Hives Rash

Hives refers to skin allergic reactions caused by certain allergen substances that might have come in the vicinity of the patient or if the patient had consumed the allergen in his/her food.

Hives rash does not require immediate medical attention unless the hives are persistent and last more than a month. They are crazily itchy and often unsightly.

Symptoms of Hives Rash

Skin hives appear as raised pale or red colored welts on the skin. These hives arrive in clusters and often change shapes and may also relocate frequently.

Often patients find that hives disappear on their own and suddenly there is an onset of hives again. There is associated itching and irritation on the area that has been affected by hives.

They may be located on the arms, trunks, legs, chest etc. Sometimes the face and tongue also might be affected by hives rash. This may cause the face to get swollen abnormally. This special condition of hives rash is also referred to as angioedema.

In cases of angioedema, the condition of the patient may be serious as well as the swelling on the face may constrict the breathing tubes. The patient may find it difficult to swallow in such circumstances. If the condition worsens, there is a requirement of immediate medical help.

What Are The Causes of Hives Rash?

Hives rash can be caused due to anything as it is an allergic reaction on the skin. A person may be allergic to a food substance, any food additive or even an item of furniture.

Hives rash is caused when the mast cells on the skin begin to produce histamines on the skin surface. These mast cells are part of autoimmune system of the body, where the IgE antibodies in the blood stream are triggered as an allergic response to an allergen. Hives rash is the result.

The following allergen substances are found to be commonly responsible for triggering hives rash in the body:

Food substances or food additives, such as eggs, chocolates, shell fish, soy etc and even colors added in the foods may trigger an onset of hives rash. Identifying the causative factor of hives rash is again a big challenge because pinpointing the allergen substance from the variety of foods that a person may have eaten earlier is difficult.

Doctors may ask the patient to undergo a thorough blood and relevant allergy tests to pinpoint the factor that might have triggered the allergic reaction.
