Reasons for Black and Loose Stool:
1. Dietary Factors: Consuming too much greasy and high-protein food can slow down bowel emptying, resulting in black stool that often smells unpleasant.
2. Consumption of Certain Medications or Foods: Stool discoloration may occur after stool staining, such as taking traditional Chinese medicine, or eating animal blood and internal organs.
3. Bleeding: Be cautious of gastrointestinal bleeding. Gastrointestinal bleeding is a matter of concern. For adults, if the daily blood loss exceeds 5mL, the stool occult blood test will be positive, but the stool may still appear yellow visually. If the blood loss exceeds 50mL, black stool or tarry stool will appear. Black and loose stool may indicate increased blood loss. Peptic ulcer, esophageal-gastric variceal rupture, erosive gastritis, and gastric cancer are the main causes of gastrointestinal bleeding. If any issues arise, it is crucial to seek comprehensive examination and treatment at the hospital promptly to avoid delay in treatment.
