Urticaria
Urticaria Causes
Urticaria is most commonly the body's reaction after it makes contact with allergens. In the case of food allergies, the disease is caused by consumption of dye, nuts, eggs, fish, nuts and acid derivatives. It could also be a result of intake of drugs such as sulphonylurea glimepiride, penicillin, aspirin, sulfonamides, clotrimazole, among others. Scratching one's skin, vibration, cold, heat, and emotional stress may also lead to the disease.
Urticaria Definition
The skin disorder physical urticaria (or urticaria) usually results from allergic reactions to certain substances. It is characterized by the swelling of the skin, called welts or uredo, on different parts of the body, such as the face, throat, ears, lips, and tongue. The welts, whose sizes may grow up to that of one dinner plate, commonly itch severely, burn or sting.
Urticaria Diagnosis
The skin swelling are unmistakable signs of the disease, however, blood and skin tests are needed to prove if this is an allergy and to trace the cause of the allergic reaction.
Urticaria Symptoms and Signs
Welts, which are red-colored and have defined edges, appear on the skin's surface. It is possible for these swelling skin to spread, enlarge, and join together and form bigger uredos. These may also alter their shapes or disappear and appear again after a few minutes or even hours. Pressing the center of welt changes its color to white.
Urticaria Treatment
Treatment of the disease poses a challenge for medical doctors as no single medication has been proven to control or cure it. Some types of the disorder are resistant to treatment, while in long-term cases, drugs could lose their effectiveness. The welts could also disappear without treatments. It is therefore particularly useful to identify to triggers, and avoid exposure to these substances.
