Black loose stools are considered to be caused by dietary factors, but may also be caused by drug factors or cirrhosis of the liver, peptic ulcer and other disease factors.
1. Dietary factors: Eating some iron-rich foods, such as green leafy vegetables, can lead to black stools.
2. Drug factors: taking iron, bismuth can also cause black loose stools; taking aspirin and other non-steroidal anti-inflammatory drugs can cause gastrointestinal bleeding adverse reactions, followed by black loose stools.
3. Disease factors: peptic ulcer, cirrhosis and other diseases can cause upper gastrointestinal bleeding resulting in black stools.
If you have black loose stools, we recommend that you go to the hospital and ask the doctor to make a judgment, rather than making a blind judgment on your own.
