What Is Allergy And Its Symptoms

What Is Allergy

An allergy includes itchy eyes, runny nose, or rashes on the skin, which may worsen the sense of sight, smell, touch, and tastes. All of these occur because of the overreacting immune system of the body.

The number of these Allergies is increasing by 5 per cent each year and from that half of the children. This mostly occurs in the UK.

Causes of an Allergy

Because of the substances in the environment allergic reactions have occurred which is known as allergens. Allergens hold protein, which is included in the food whatever we eat.

Allergens have commonly occurred into the following,

  • Pollen of grasses and trees, dust particles in house, pets like dogs, cats, moulds, bees and insects, chemicals, medicines, eggs and milk.
  • Allergens less commonly occurred in the fruit, latex and nuts.
  • Non-protein allergens contained in drugs like penicillin. For the response of an allergy they have to bind with protein.
  • The immune system of the person affected byby allergens produces the antibody of the particular type because these blood cells release chemicals and cause allergic reaction’s symptoms.

After causing the allergic reaction

Antibodies are useful for protecting the body from parasites, infections and viruses. But the allergic people’s immune system wrongly identifies the type of allergens and makes antibodies against the allergy.
