Hives

Hives

Hives is a skin disease. It refers to a condition when red welts appear on the surface of the skin. These welts are often itchy and can be raised such that they will appear like bumps. Hives is also known as Urticaria in medical circles. Though Hives can be caused by non allergic causes, more often than not the causes of hives are allergic in nature. Indeed, hives that last for a short duration of time, usually less than five or so weeks is caused by allergic reactions and is simply referred to as acute hives or acute urticaria. On the contrary, chronic hives or chrionic urticaria usually lasts a longer period usually more than six weeks and are less likely to have been caused by allergic reactions.

 

Some of the causes of urticaria  that are rarely experienced are pressure, induced friction, extreme temperature changes, sunlight and sometimes even exercise. Indeed, most cases of chronic urticaria have unknown causes. We refer to them as idiopathic causes, with most of the patients being autoimmune. When the chronic form of hive is as a result of viral infection, then we refer to it as viral exanthema.

Hives is often classified depending on its magnitude and cause. Apart from the acute and chronic hive, we have the drug induced type of hives, physical hives, hives caused by pressure or delayed pressure, cholinergic or stress induced hives, exercise induced hives or anaphylaxis and vibratory angioderma among many others. The drug induced type of hive is caused by allergic reactions from consuming drugs such as penicillin, anti-convulsants, aspirin, sulfonamides and suphonylurea among other anti diabetic medicines. Physican hives is caused by aggressive stroking of the skin, more commonly in medical terms as Dermotograhism. Luckily, the welts that appear on the skin due to physical abrasion usually disappear within one hour or so, even as quick as thirty minutes.

 

 

Causes of Hives

  • The body usually reacts to allergies by production of chemical substances called histamine which are released into the bloodstream. The resultant itching of the skin followed by swelling is the major cause of hives.  When the swelling is concentrated around the lips, eyes or the face then it is called angioderma.
  • Certain medications are also known to cause hives. So many anti-diabetic medicines have been documented to produce these ill side effects on patients. A common victim is the sulphonyurea glimepiride that trades ass the Amaryl. Other common drugs are the dextroamphetamine, ibuprofen, aspirin, clotrimazole, sulfonamides, penicillin and the anticonvulsants.
  • Certain foods are also a common cause of allergies leading to development of hives. Nuts and shellfish are specifically notorious for adult allergies. In children, peanuts, wheat, soy and even eggs can cause hives. A patient usually has only one food that can cause him or her allergies. Exposure to certain types of bacteria such as the Helocobacter pylori or the streptococcus is also a possible cause.
  • Common physical allergens that cause hives include contact with animal dander, especially for dogs and cats.

 

Other causes of hives are;

 

  • Reaction to water. This is aquagenic cause and is exceedingly rare.
  • Reaction to body heat like a hot shower or after an intense exercise. This I referred to as a cholinergic cause.
  • Chronic cold hives is caused by reaction to very cold substances, water or the weather. This kind of hives is much worse when the temperature change is sudden from normal to very cold
  • As aforementioned, reaction to very aggressive skin scratching can also result to swelling and formation of the red welts that is called welts. This is a dermatograhic cause of hives.

 

 

Symptoms of Hives

The symptoms of hive usually manifest themselves on the skin as follows

 

  • Appearance of raised areas on the skin that are surrounded by a red base to form bumps on the skin. These areas are called wheals.
  • Skin bumps that are pale red
  • Itching.
  • When the wheals get bigger and larger, they by join to form an even larger flat raised section of the skin.
  • Hive can show an unpredictable behavior. They may get bigger, change shape, spread, disappear and sometimes reappear within hours and sometimes within minutes. A true hive come and goes. When the wheal is pressed, it can change its color from red to white a process that is called blanching.
  • Sometimes the fluid leakage happens from within much deeper blood vessel. This type of condition is referred to as angioderma. When individual hives are painful and ofen last for more than a day and they leave ugly bruises as they heal then the patient has a serious condition and we refer to this as urticarial vasculitis.
  • Swelling of the throat. This can lead to blockade of the air passage hence chocking the patient
  • An extreme manifestation of hives is when the whole body becomes allergic causing a life threatening difficulty in breathing. This is an extreme case of anaphylaxis.
