EGD is next.: People with cirrhosis can get varicose (dilated veins) within the esophagus which can bleed.  If the colonoscopy didn’t show anything then the next step should be EGD for a look at the esophagus.  Blood testing as well to see if you’re anemic and/or coagulopathic.

Accepted Answer

See your doc.: Problem sounds like it can be fixed. Very unlikely to be cancer.  Potential sources - hemorrhoids, diverticular disease, arteriovenous malformations, inflammatory bowel disease.  Sound like you need an exam. The fact that you have had colonoscopy at your young age means that someone has suspected something in the past. Time to follow up on that.
