Allergies are when the body’s immune system reacts to a harmless substance such as pollen, dust, dander, foods and insects. The symptoms can range from mild to life threatening depending on the individual. An allergic reaction occurs when your body has a reaction to an allergen and releases histamine. Most allergies are easily treated.
More than 50 million people suffer from allergies in the United States. Allergy testing is available through blood and skin tests and can be treated with antihistamines and decongestants. Some common allergy symptoms are:
- Rash or hives
- Shortness of breath
