An allergy is an abnormal immune system reaction to things that are mostly harmless to a person. An allergy happens when the immune system mistakenly believes a substance is harmful to the body and tries to fight it off.
This usually causes reactions such as swelling of the face, vomiting, difficulty in breathing and even fainting. Allergies can be chronic, seasonal or permanent.

Ways of treating allergies
The first thing is to inform everyone close to you about your allergy. This information will help them keep the allergen away from you, whether it’s a certain food or pet animal.
Avoiding environments where the allergen is plenty. This includes avoiding dusty rooms or earth roads if you’re allergic to dust or avoiding damp areas if you’re allergic to mould.
If this does not help, doctors can prescribe medicine to combat the effects of the allergens. Such drugs include antihistamines, eye drops, nasal sprays, allergy shots and even inhalers.
