Hives or urticaria is a common skin condition seen in both adults and children that can occur as a single episode (acute urticaria), or less commonly, it may recur multiple times for longer than 6 weeks (chronic urticaria). Hives is caused due to the immune system releasing histamine into the skin. This substance causes the redness, swelling and itching. The rash can last from minutes to hours but often disappears without a trace within 24 hours.
Alternative names: Urticaria, welts, wheals, nettle rash.

WHAT CAUSES HIVES?
Hives are usually caused by an allergic reaction. Triggers can be identified which often include allergies, environmental temperature changes, pollen, insect bites, animal fur, emotional stress and food. Even though the rash of urticaria is identical in appearance to that caused by an allergic reaction, in most cases no obvious cause can be found. This is classed as ‘idiopathic urticaria’. Hives can also be experienced as a result of stress, tight clothes, exercise, illness or infections.
People who have allergies are more likely to have hives and other health conditions may make you more vulnerable to developing hives.
WHAT ARE THE SYMPTOMS/TYPE OF HIVES?
Hives usually appears as a series of raised, red bumps that come up within minutes and can resemble mosquito bites or nettle rash. It can be limited to a small area or span large expanses of the body. Sometimes there is swelling of the face and eyes (angio-oedema). The rash often resolves over a period of an hour or two, but might last as long as 24 to 36 hours.
There are a number of different types of Hives:
Hives can be caused by an allergic reaction to a common irritant you may be sensitive to such as foods, animal fur, medications, pollen, insect bites.
Chronic Idiopathic urticaria
If the source of hives can’t be identified and the hives are seen for long periods of time, they are known as chronic and idiopathic. About 75% if hives cases are idiopathic which can make them harder to treat and symptoms are experienced for longer.
Temperature induced hives
Changes in temperature caused by cold or hot weather, water, sunlight and exercise can cause hives in some people.
HOW CAN HIVES BE TREATED?
Most cases of acute urticaria get better without treatment and the symptoms can be effectively treated with antihistamines. For long-term urticaria the treatments aim to relieve symptoms rather than act as a cure. Identifying potential triggers is an important first step though usually a specific offender cannot be found.
Available treatments include antihistamines, short courses of steroid tablets and in very severe, chronic cases medications to dampen the body’s immune system (such as ciclosporin) can be beneficial. Our specialist dermatologists can offer effective treatment to patients to help control your symptoms.
