What is the pathophysiology of gastritis?
Pathogenesis. The continuous mucosal injury due to long-standing H. pylori infection, leads to atrophy of stomach. This continuous pathological process results in erosion or ulceration of the mucosa leading to the destruction of the glandular layer and followed by fibrous replacement.
How is a bleeding ulcer treated?
Ulcers are treated with acid-blocking drugs called proton pump inhibitors (PPIs) or H2 blockers. They can be taken orally, but if you have a bleeding ulcer, they can also be taken intravenously. Cameron ulcers are usually treated with PPIs, but sometimes surgery is needed to repair the hiatal hernia.

What is the difference between a gastric and peptic ulcer?
A peptic ulcer is a sore on the lining of your stomach or the first part of your small intestine (duodenum). If the ulcer is in your stomach, it is called a gastric ulcer.
How do you stop a bleeding ulcer?
Air is used to expand the digestive tract. Once the ulcer is located, tools are passed through the scope to stop any bleeding. These may include clips or devices that use heat or electricity. In some cases, alcohol or adrenaline (epinephrine) is injected directly into the ulcer to help reduce bleeding.

The use of NSAIDs increases the frequency of ulcer bleeding about four- to sixfold on average. Additional factors such as advanced age, concomitant use of corticosteroids or anticoagulants, prior ulcer complications and co-morbid diseases may further increase the risk of bleeding.
What is the best treatment for bleeding ulcers?
Surgery is the best option available for treating bleeding ulcers. For severe cases of bleeding, endoscopic surgery is done to arrest massive bleeding. The surgeon would seal the blood vessel opening that bleeds by the technique of cauterization. He may also push strong solutions that stop bleeding in the blood vessel.
