Allergy Disease: Allergy Symptoms, Causes, Types and Treatment Tips

Allergy disease is caused due to allergen, a non-symbiotic antigen that stimulates hypersensitivity reaction. Every human has immune system to protect the skin and body from such antigens. But some people have the higher level of sensitivity. After entering in the system of such extra sensitive people, the antigen substance causes allergy symptoms. The antigen enters in the human body through food, breath, injection, or may be through skincontact.The allergy disease can be triggered through dust, certain drugs, chemicals, animal hair, fur, pollen grains and many foodstuffs. The allergies can be classified in two categories: 

Seasonal Allergies

Recurring Allergies

The seasonal allergy symptoms are expected to be during some particular seasons in a year. They are mostly triggered by the ingesting, inhaling or injecting certain substances such as pollen grains, weed or grasses and may lead to a continuous allergic response. The recurring allergies can arise at any point of time throughout the whole year. Mostly such allergies are caused by the fur and hairs of pet animals or indoor/outdoor dust.

Another type of allergy disease is known as food allergy. This is caused due to consuming certain eatables such as peanuts, corn, meat, eggs, milk, chocolates, etc.
