bronchial asthma and allergyAllergy is a sharp reaction of the body’s immune system to usually harmless substances. Symptoms of allergy can occur in different parts of the body, lasting from a few minutes to several days and be different in severity. Let’s learn about the disease nature and treatment methods together with Canadian Health&Care Mall.

There may be allergy for hair of some animal species, a variety of products, dust, medicines, chemicals, insect bites and pollen. Substances that cause an allergy, are called allergens. In some cases, allergic reactions are so weak that you can not even be aware that you generally suffer from allergies.

But allergies can bу also extremely dangerous and even life threatening. People suffering from allergies, may get anaphylactic shock – a severe pathological condition associated with an extremely sharp reaction to the allergen. Anaphylaxis can be caused by various allergens: drugs, insect bites, food. Also, anaphylactic shock can happen due to skin contact with an allergen, such as latex.

A food allergy is an immune reaction caused by certain foods and accompanied by well-known symptoms. A food allergy occurs when the body mistakenly take a certain product for a threat to the body and makes the immune system produce antibodies for self-defense. In case of readmission of the allergen, the immune system quickly “learns” this material and reacts immediately by producing antibodies again. These substances cause allergic symptoms. Food allergy often develops in this way.

In some cases, adults get rid of allergies observed in childhood. But if the allergy manifested itself only in adulthood, it’s very difficult get rid of it. Allergic rhinitis is observed in 1 case of 10 and is often hereditary. People with other allergic diseases, such as asthma or eczema also often suffer from allergic rhinitis. Such allergies are more common for women than for men. In case of allergic rhinitis we may observe following symptoms: itchy eyes, throat, nose and on the palate, sneezing, and stuffy nose, watery eyes, mucous discharge from the nose, conjunctivitis (redness and pain in the eyes). In severe cases of allergic rhinitis there may happen an asthma attack (especially people suffering from asthma) and / or eczema.

The physician must eliminate the possibility of other diseases and conduct tests for the identification of the allergen and prescribe antihistamines and, if necessary, steroids. If the allergen is identified, but the contact with it is inevitable, the physician should introduce a special vaccine for the prevention and treatment of allergies.

Also, the doctor may recommend a special diet for patients suffering from food allergy.
