Anaphylaxis

Anaphylaxis is a severe and potentially life-threatening allergic reaction. It is characterized by a sudden onset of symptoms, including difficulty breathing, swelling of the lips, tongue, throat, or face, a drop in blood pressure, dizziness, and a fast heart rate. Anaphylaxis can be caused by a variety of triggers, including food, medications, and insect stings. Treatment for anaphylaxis includes the administration of epinephrine, which can reverse the symptoms. In some cases, additional medical care may be necessary. Anaphylaxis occurs when a person’s immune system overreacts to a foreign substance, such as a food, medication, or insect sting. The immune system produces antibodies to fight the allergen, which triggers the release of chemicals, such as histamine, that cause an allergic reaction. The reaction is usually immediate and can be severe. Symptoms of anaphylaxis can range from mild to life-threatening and can include difficulty breathing, swelling of the lips, tongue, throat, or face, a drop in blood pressure, dizziness, a fast heart rate, and hives. If left untreated, anaphylaxis can be fatal. Treatment for anaphylaxis includes the administration of epinephrine, which can reverse the symptoms. In some cases, additional medical care may be necessary. It is important to be aware of the signs and symptoms of anaphylaxis and to seek immediate medical attention if they occur.
