Noticing blood on your toilet paper or in the toilet after you poop could be caused by a variety of different things—and heading directly to a medical professional is always the best way to find out what’s what.
1. Ulcers are fairly common. For the majority of cases, treatment is relatively simple. Taking the right medication, reducing stress, cutting out alcohol, and nixing smoking can all help them heal. Darker, almost blackish blood typically comes from the upper GI tract (your stomach or esophagus), which could mean you have an ulcer.
2. Hemmorhoids commonly cause bright red blood on toilet paper or in the bowl. Hemorrhoids are scary because they bleed a lot.
3. an*l fissure, a tear that can be caused by anything from constipation to childbirth.
4. colorectal cancer.
The bottom line is, blood in the stool is never considered normal. So if you notice anything out of the ordinary, get your behind to a doctor right away.
