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.

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.



Allergic rhinitis

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.



How to Take Good Care of your Nose?

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.
