How does allergy happen?

An allergy happens when the body recognizes a harmless component as a danger. The immune system quickly responds and causes not many symptoms of allergy. It is an unseemly harmful reaction that happens unnaturally.

Any sensitivity has five phases for development:

Stage 1:

The allergen contacts the organic cells through air, contact, or food.

Stage 2:

The strong system gets down on plasma cells and makes antibodies called immunoglobulin E as a response to an allergen.

Stage 3:

The IgE comes inside the skin, respiratory parcel, or gastrointestinal strategy and sits idle.

Stage 4:

When the body gets presented to the allergen once more, the IgE gets bound to the allergen and responds, believing the allergen to be a trespasser.

Stage 5: 

This stage happens following 24 hours of the past stage. The cells of the immune system draw nearer to the influenced territory and delivery the synthetics.
