Histamine Response

Histamine response refers to the body's reaction to allergens or irritants, involving a chemical called histamine. When exposed to something harmful, the immune system releases histamine to help defend against it. This can lead to symptoms like itching, swelling, and sneezing as blood vessels expand and inflammation occurs. While this response is part of normal immunity, in some people it can become excessive, causing allergic reactions. Antihistamines are medications that block histamine's effects, helping to relieve symptoms. Understanding this response can help us manage allergies and related health issues effectively.
