Allergies are an overreaction of the immune system to something that is typically harmless. When exposed to an allergen, the body produces antibodies that can cause an array of symptoms ranging from mild to severe. Allergies can affect people of any age and can be a lifelong condition.

Signs and Symptoms

The most common signs and symptoms of allergies include: nasal congestion and sneezing, itchy eyes, runny nose, coughing, hives, and skin rashes. Severe reactions, such as anaphylaxis, can be life-threatening and require immediate medical attention. Anaphylaxis causes swelling of the throat, difficulty breathing, and a drop in blood pressure.

The best way to prevent allergies is to avoid exposure to known allergens. If you are allergic to certain foods, it is important to read labels and avoid foods that contain them. If you are allergic to pet dander, it is best to avoid contact with animals.
