atopic dermatitis goes away by adulthood, as do many types of food allergies.

Allergic rhinitis and asthma, however, most often start during the adolescent, teenage and young adult years, and are likely to persist throughout a person’s life. The severity of allergic symptoms, however, may wax and wane, and even temporarily disappear during a person’s life.

Atopic Dermatitis

This is typically the first sign of allergies and is seen in 10 to 20% of all children, frequently during infancy. Atopic dermatitis, or eczema, is characterized by itching, with rash formation at the sites of scratching. The rash is typically red and dry, may have small blisters, and can flake and ooze over time.

In infants and very young children, this rash involves the face (especially the cheeks), chest and trunk, back of the scalp and may involve the arms and legs. This distribution reflects where the child is able to scratch, and therefore usually spares the diaper area. The location of the rash changes in older children and adults to classically involve the skin in front of the elbows and behind the knees. Food and environmental allergies have been shown to worsen atopic dermatitis.

Food Allergies

Food allergies can occur at any age. Almost all people with food allergies will have a skin symptom, such as hives, swelling, itching or redness of the skin, as a result of eating the culprit food. These symptoms typically occur within a few minutes of eating the food in question, although they can be delayed up to a couple of hours.

Other symptoms of food allergies can include nausea, vomiting, stomach aches, diarrhea, breathing difficulties (asthma symptoms), runny nose, sneezing, and lightheadedness. In some cases, children can experience a severe allergic reaction, called anaphylaxis, which can be life-threatening.

Nasal Allergies

Allergic rhinitis occurs in up to 30% of adults and up to 40% of children. Symptoms of allergic rhinitis include sneezing, runny nose, itchy nose and eyes and nasal congestion. Some people may also experience post-nasal drip, allergic shiners (dark circles under the eyes), and a line across the nasal bridge from an upward rubbing of the palm of the hand on the nose, a sign called the “allergic salute.”

Asthma

Allergies are a major cause of asthma, a condition that occurs in about 8% of all people. Though it can occur at any age, it is most often seen in males in the pre-teen years and in females in the teenage years; asthma is the most common chronic disease in children and young adults. Sometimes asthma is difficult to diagnose in very young children, and may require a physician who is an asthma specialist.

Symptoms of asthma may include:

- Coughing — This can be the only symptom in some people who have “cough-variant asthma.” The cough is often dry, hacking, and may be worse with allergic triggers and after exercise. The cough may only be present at night. Cold air may also trigger this symptom.

- Wheezing — This is a high-pitched, musical-like sound that can occur with breathing in and out in people with asthma. Wheezing usually occurs along with other asthma symptoms, may get worse with exercise and with allergic triggers.

- Shortness of breath — Most people with asthma feel as if they’re not getting enough air at times, particularly when they are physically exerting themselves or when an allergic trigger is present. People with more severe asthma have shortness of breath at rest or wake-up with this symptom during the night.

- Chest tightness — Some people describe this as a sensation that someone is squeezing or hugging them. Children may say that their chest hurts or feels “funny.”

Many asthmatics have symptoms with exercise; this does not necessarily mean that their asthma is severe or uncontrolled.

Neelima Reddy asked:


Itchiness, watery eyes, runny nose, sneezing, and redness are some of the common symptoms that majority of the people experiences as allergy symptoms.

The most effective way to fight against particular allergen is immunotherapy or allergy shot, but some people will get frightened to get allergy shot.

Allergy shots hold a little amount of substance that fights against the particular allergen. For example, if the person is allergic to pollen, a small amount of substance called pollen will be added to the shot.

A small amount will be given so that the body will get used to fight against the allergen and if the body comes in contact with that substance next time, body will be familiar with that.

Who are not eligible to take allergy shot?

Allergy shots are not safe for everyone. Although most of the people experienced positive results from these shots, they are not suitable for all. People who are suffering from asthma, heart attack, and respiratory problems, pregnant women, and children under age of five are not recommended to receive allergy shot.

Alternatively, certain individuals are experiencing some side effects such as:

• Feelings of shock when the shot is initially injected

• Lightheadedness

• Nausea

So, for these reasons, the patient should stay in the doctor’s office for at least fifteen to twenty minutes after receiving the shot.

Benefits of allergy shots:

• Allergy shots improve allergic rhinitis, hay fever, bee sting allergies, drug allergies, and eye allergies.

• In some cases, allergy shots improve asthma symptoms also. The most common reaction to allergy shot is swelling at the place where the shot is given.

The success of this immunotherapy varies from person to person depending on the severity of the person’s allergy and the number of substances the person is allergic to.

In addition to the traditional allergy shots, there are new approaches to immunotherapy procedures to treat allergies.

Oral immunotherapy works similar to the allergy shot. In this method, increasing doses of allergen will be given to slowly build up the patient’s tolerance. The only difference with oral immunotherapy from allergy shot is with oral immunotherapy extract of allergen is used as drops. In this method, generally the drops are placed under the tongue and then swallowed.

Intranasal immunotherapy method involves intranasal administration of grass and house dust mite allergen extracts, which reduces the nasal symptoms such as “nasal allergy”.

The side effect with intranasal immunotherapy is nasal irritation. When compared to the traditional allergy shots, intranasal immunotherapy has no long lasting benefits.

Rush immunotherapy involves quick build up to the maintenance dose of extract. In this method of treatment, during early phase increasing doses of allergen will be given every few hours rather than a few days. Since there is a great risk involved with this rush immunotherapy, this should be done in hospital under close supervision.

Some people will experience severe reaction to the allergy shot, which is called “anaphylaxis”. In case of bad reaction with this shot, physicians will do appropriate treatment to stop this reaction.

Since allergy shots are not good for everyone, talking to the physician before taking this shot is more advisable. Visit Allergy Symptoms

Sajid Latif asked:


What is allergic rhinitis?

Allergic rhinitis is inflammation of the nose resulting from an allergy. It affects five to 10 per cent of the population. A very common form is hay fever.

What causes allergic rhinitis and what are the risk factors?

An allergy is a response by the body’s defence system (the immune system) to something that is not a harmful infection. Such ‘harmless’ substances (allergens) include pollen, cat hair, animal dander, the house dust mite and mould spores.

It is not known why people develop allergic rhinitis. It is more common in people from families with eczema and asthma and there is probably an inherited factor that affects the way the immune system reacts to allergens.

What are the symptoms and complications of allergic rhinitis?

Allergic rhinitis results in a runny, itchy and blocked nose. On lying down at night the fluid in the nose drips down on to the back of the throat and causes bouts of coughing, which can be uncomfortable and disturb sleep.

How do doctors recognise allergic rhinitis?

Allergic rhinitis is usually diagnosed on the basis of the symptoms and their seasonal nature if it is hay fever or their association with a particular allergen such as cat hair.

Year-round allergic rhinitis due to mould spores or house dust mite is more difficult to diagnose as there are other similar forms of rhinitis that do not result from allergy. More than one allergen may be involved

What is the treatment for allergic rhinitis?

Self-care action plan

A self-care action plans to avoid the allergen and so minimise the symptoms of allergic rhinitis includes:

Keeping windows closed and using an air ioniser (for pollen)

Regular vacuuming using a vacuum cleaner with a pollen filter (all allergens)

Damp dusting, so preventing dust from being dispersed into the air (for house dust mite)

Use of special bed and pillow coverings and regular laundering of bedclothes

Medicines

A variety of medicines can be bought at the chemist to treat allergic rhinitis. Probably the most effective is a beclomethasone nasal spray. This acts to stop the inflammation in the nose, but takes a few days to produce this effect and so needs to be started before the symptoms become too severe. Once the symptoms are severe it may be sneezed straight out again.

Although allergic rhinitis is common in young women, none of these medications is recommended for use during pregnancy. All should be avoided if possible during pregnancy and increased efforts should be made to minimise exposure to the allergen as outlined in the self-care section of this factsheet. If the symptoms remain a problem, a doctor should be consulted.

Hyposensitisation

This involves giving gradually increasing doses of the substance that causes the allergy and in the process making the immune system less responsive to it. This should only be carried out under close medical supervision as occasionally this treatment causes a life-threatening allergic response that must be treated immediately with an injection of adrenaline.

Complementary therapy

Some complementary therapies (homoeopathy, osteopathy and acupuncture) claim to have beneficial effects on hay fever, but the explanations for their effect are not consistent with the traditional medical understanding of hay fever. Shiatsu, the Alexander technique and aromatherapy may help to improve general well-being and symptoms.

Alexander Chong asked:


A patient once had asked to a doctor about what did he need to do to take good care of his nose. The doctor simply and straightforwardly replied to the patient that what was more important was what not to do to your nose. Bad habits such as nose-picking, sniffing, rubbing, blowing the noses hard or stuffing things such as tissue and handkerchiefs up to the nostril can do a lot of harm to your nose. Generally, nose will take good care by itself. Physiologically, when we breathe in air in our lung, nose will warm, clean and humidify it. When we breathe out the air from our lung, it will cool and remove the water from the air. Besides using for breathing, nose is also the organ of smell and allows us to speech with a quality voice. Anatomically, a layer of skin covers the external part of the nose. Appearance of the nose is maintained by a complex network of bone and cartilage. Its function and shape may be altered if its complex network of bone and cartilage has been damaged by either trauma or infection.

Internal part of the nose contains respiratory mucous membranes, paranasal sinuses, nasolacrimal duct and nasopharynx. Besides all these sinuses, internal part of the nose also contains gland that secreting mucous. Tiny-hair-like-cilia continuously pushes the secreted mucous backwards into the back of our nose and throat, in order that, mucus does not flow out from our nostrils. Septum is the partition in the middle part of the internal nose. It is a cartilage, which can be easily fractured. Some people septum has deviated after born and some deviation may due to the unperceived injury during childhood. This will cause blockage on one side of the nose. However, this deviation can be corrected by an operation.

Contents of mucus are merely a mixture of water, ions, glycoproteins and immunoglobulins. Mucus can be said as part of the nasal defense system and it keeps the nose clean and free from bacteria, fungus and viruses. At the roof of the nose, there is olfactory mucosa, which is responsible for our sense of smell. Located at the side and top of the nasal cavity are the air sacs paranasal sinuses. There are total four pairs of paranasal sinuses and given name as maxillary, ethmoid, frontal and sphenoid sinuses. This is where the mucous has been produced and being drained out through the openings called ostium. Infection that causes obstruction to this mucous outflow can lead to sinusitis. Conditions that directly and indirectly affect the nose are common colds, allergic rhinitis, sinusitis and nasal polyps.

Common cold is a very common disease that everybody can suffer at one time or another. It is caused by an infection of self-limiting viral. The symptoms are production of excessive clear mucous (runny nose), sneezing and nasal congestion. Seriousness of this disease is depending to how strong our immune system and also how vigorous the viruses that attack us. If we have a strong immune system, this disease will not exacerbate to sinusitis, asthma and Otitis Media with Effusion (OME). People with weak immune system will suffer a lot more. This is because it not only causes runny nose but also causes inflammation in the nasal passages and sore throat. If this disease does not treat within a few days for the one who does not have a strong immune system, it can exacerbate to sinusitis, asthma and Otitis Media with Effusion (OME). This disease can easily spread through body to body close contact especially hand to hand contact, sneezing mucous and saliva droplets. To recover from this disease, infected person only needs to keep warm, rest and take a lot of warm water. According to most of the resources, there is no cure for common cold. However, doctor usually prescribes antibiotic, anti-fever drug and anti-cough syrup to the patience. Most of the medical doctor will also include a few supplements such as vitamin C, zinc and Echinacea. Prescribed antibiotic by the doctor is not for treating the common cold virus. This is because antibiotic is not capable to kill virus. However, it can kill bacteria that take advantage during the infection of cold viruses.

Allergic rhinitis is also known as sensitive nose. Symptoms of this disease are continuous sneezing, nasal congestion and runny nose. The symptoms emerge only when one has been exposed to certain allergens such as house dust-mite, pollen, fungi, cigarette smoke, animal dandruff, furs and other irritating volatile chemicals. Sufferer can take anti-histamine tablets to relieve from this disease. Histamine is the main chemical that causes sensitive feeling in the nasal cavity. Nasal sprays contains corticosteroid hormone, which helps reduce our body immune system sensitivity to the foreign antigen, also can help to relieve the sensitive feeling in the nasal cavity. Corticosteroid is one of hormone that has been secreted from our adrenalin gland. Besides all these, immunotherapy is also one of the ways that can be used to treat this disease. These symptoms also can be alleviated by having regular exercise

Sinusitis is caused by the infection of the bacteria and fungi to the paranasal sinuses. This happens when bacteria and fungi entering these cavities. Occurrence of sinusitis is due to inflammation, nasal polyps and other nasal anatomical abnormalities that obstruct the mucosal outflow. Patient with sinusitis usually feels pain or pressure at the forehead or face. It is quite common that yellowish and greenish mucous will be discharged from your nostril especially in the morning. One with sinusitis, sense of smell will reduce or not that sharp compared to healthy nose. Sinusitis is due to the bacteria and fungi infection, so, antibiotics can help. However, prolonged and frequent sufferers may need to go through operation to clean up the nasal sinuses.

Nasal polyps are a grape-like swellings found in nasal cavity. They tend to block the air to flow through the nasal passage when breathing. Usually, it will cause production of excessive mucous. Sometimes, it will obstruct the ostium of the paranasal sinuses and cause the nasal mucous cannot be flowed out easily from the paranasal sinuses. This will give rise to sinusitis. Nasal sprays can control nasal polyps. Some nasal sprays can make the nasal polyps shrank temporarily. However, prolonged use will cause the nasal polyps rebound and become bigger. But if the nasal polyps are big and multiple and cause obstruction in the nasal cavity, operation is required to remove them. Unfortunately, they are a recurring disease.
