​​​​​​​​​​Overview of allergy and immunology

Baylor Scott & White Health has allergy and immunology specialists (often called allergists) on the medical staff who can help identify your allergy triggers and manage your symptoms.

Allergies are problems of the immune system. An allergen is anything that causes the body's immune system to release histamine, one of the chemicals that cause allergy symptoms.​

Most allergic reactions happen when the immune system reacts to a false alarm. Normally, the body defends itself against harmful things, such as viruses or bacteria. But the defenses also attack mild things, so allergy symptoms can be caused by dust, mold, pollen and other environmental triggers at various times of the year (often called seasonal allergies), depending on your sensitivities.
