What are the most common causes of hive rash?

The hive rash, also known as urticaria, is most often associated with an allergic reaction and in many chronic cases allergies are responsible. There are other possible causes and short -term hive attacks are often caused by a viral or bacterial infection. Heat, cold or narrowing from tight clothing or jewelry could irritate the skin and cause to form a rash. The hives may also be a symptom of health, such as thyroid, kidney or liver dysfunction, and chronic cases should obtain medical attention to determine the cause.

The hives are raised, itchy, red welds on the skin. These welds often appear in clusters, and although they may occur anywhere on the body, they are often observed on the face and limbs. The hives appear quickly and the individual welds can be cleaned quickly while new ones are formed, which seems to change shape and location. The welds occur when the capillaries just below the skin seep liquid, causing the area of ​​inflatingswelling.

allergic reactions usually cause a hive rash. When an allergen is introduced by suffering allergy, the body reacts by the production of histamines. These histamines trigger a capillary escape that causes the welds to form.

Allergies are exposed to allergens by ingestion, inhalation or skin contact. Medicines such as antibiotics, painkillers and anticonvulsants are potential allergens. Foods such as nuts and molluscs are closely associated with allergies, but almost any food can potentially cause allergic reactions, including a rash. Pollen, mold and pet can cause similar results when inhaled. Examples of exposure through contact with the skin include bite of animals and scratches or handling plants.

Another probable cause of hives is infection. Viral, bacterial and fungal infections may be responsible for the production of Rash. Parasites aso are pinworms and giardia, they can also cause hives.

Heat and sweat and sweat can cause skin irritation, resulting in hives. Tight clothing and jewelry can reduce sweat and sweat traps, with similar results. Low temperatures can also irritate the skin and the cold is as likely as the heat for the production of hives.

Many sources of hives cause irritation directly exposed skin. The hives may occur anywhere on the body, but rashes are particularly likely on exposed skin of the face and limbs. The hive rash can offer a source guide.

Often there is no definitive cause of the rash. Experts agree that viral infection is usually the most likely cause for these cases, especially when the rash spreads to other patients in a short time. Other common causes, such as allergens, mold and heat, although less likely, should not be excluded when trying to identify the source of hive rash.
