What are the causes of bloating and blood in stool? Feeling bloated and having blood in stool at the same time indicates that there is bleeding in the digestive tract. If the bloating is accompanied by tar-like black stools, it indicates a problem in the upper gastrointestinal tract, which is usually seen in acute gastritis, peptic ulcer with bleeding, gastric cancer with bleeding or esophagogastric fundic varices with a small amount of bleeding. If the bleeding is relatively large, it may be bright red blood stools with even vomiting of blood, such as cardia tears. Some of the above-mentioned etiologies present with a large amount of bleeding in a short period of time and can also present with a patient with significant upper abdominal distention and gastric distention accompanied by bleeding. Of course, if the patient considers bleeding from the lower gastrointestinal tract, such as some polyps, tumors, or inflammation of the colon with bleeding, it can also be accompanied by upper abdominal distention and indigestion. In any case, the presence of gastric distension and blood in the stool is somewhat serious and should be seen immediately.
