Everything You Need to Know About Allergies

Introduction
Allergies are a common immune system response to a foreign substance that is not typically harmful to your body. The immune system perceives the substance, called an allergen, as an outside invader and attacks it, which can lead to various symptoms. In this article, we will explore everything you need to know about allergies, including their causes, symptoms, and treatments.

Causes of Allergies
Allergies can be caused by a variety of allergens, including pollen, dust mites, animal dander, foods, medications, and insect stings. The reason why some people develop allergies while others do not is still not fully understood. However, several factors can increase your risk of developing allergies, such as genetics, environmental factors, and a weakened immune system.
