What is the difference between gastric ulcer and gastric erosion?

Gastric ulcer is usually referred to as gastric ulcer, and there is no difference between the two.

Gastric ulcer is usually a digestive system disease in which the patient has ulcerative lesions in the lining of the stomach or deeper layers. Gastric ulcer may be caused by Helicobacter pylori infection, taking non-steroidal anti-inflammatory drugs, etc. In the case of gastric ulcer, patients may experience stomach pain, loss of appetite, abdominal distension after meals, weight loss, etc. If the patient does not treat the gastric ulcer in time, it will cause the ulcer surface to continue to increase, resulting in complications such as upper gastrointestinal bleeding, pyloric obstruction, gastric perforation, etc.
