The immune system, which protects our body from diseases, may also react against substances that are not normally harmful in some people. In atopic, that is, "allergic body", IgE type antibodies are formed against allergens as a result of repetitive encounters of the immune system with allergens.This process is called "sensitization". After the sensitization process is completed, after each contact with the allergen, signs of allergic disease occur in a short time. These events develop through mediators secreted by a group of cells called mast cells and basophils, which carry allergen-specific IgE antibodies. These mediators (especially histamine, etc.) Allergy findings of target organs (such as eyes, nose, respiratory tract) occur with the effect of a group of biochemical substances such asWhat are the Allergic Disease Findings?Urticaria - AngioedemaSkin Urticaria: It is itchy bumps of different sizes.It is also called “hives” or “dabaz”.Angioedema: Fluid accumulation in the lower layers of the skin, that is, swelling that occurs with edema. It usually occurs on the face, eyelids, lips and genital area.Eyes and upper respiratory tract; Redness and itching in the eyes,Nasal congestion or runny nose, itchy nose and sneezing.In the lower respiratory tract; Difficulty in breathing, Wheezing (wheezing), Cough.In the cardiovascular system; Palpitation (increased heart rate),low blood pressureIn the gastrointestinal tract, Nausea – vomiting,Abdominal pain or abdominal cramps.In the nervous system; clouding of consciousness,Fainting Anaphylaxis (allergic shock) Although rare, all of these findings belonging to all systems can be seen together and it is called anaphylaxis. It is the most severe form of allergic reaction.
What Are Allergic Diseases?
Although the mechanisms that initiate the allergy are generally the same, clinical findings vary according to the affected organ. Allergic diseases are named according to the findings and the affected tissue and organ system.Common allergic diseases are:allergic rhinitisallergic conjunctivitisAsthma (bronchial asthma)food allergydrug allergybee allergyiAtopic dermatitisUrticaria and angioedemalatex allergy
