Allergies
An allergy occurs when the body reacts to a substance. This may cause a mild to severe problem. There are different kinds of allergies. The most common allergies are to:
- Things in the air such as pollen, mold, pet dander, or dust.
- Things you touch such as metal, latex, or chemicals.
- Foods you eat or drink such as eggs, peanuts, nuts, milk, soy, wheat, or shellfish.
- Insect stings, such as from yellow jackets, bees, wasps, hornets, or ants.
- Medicines, such as antibiotics.
An allergy cannot be cured, but treatment can help you feel better. The best plan is to avoid the substances that make your symptoms, or signs, worse.
