What are the common diseases in gastroenterology?

Common gastrointestinal diseases mainly include gastritis, gastric ulcer, duodenal ulcer, acute and chronic enteritis. Among these, gastritis may be triggered by factors such as Helicobacter pylori infection and irregular eating habits, while gastric ulcers may be associated with Helicobacter pylori infection or consumption of spicy foods. These conditions commonly cause symptoms such as abdominal pain, bloating, nausea, vomiting, and acid reflux. Additionally, functional gastrointestinal disorders such as functional dyspepsia and irritable bowel syndrome, as well as organic gastrointestinal diseases such as gastric tumors, stomach cancer, and colorectal cancer also fall within the scope of gastroenterology. Patients should seek timely medical attention when experiencing related symptoms for accurate diagnosis and effective treatment.
