Hello friend,
With the question “What is the sign of the disease? ", the doctor would like to answer as follows:
You should take your husband for an early gastroscopy and colonoscopy, because dark brown bowel movements can be caused by damage to the stomach causing bleeding. Depending on the damage to the stomach or colon, there will be different treatments. It could also be just a digestive disorder due to food
If you still have questions about abdominal pain and black brown oil scum, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
