Allergic reactions

Allergic reactions occur when the immune system overreacts to a harmless substance, called an allergen, and produces a response that can cause a variety of symptoms. These symptoms can range from mild, such as itching and hives, to severe, such as anaphylaxis, which is a life-threatening emergency. In this article, we will discuss the causes of allergic reactions, symptoms of allergic reactions, and strategies for managing and preventing allergic reactions.

• Carrying medication: If you have a known allergy, it is important to carry medication such as an epinephrine auto-injector (EpiPen) with you at all times in case of an emergency.
• Seeking medical attention: If you experience symptoms of an allergic reaction, seek medical attention immediately, especially if you experience difficulty breathing or signs of anaphylaxis.
• Allergy testing: Allergy testing can help identify the specific allergens that trigger your symptoms, which can help you avoid exposure and manage your symptoms more effectively.
