Ulcers

Ulcers on the skin are caused by an infection with certain kinds of bacteria called the Enterocci and the Streptococci. These bacteria invade the skin tissues and multiply, causing the ulcer, or sore, to erupt on the skin surface. Experts believe that many people with bacteria-related ulcers acquired these infections during a stay in a hospital. When bacteria are transmitted within hospital settings, the infection is described as nosocomial. Skin ulcers caused by bacteria are treated with antibiotics.

Others skin ulcers are caused by constant pressure against the skin that does not allow air circulation. For instance, people who are bedridden for long periods of time frequently develop ulcers on the back, buttocks, and backs of the legs. If these ulcers are not treated promptly, they can quickly become infected with bacteria, and deep wounds can result. Pressure ulcers can be avoided in the bedridden if patients are turned periodically throughout the day so that all the surfaces of the body are exposed to air.

Still another type of skin ulcer primarily affects people with diabetes. One of the complications of diabetes is neuropathy, a condition in which nerve endings become irritated. The nerves may eventually die and the area in which the nerves are located becomes anesthetized. Diabetic patients typically experience neuropathy in the feet. If they injure their feet, the neuropathy may prevent them from feeling any pain from the injury. The injury worsens until a full-blown ulcer develops. People with diabetes are encouraged to examine their feet daily for signs of injury and to seek prompt care for any foot injury, even minor injuries.
