What is Hives?
Hives (urticaria) is an itchy rash caused by a small amount of fluid leaking from blood vessels just below the skin surface. This skin reaction may vary from person to person in color and size. Conditions that usually trigger hives can be; infections, allergies, certain foods, medications or additives, excessive heat or exercise.
Most of the time, hives are harmless and go away within 1-2 weeks without leaving permanent scars. Sometimes it may repeat or take longer than six weeks. It is called chronic hives if it stays for more than six weeks. If chronic hives develop, hives repeat or serious hives develop, they should be examined in detail.
What are the Causes of Hives?

Allergy doctors are making investigations based on information obtained from history to determine the cause of the hives.
If medicines are suspected as the cause of hives, special tests are made from the blood, and if necessary, drug allergy tests and drug provocations to diagnose.
Sometimes hives can be caused by thyroid gland, liver diseases, rheumatic diseases and autoimmune diseases. Therefore, examinations are made for these diseases when necessary. Urticaria can develop in one or three of the patients with physical or non-physical stimuli. Approximately one-third of children and adults with hives may develop hives due to stimulations. In order to investigate these reasons, hives stimulation tests are performed in our center. Hives stimulation tests are time-consuming and detailed tests and can be performed at our center.
