Overview
Allergies are a common condition that occurs when the immune system overreacts to a foreign substance, known as an allergen. Allergens can include pollen, dust mites, animal dander, certain foods, and medications. Symptoms of allergies can vary depending on the type of allergen and can include sneezing, runny nose, itching, hives, and difficulty breathing. Diagnosis is typically made based on medical history, physical examination, and allergy testing. Treatment options for allergies include avoidance of the allergen, medication such as antihistamines or corticosteroids, and immunotherapy. In severe cases, emergency medical treatment may be necessary. Complications can include anaphylaxis, a severe and potentially life-threatening allergic reaction. Management of allergies can greatly improve quality of life and reduce the risk of complications. It is important to consult with a healthcare provider to determine the best course of treatment based on individual symptoms and medical history.
