Gastrointestinal bleeding can be determined by the patient’s past medical history such as peptic ulcer, symptoms such as blood in stool, vomiting blood, and clinical examination.
1. Past medical history: If the patient has a history of other gastrointestinal diseases, it may lead to the occurrence of gastrointestinal bleeding. For example, anal fissure, ulcerative proctitis, ulcerative colitis, colorectal tumors, etc. can lead to lower gastrointestinal bleeding, peptic ulcer, ruptured varices at the base of the stomach and bleeding, acute erosive hemorrhagic gastritis, etc. can lead to upper gastrointestinal bleeding.
2. Symptoms: patients with gastrointestinal bleeding may have special symptoms, such as black stool, bloody stool, vomiting blood, dizziness, panic, dry mouth and fatigue, and so on, which can be used to determine whether there is gastrointestinal bleeding.
3. Clinical examination: patients can be examined through blood and stool routine, fecal occult blood, endoscopy, angiography, CT scan and other ways to determine whether there is bleeding.
Patients with suspected gastrointestinal bleeding should go to the hospital for examination in a timely manner to clarify their condition and then seek medical attention.
