Abdominal pain, brown substance and blood in underwear

Doctor's answer:

It is recommended that you take probiotics such as Bifidumbacterium infantis, Yanshengliwei, and pancreatic enzymes (for digestion) to regulate your system. Avoid spicy and cold foods, as well as easily fermentable and gas-producing foods like milk and soy milk. Quit smoking and drinking alcohol, and pay attention to keeping your abdomen warm. Wishing you a speedy recovery.
