Hives (or Medically Urticaria) is an allergic condition of the skin that may last for a few days or can take few weeks to fade. Hives appear as the raised pink, itchy bumps or welts of variable sizes and shapes on the arms, leg or back. Hives generally occurs as a cluster on the skin and the skin appears totally reddish. mostly women are more prone to the problem of hives than men. a normal case of hives usually disappears within 24 hours whereas a chronic Urticaria can persist more than six to seven weeks. a chronic hives patient tends to get hives repeatedly. Also extensive itching, irritation disturbs him a lot.
Some of the symptoms regarding chronic hives can be swelling on the face primarily near the mouth and eyes. Hives very rarely goes up to life threatening but in those cases a patient suffer from anaphylactic shock and he finds it very difficult to breathe. Actually in those cases the food pipe of the patient narrows down due to swelling of the throat and glands that can sometime led to the unconsciousness situation. Also, the blood pressure of the patient also falls down.
Hives are caused by the allergic reaction takes place in the body due to intake of certain food substances, medicines, infection or some other factors. Because of this allergic reaction the immune system of body tends to produce IgE antibodies and these antibodies bind the mast cells which in turn promotes the growth of histamine inside the body. in most of the cases the actual factors causing hives remains unidentified. however there are some of the factors which invariably trigger the allergic reactions in the body which include nuts, chocolates, pollen grains, cats’ dander, some antibiotics like penicillin, aspirin, etc.
If you are suffering from chronic hives then in that case it is good to consult your doctor. As we know almost 90 percent of hives causes remain unidentified but if a doctor somehow know the correct cause then it will be a lot easier to completely remove the problem. most of the dermatologists try to find the factor responsible of the allergic reaction by analyzing the patient’s history with dietary habits, general habits, etc.
Most of the doctors give the patients antihistamine like Benadryl but in some cases a doctor may start with low sedating antihistamine like Cetirizine or Allegra. If these drugs are found less effective then doctor will prescribe you some other medications like oral corticosteroids and epinephrine, etc.
