Been having bloody stools for the past 2 days, i've have had bloody stools before but for days in a row. i'm on antacids maybe if that affects it.

Always abnormal: Does not seem to come from an ulcer because the stools are not black. See a gastroenterologist.

Not normal, get help: Blood in stool is a warning sign. Brisk bleeding warrants emergency care. Causes of bleeding may be predictable (e.G rectal trauma), but evaluation is always appropriate. A rule of thumb (but not absolute): black stool means bleeding comes from upper GI tract; grape jelly stool from small bowel; silver stool from biliary tree; burgundy stool from right colon; red blood from left colon to anus.

Bloody stool: You are on Omeprazole and having bloody stools. Please see you doctor for your thorough physical examination specially anal hemorrhoids, fissure, fistula. If bleeding is heavy, please go to er. At your age colitis is also possibility, thanks.
