Allergies are hypersensitivity reactions triggered by exposure to certain substances, known as allergens, which can lead to a variety of symptoms that may range from mild annoyances like sneezing and itching to severe, potentially life-threatening conditions such as anaphylaxis. Understanding the types of allergens, recognizing symptoms, and knowing how to manage allergic reactions is crucial for maintaining health and well-being.

Understanding Allergies

Allergies can arise from various sources, including pollen, food, insect stings, pet dander, and medications. The immune system mistakenly identifies these substances as harmful, leading to an exaggerated response. Common symptoms include:

  • Runny or stuffy nose
  • Itchy or watery eyes
  • Skin rashes or hives
  • Digestive issues
  • Shortness of breath or wheezing

Managing Allergies

Effective management of allergies often involves identifying triggers through allergy testing, avoiding known allergens, and utilizing medications such as antihistamines or corticosteroids. In severe cases, an epinephrine auto-injector may be prescribed for emergency situations.

How can I prevent allergic reactions?
