| Hives The eruption of red marks on the skin that are usually accompanied by itching. This condition can be caused by an allergy (e.g. to food or drugs), stress, infection or physical agents (e.g. heat or cold). Also known as hives. Hives are raised, itchy welts on the surface of the skin caused by hypersensitivity to a substance. When the body encounters a substance that it is allergic or sensitive to, it releases histamines and other chemicals into the bloodstream. As a result, the capillaries and tiny veins leak. The leaking fluid gets trapped in the skin and lining membranes, which causes the localized swelling seen with hives. The welts, which are also called wheals, may remain small, or may spread large enough to join together. With hives, the center of the welt blanches, or turns white, when pressed.
