Psoriasis

Psoriasis is a thickening of the skin with the formation of red patches covered with shiny silvery scales that shed continuously. The lesions – mildly sore and itchy – usually affect the elbows, knees, buttocks, back, and scalp, although the plaques may develop elsewhere (finger and toenails, genitals, anal area, and skinfolds). One to two percent of Americans have some degree of psoriasis, while 10 percent of these have a severe, incapacitating form. About one in twenty have an associated arthritis, commonly of the fingers and toes, but sometimes of the spine.

The fundamental cause of psoriasis is not currently known; however, one in three appears to have some hereditary factor. The essential problem is an overproduction of skin cells. These cells are normally replaced every 28 days. In psoriasis, because of rapid production, replacement occurs in three to four days. The severity of the illness varies widely. An acute attack usually ends spontaneously, but the condition usually recurs. Hot weather, humidity, and sunlight aid, while cold weather hinders, recovery. Emotional stress, an infection such as a sore throat, an injury of the skin, alcohol, and general debility tend to precipitate an attack. In psoriasis the nails characteristically become pitted, contain spots of yellowish discoloration, and toward the tips may separate from their beds.

The best thing you can to treat psoriasis is to keep in good health by adopting a healthful lifestyle. Sunbathing will help to aid recovery, but do not get sunburned. Stay away from things that stress you out. After gently washing the lesions with a mild soap and water, apply an ointment suggested by your physician.
