I know that there are 4 and that the bacteria casuing them is helicobacter pylori An ulcer is an open sore, or lesion, usually found on the skin or mucous membrane areas of the body.
An ulcer in the lining of the stomach or duodenum, where hydrochloric acid and pepsin are present, is referred to as a peptic ulcer.
When the ulcer is in the stomach, it is called a gastric ulcer.
When the ulcer is in the duodenum, it is called a duodenal ulcer.
Astomach ulcer (also called a peptic ulcer) is a small erosion (hole) in the gastrointestinal tract. The most common type, duodenal, occurs in the first 12 inches of small intestine beyond the stomach. Ulcers that form in the stomach are called gastric ulcers. An ulcer is not contagious or cancerous. Duodenal ulcers are almost always benign, while stomach ulcers may become malignant.
Stomach ulcer disease is common, affecting millions of Americans yearly. The size of a stomach ulcer can range between 1/8 of an inch to 3/4 of an inch.
The direct cause of peptic ulcers is the destruction of the gastric or intestinal mucosal lining of the stomach by hydrochloric acid, an acid normally present in the digestive juices of the stomach. Infection with the bacterium Helicobacter pylori is thought to play an important role in causing both gastric and duodenal ulcers. Helicobacter pylori may be transmitted from person to person through contaminated food and water. Antibiotics are the most effective treatment for Helicobacter pylori peptic ulcers.
Injury of the gastric mucosal lining, and weakening of the mucous defenses are also responsible for gastric ulcers. Excess secretion of hydrochloric acid, genetic predisposition, and psychological stress are important contributing factors in the formation and worsening of duodenal ulcers.
Another major cause of ulcers is the chronic use of anti-inflammatory medications, such as aspirin. Cigarette smoking is also an important cause of ulcer formation and ulcer treatment failure.
An esophageal ulcer is a hole in the lining of the esophagus corroded by the acidic digestive juices secreted by the stomach cells.
An esophageal ulcer is usually located in the lower section of your esophagus. It is often associated with chronic gastroesophageal reflux disease (GERD).
Esophageal ulcers are not contagious. You cannot catch them from someone else.
*** Esophageal ulcers may be a symptom of another disease or condition. Esophageal ulcers are often common in GERD. Bleeding from esophageal ulcers may cause iron deficiency anemia.
The direct cause of esophageal ulcers is the destruction of the lining of the esophagus H. pyloridus bacteria. H. pyloridus bacteria is usually found in the stomach.
Other common causes of esophageal ulcers are:
Chronic use of anti-inflammatory medications
Smoking cigarettes
Chewing tobacco
GERD
Bulimia
Ok for I found peptic, stomache, duodental & Gastric... though tecniccally its only two kind, but four names... does that help? I'm not sure of the 4 known ulcers but there's petic, gastric and dudenol can't spell that. H Pylori bacteria isn't responsible for all ulcers. I have stomach ulcer and the test for H Pylori came back negative. go here take a look
