Allergies

Allergies are exaggerated immune system responses to substances that are normally harmless to most people, known as allergens. When a person with allergies comes into contact with an allergen, such as pollen, dust, certain foods, medications, or animal hair, his or her immune system mistakenly identifies it as a threat and triggers a series of reactions to defend the body. These reactions can range from mild symptoms, such as sneezing, itching, hives and watery eyes, to more severe reactions, such as difficulty breathing, swelling and anaphylaxis, which is a life-threatening medical emergency. Allergies can affect different parts of the body, including the skin, respiratory system, gastrointestinal tract and cardiovascular system. A predisposition to allergies is often hereditary, but can also develop at any stage of life. Treatment of allergies generally involves avoidance of allergens, the use of antihistamines, corticosteroids, decongestants, and in severe cases, administration of adrenaline by auto-injectors in situations of anaphylaxis. In addition, in some cases, immunotherapy therapies can be used to desensitize the immune system to allergens and reduce the severity of allergic reactions over time.
