What are the symptoms of gastrointestinal bleeding

Gastrointestinal bleeding is also known as gastrointestinal bleeding. The digestive tract is divided into the upper and lower digestive tracts. Upper gastrointestinal bleeding can be manifested as hematemesis, that is, blood vomited from the mouth through the stomach and esophagus; upper gastrointestinal bleeding can also be manifested as black stool, that is, tarry black stool. Lower gastrointestinal bleeding normally does not show hematemesis, but can be manifested as jam red stool. If the bleeding site is lower than the sigmoid colon or rectum, it may show blood on the surface of the stool. No matter which of the above symptoms, it is necessary to see a hospital promptly to determine the cause of gastrointestinal bleeding and timely treatment.
