Description
An exaggerated immune response or reaction to substances that are generally not harmful. Common allergic diseases are:

  • Allergic rhinitis (hay fever)
  • Allergic asthma
  • Allergic conjunctivitis
  • Urticaria
  • Food allergy
  • Latex allergy
  • Insect sting
  • Eczema

Causes
Allergy is caused by an oversensitive immune system, which leads to a misdirected immune response. The immune system normally protects the body against harmful substances, such as bacteria and viruses. In contrast, an allergic reaction is when the immune system reacts to substances (allergens) that are generally harmless and in most people do not cause an immune response.

Allergy is relatively common. Both hereditary and environmental factors have been found to play a role.

  • Runny nose
  • Tearing, burning, or itching eyes
