Urticaria, or hives, are quite common in the general population. Those that come on rapidly and resolve quickly are often due to an underlying allergic cause, and may be brought on by triggers such as foods, environmental allergies, insect stings or medications. Allergists are well-trained to work with patients to diagnose and treat allergic urticaria, as well as educate in avoidance measures to decrease future sympoms.
In addition, long lasting, chronic hives are often not due to an allergic cause, and may be related to other underlying conditions. The management of chronic urticaria is often frustrating for both the patient and the healthcare provider, and may involve trying several different medications. Allergists can help to rule out other underlying conditions causing or contributing to the urticarial outbreaks, and have vast experience in the medical management of hives.
