Causes of allergic diseases

Allergic diseases have many different triggers, including pollens, fungi, mites, animal epithelia, drugs, food, insect bites, perfumes and powders. People at risk should be aware of any signs to avoid getting sick or aggravating themselves. Vaccines against allergic diseases, known as hyposensitizing vaccines or allergy immunotherapy, are the treatment that can change the natural course of these diseases by affecting the mechanism that triggers or aggravates them. People suffering from allergic diseases are usually sensitive to more than one allergen present in the constituents of the environment. Allergy immunotherapy consists of applying increasing doses of the responsible allergen to achieve tolerance; therefore, it can potentially be applied regardless of the allergen causing the disease.
