Ulcer

Ulcer is an open sore in the skin on mucous membrane. A section of the covering membrane, the epithelium , breaks down and dies, leaving a raw area that heals slowly. A wound is not an ulcer.

Ulcers are likely to form on some part of the body which has poor blood circulation. Even a small injury on that part may lead to ulceration. The condition is common on legs with varicose veins. It is important to heal ulcers of the lips or skin, in order to prevent other conditions such as cancer from occurring.

Many persons have peptic ulcers (ulcers in the lining structure) in the stomach. Even more have peptic ulcers in the duodenum, the part of the intestine immediately below the stomach. Some of the causes or conditions that may lead to ulcers include heredity, nervous strain, poor circulation, or bad diet. But too much gastic juice is considered the real cause of stomach ulcers. Excess acid in the stomach keeps the ulcer from healing and help keep it chronic. Ulcers of this kind usually cause pain and distress in the pit of the stomach. They may sometimes bleed, and are most dangerous when they perorate (eat through) the organ. This may lead to peritonitis. Stomach ulcers are treated with alkaline drugs and careful diet. Some ulcers require surgical treatment.<>
Ulcers on the eyeball are dangerous. When a tooth ulcerates, an ulcer may form on the gum when pus has gathered around the root.
