Allergies and the immune system response.

Akaram Kamran

Allergies occur when a person's immune system reacts abnormally to normally harmless chemicals. It can also happen when a person's immune system is triggered by foreign substances like pollen, bee venom, pet dander, or even particular foods. Antibodies are chemicals produced by a person's immune system. When you have allergies, your immune system produces antibodies that label a particular allergen as harmful, even if it isn't. When you come into touch with these allergens, your immune system may react by inflaming your skin, sinuses, airways, or digestive system. Each patient's level of allergy severity varies. It might be anything from a minor annoyance to a life-threatening allergic reaction. Although most allergies are incurable, there are a variety of therapies that can help alleviate the symptoms.
