Who proved that peptic ulcers does not occur because of lifestyle reason but it is caused by a bacteriam?
Answers
Peptic ulcers occur in the stomach (gastric ulcers) and the first part of the small intestine (duodenal ulcers). They result from an imbalance between factors that help maintain the protective lining of the stomach and duodenum and factors that can lead to damage and erosion of this mucosal lining.
Most peptic ulcers are caused by either infection with Helicobacter pylori or regular use of medicines called non-steroidal anti-inflammatory drugs (NSAIDS), including aspirin. Almost all duodenal ulcers are associated with H. pylori infection, while stomach ulcers are commonly caused by NSAID use.
In the past it was believed that peptic ulcers were caused by stress, poor dietary habits (including eating too much rich, fatty or spicy foods), alcohol and caffeine. It’s now known that these things don’t cause peptic ulcers, but they may increase the amount of acid made in your stomach and make your symptoms worse if you do have an ulcer
