There are several different types of hives. some hives may appear as lumps or bumps without any reason. some may find these lumps or bumps emerge after they have eaten or drank something their body does not accept. Hives may appear quickly or in some cases may be due to an underlying cause or may be hereditary. In the majority of the outbreak of hives, the exact cause of hives is not known.
Urticaria is a medical name for skin that has been the appearance of pale red bumps, swollen patches or welts that suddenly appear. This can be due to allergies or due to other causes. The body may encounter a substance causing an allergic or sensitive reaction. When this happens the body releases histamines and other chemicals into the bloodstream. This process causes tiny veins to begin to leak fluid which becomes trapped in the skin and membrane lining. as the leakage continues, swelling of the skin will rise as hives. Hives will not disappear until the body is able to reabsorb the liquid.
This type of hive may attack at any age, but mostly is seen in adolescents. It appears as a rash and may be red and very itchy with a white raised circle. If the rash begins to swell, spreading can happen causing each welt to join together. If they swell deep into the body tissue they are known as giant hives or Angioedema.
This form of hives is considered rare. It is caused by exposure to the sun to areas of the body which is usually covered. Such areas include the belly or the back. This type of hive will develop quickly, but will disappear within an hour after exposure. A physician can perform a test and determine what type of treatment should be administered.
Angioedema is painful and unpleasant in appearance. with this swelling it does not become itchy, but may appear around the lips and eyelids. This type of hive may also be located on the hands, feet, throat and sometimes the genitals. This type of hive may last longer than regular hives, but generally goes away in less than 24 hours. A severe case may consist of difficulty in breathing, difficulty in swallowing, digestive upsets and fever. Hives can also produce swelling in the internal organs.Acute Hives
Acute hives are those lasting more than six weeks and may either be Urticaria or Angioedema. It may be difficult to identify which hive a patient is experiencing.
Exercising may form very small hives due to the temperature of the body rising. This type of stress causes a warming of the body. The hives may last half an hour.
Our body may react to hives in different ways. Hives may appear due to stress, food, exercise, insect bites or bee stings. If any reaction appears that may seem life threatening, it is important to call for assistance immediately. Emergency treatment may be required.
