Stomachache, brown stuff and blood in underwear

Patient's question:

Patient Gender: Male
Patient Age: 35
Abdominal pain, brown substance and blood in underwear

Doctor's answer:

It is recommended that you take probiotics such as Bifidumbacterium infantis, support vitality vitamins, and pancreatic enzymes (for digestion) to regulate your condition. Avoid spicy and cold foods, as well as easily fermentable and gas-producing foods like milk and soy milk in your daily diet. Quit smoking and alcohol, pay attention to keeping your abdomen warm, and wish you a speedy recovery.
