Allergy
An allergy is an immune system response that occurs when the body mistakenly identifies a normally harmless substance as a threat. This substance is called an allergen and can include things like pollen, dust, certain foods, or pet dander. When someone with an allergy comes into contact with an allergen, their immune system reacts by producing a variety of symptoms.
Common symptoms of an allergic reaction can range from mild, such as sneezing or a rash, to severe, such as difficulty breathing or anaphylaxis, which is a life-threatening condition. The severity and type of symptoms can vary widely depending on the individual and the allergen involved.
Allergies are quite common and can affect people of all ages. They can develop at any time in life, even in those who didn’t have allergies as children. Managing allergies typically involves avoiding known allergens and using medications, like antihistamines, to relieve symptoms.
