Causative Factors and Treatment Of Allergy

Allergy is nothing but an exaggerated response of immune system to certain allergens. When a foreign substance comes in contact with the body’s immune system, the inflammation and irritation set in due to excessive production of a chemical, histamine. However, in a healthy person with strong immunity, the foreign substance may not create any problem. People with weak and oversensitive immune system are more susceptible to allergic reactions; therefore, children, young adults and elderly people are vulnerable.

Allergy occurs in any part of the body, but most commonly seen in respiratory tract and skin. One may also suffer from an anaphylactic shock, a type of hypertensive allergic reaction, in which a person needs hospitalization. Allergic rhinitis (hay fever) and urticaria (nettle rash) are the common types of allergies. The causative factors of these health issues are somewhat similar, but the signs and symptoms vary.

Causative factors of allergy –

As said earlier, an allergen is responsible for an allergic reaction, which interacts with the exaggerated immune system. The allergens causing an allergic response are:

 • Dust/Dust mites

 • Viruses

 • Plant pollens

 • Flowers

 • Perfumes

 • Animal dander

 • Molds

 • Environmental pollutants

 • Sudden climactic changes

 • Certain foods

 • Certain medications

The signs and symptoms of allergy –

In allergic rhinitis, the inflammation of airways produces symptoms of upper respiratory tract, such as constant sneezing, cough, runny/stuffy nose, nasal congestion, mild fever, red/itchy eyes, headache and temporary loss of smell and taste. In urticaria, the skin develops small rashes with burning, redness and itching. In severe case of allergic reaction, one may experience puffiness in face, lips and tongue.

How to treat allergies?

Many aspects come in to play while managing an allergic reaction. The first things is to avoid the allergen from entering the body. This can be done by covering the nose with a protective mask whenever you are supposed to go outside in an extremely cold climate. Try to avoid those foods that are allergic to your body. Simultaneously, one may require an oral medication to overcome an allergic response. If you fail to manage your allergy even after taking medications and following preventive measures, you may require immunotherapy, which is to be taken under the supervision of the doctor.

The conventional medications used to treat allergy are easily available as most of them are over-the-counter (OTC) drugs. The main action of the medications is on histamine, which means they dramatically cease the secretion of histamine in order to bring down allergic response and symptoms. Some of the commonly used antihistamines are:

 • Generic Allegra (Fexofenadine)

 • Generic Claritin (Loratadine)

 • Generic Zyrtec (Cetirizine)

 • Xyzal (Levocetrizine)
