Allergic rhinitis, more commonly known as “hay fever,” happens when you breathe in something you are allergic to. The inside of your nose becomes inflamed or swollen.

When this happens, the body’s immune system overreacts to specific particles such as plant pollens, molds, dust mites, animal hair, industrial chemicals, tobacco smoke, foods, medicines, and even insect venom.

Allergic rhinitis affects 40 million people in the United States and is an extremely common condition, affecting approximately 20% of the population. While allergic rhinitis is not a life-threatening condition, complications can occur and the condition can impair one’s quality of life leading to a number of indirect costs. Recently, the total direct and indirect cost of allergic rhinitis was estimated at around $5 billion annually.

What are the symptoms of allergic rhinitis?

Signs of allergic rhinitis are similar to signs of a common cold. But, unlike symptoms for the common cold, allergic rhinitis can last for more than 8-10 days. Symptoms include: -stuffy or runny nose -sneezing -itchy or watery nose -itchy or watery eyes -coughing (caused by clear mucus running down the back of the throat) -feeling of a ‘permanent cold’ that never goes away -headaches and earache -constant sore throats and postnasal drip -sleep disturbances and snoring -loss of taste and smell -poor concentration

Children who have allergic rhinitis might have dark circles under their eyes known as Allergic shiners” (related to nasal congestion). They may also use either the palm or the back of their hand to push their nose up as they try to stop the itching (called the “allergic salute”).

What causes allergic rhinitis?

Like our previous discussion, allergic rhinitis is caused by substances that trigger allergies, called allergens. These allergens are found both indoors and outdoors. When allergic rhinitis is caused by common outdoor allergens, like mold or trees, grass and weed pollens, it is often referred to as seasonal allergies, or “hay fever.”

Allergic rhinitis may also be triggered by allergens found in your house like animal dander (tiny skin flakes and saliva), indoor mold, and cockroach or house dust mite droppings.

If you experience symptoms during spring, you may be allergic to tree pollens which we will discuss in detail further on.

To know for certain what causes your symptoms, an allergist or immunologist can perform skin tests to determine what you are allergic to.

What are my choices or treatment?

Over-the-counter antihistamines and nose sprays can help at first, but they can have a number of unpleasant side effects. These antihistamines can make you feel tired and drowsy while nasal sprays can make your stuffiness worse.

Doctor-prescribed nose sprays and antihistamines are different types of medication and are very helpful for controlling long-term symptoms. Some are safe for young children and all are safe for adults.

Consultation with an allergist will determine the medicine and treatment that is right for you.

Can I do anything to avoid getting allergic rhinitis? As prevention is worth a pound of cure, there are some things you can do in your house that might make your symptoms better if not avoid them altogether:

For those who have rhinitis, it may be best not to have pets. But if it cannot be helped, make sure to wash your pet (especially if hairy and furry) once a week. Keeping them out of the bedroom and off the furniture will help as well.

Put pillows and mattresses in sealed plastic covers that keep out dust mites, and wash sheets in hot water weekly. Washing machines at the local Laundromat will have hot enough water to kill the dust mites.

Keep windows closed. If possible, get an air conditioner and run a dehumidifier, so that there will not be so many pollens and molds getting in the house.

What are allergy shots?

For some patients, allergy shots, also known as immunotherapy, are very helpful, and safe. Allergy shots help how your body handles allergens by injecting into your body small amounts of the substances causing your allergy. Over the period of the therapy, your body will learn to accept the allergen without overreacting to it (which is the reason for the allergic reactions).

Your doctor may talk to you about allergy shots if your allergy symptoms are very bad and if they happen for most of the year. You can also consider this if you are constantly around the allergens (such as pollens and dust mites) and if in spite medicines, you are still symptomatic.



All About Hay Fever

The medical term for hay fever is allergic rhinitis. It is very similar to asthma except for one important difference. If you have asthma, airborne particles cause an allergic reaction in your chest and lungs. If you have hay fever you experience this reaction in your eyes, nose, and throat.

The airborne irritant is called an allergen. When you are exposed to the allergen your body releases a chemical called histamine. This results in an inflammation in your sinuses, the fragile lining of your nasal passages, your eyelids and the surface layer of your eyes. Common allergens that trigger hay fever are dust mites, pollen, animal skin and hair, and feathers.

There are two types of hay fever, seasonal and perennial. If pollen is the only allergen that triggers your hay fever, you have seasonal allergic rhinitis, as pollen is not present in the air all year long. Your symptoms will only appear when you are in an area where plants produce pollen at the time of year when this happens. However if your hay fever is triggered by dust mites, animal hair or feathers, it would be perennial as these airborne particles are present year round. It is also possible to have both perennial and seasonal allergic rhinitis if more than one allergen triggers your symptoms. People with allergic rhinitis will start to sneeze, develop a runny nose and red watery eyes whenever they are exposed to the allergen that triggers their attacks. The eyes also itch and rubbing them makes it worse. Sometimes the skin itches and the throat becomes dry. Wheezing also occurs. An allergy attack will be most severe for fifteen to thirty minutes. Most people are aware when they are allergic to pollen. However, they may not know what other allergens they react to. If this is a problem, physicians can perform skin tests to identify the allergens that trigger the attacks.

Once you know the substances you are allergic to, try to minimize your exposure to these irritants or avoid them altogether. There are many over the counter preparations designed to help hay fever sufferers. The most common are antihistamines. These can both prevent and stop an attack however they may need to be used for several days. Antihistamines have certain side effects such as dryness in the nose and throat and drowsiness. A person taking antihistamines should exercise caution about driving or operating machinery until they know how the medicine affects them. If over the counter medications are not effective, there are prescription medications available from a physician. Antihistamines only relieve the symptoms of hay fever. They do not cure it. However, if you have had a skin test and your doctor has identified the substance that triggers your attacks, it is possible to cure the underlying cause. The doctor can administer a series of desensitizing injections. These actually contain the allergen and are given in increasingly stronger doses to stop reactions. While they have been successful with some patients, they do not work for everyone.
