Peptic ,Duodenac or Esophageal  ulcer
Until the mid-1980s, the conventional wisdom was that ulcers form as a result of stress, a genetic predisposition to excessive stomach acid secretion, and poor lifestyle habits (including overindulging in rich and fatty foods, alcohol, caffeine, and tobacco). Overuse of over-the-counter painkillers (such as aspirin, ibuprofen, and naproxen), heavy alcohol use, psychological stress, and smoking exacerbate and may promote the development of ulcers, especially in someone with H. pylori. Other studies show that stomach ulcers are more likely to develop in older people. The majority of peptic ulcers are caused by a bacterial infection of the stomach called Helicobacter pylori. This infection is often asymptomatic and can be acquired in childhood. The other cause of ulcers is the regular use of aspirin and anti — inflammatory medicines. First off, let's not buy into the myth that ulcers are caused by a bacteria called H. pylori. Just not true. Ulcers are caused by the prior use of a medication that destroyed your mucosal lining, thus leaving your stomach tissue exposed to your own digestive acids, which then eat a hole right through the flesh. Peptic ulcers are holes or breaks in the protective lining of the duodenum (the upper part of the small intestine) or the stomach -- areas that come into contact with stomach acids and enzymes. Duodenal ulcers are more common than stomach ulcers. Comparatively rare are esophageal ulcers, which form in the esophagus -- or swallowing tube -- and are often a result of exposure to medications, like certain antibiotics or anti-inflammatories, or alcohol abuse. Overuse of over-the-counter painkillers (such as aspirin, ibuprofen, and naproxen), heavy alcohol use, psychological stress, and smoking exacerbate and may promote the development of ulcers, especially in someone with H. pylori. Other studies show that stomach ulcers are more likely to develop in older people. Gastric Ulcer. When a peptic ulcer is in your stomach, it is called a gastric ulcer. The symptoms of gastric ulcers are more specific than peptic ulcer symptoms. Duodenal Ulcer. When a peptic ulcer is in your duodenum, it is called a duodenal ulcer. Most people know about two types of ulcers before they get diagnosed with a more specific type of ulcer. Generally, people refer only to stomach ulcers and peptic ulcers. We explain what the difference is between these two, and we also explain more about the lesser known stomach ulcers. Stress ulcer is defined as lesions or erosion on the mucous membrane of the stomach lining which often occurs at the gastric fundus. The erosion can appear superficial and contained in the mucosa which can cause bleeding in the mucosal. The lesion can also penetrate deeper into the submucosa that may cause hemorrhage.  Identification. A peptic ulcer is diagnosed when the lining of the stomach, small intestine or esophagus develops sores, states the Mayo Clinic. Peptic ulcers are caused by the bacteria Helicobacter pylori or H. pylori. For reasons not well understood, this bacteria, which normally exists in the lining of the stomach, can sometimes cause an inflammation of the stomach or intestines. While stress alone does not cause peptic ulcers, learning to manage stress can help to control symptoms and reduce the risk of complications. The first step is to understand what a stomach ulcer is and the role stress plays in this condition. Ordinary peptic ulcers are found commonly in the gastric antrum and the duodenum whereas stress ulcers are found commonly in fundic mucosa and can be located anywhere within the stomach and proximal duodenum. Stress ulcers, as defined by overt bleeding and hemodynamic instability, decreased hemoglobin, and/or need for transfusion, was seen in 1.5% of patients in the 2252 patients in the Canadian Critical Care Trials group study. Causes of stomach ulcers. Stomach ulcers are usually caused by Helicobacter pylori (H. pylori) bacteria or non-steroidal anti-inflammatory drugs (NSAIDs). These can break down the stomach's defence against the acid it produces to digest food, allowing the stomach lining to become damaged and an ulcer to form.  This includes stomach, or peptic, ulcers. While stress alone does not cause peptic ulcers, learning to manage stress can help to control symptoms and reduce the risk of complications. The first step is to understand what a stomach ulcer is and the role stress plays in this condition. Stomach and duodenal ulcers are usually due to one of two causes: the bacterium Helicobacter pylori or nonsteroidal anti — inflammatory drugs (NSAIDs) like aspirin, ibuprofen, and naproxen. An ulcer, regardless of the cause, can cause abdominal pain, bleeding, or even cause a hole (perforation). An ulcer is maintained by an acid environment in the stomach and pepsin, which is produced in the stomach. Chronic infection with H. pylori causes an increase in acid.

Ulcers are caused by the prior use of a medication that destroyed your mucosal lining, thus leaving your stomach tissue exposed to your own digestive acids, which then eat a hole right through the flesh.
