Abdominal pain, brown substance and blood in underwear

Doctor's answer:

It is recommended that you take probiotics such as Bifidumbacterium, Yanshengliwei, and pancreatin (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 in your daily diet. Quit smoking and drinking, pay attention to keeping your abdomen warm, and wish you a speedy recovery.
