Allergies are a common condition in which the immune system overreacts to a substance, causing symptoms such as sneezing, itching, and congestion. Allergies can be caused by a variety of triggers, including pollen, dust mites, animal dander, and certain foods.
Symptoms of allergies can vary in severity, but may include runny nose, sneezing, itchy or watery eyes, and hives. In severe cases, allergies can cause anaphylaxis, a life-threatening reaction that requires immediate medical attention.
Treatment for allergies typically involves avoiding triggers whenever possible and using medications to manage symptoms. Medications may include antihistamines, decongestants, and nasal corticosteroids. In addition to medication, some individuals with allergies may benefit from immunotherapy, a treatment in which the immune system is exposed to gradually increasing doses of the allergen over time to build tolerance.
It's important for individuals with allergies to work with their healthcare providers to identify their triggers and develop a treatment plan. Allergy testing may be necessary to identify specific triggers and inform treatment.
