A peanut allergy occurs when the body responds abnormally to peanuts. The reaction may range from mild to life-threatening. Even a very small amount of peanuts can lead to a serious reaction.
This condition may be serious. It requires care from a doctor.
The allergy occurs when your body is exposed to peanut proteins. The body mistakes the proteins as harmful substances, and the immune system releases chemicals into the bloodstream, which causes symptoms.
Coming in contact with peanuts can occur by:
- Eating peanuts, foods containing them, or foods that came in contact with them
- Touching peanuts
- Inhaling particles containing peanuts, such as peanut flour
