Seeing blood in your stool can be scary. You may worry it signals a serious health issue. The truth is, many things can cause rectal bleeding—and not all of them are dangerous. In this friendly guide, we’ll explain the causes of blood in stool without pain, when to worry about blood in stool, what blood in your stool says about your health, and how rectal bleeding is diagnosed. We’ll also share tips from Dr. Bharat Pothuri of Gastrodoxs in Houston so you know exactly when to call your doctor.
Rectal bleeding is any blood that comes from your lower digestive tract. You might notice bright red drops on toilet paper or darker, tar-like stool.

Your doctor will first take a thorough history and exam. Then, tests may include:
| Test | What It Is | Pros | Cons |
| Digital Rectal Exam | Doctor feels rectum with gloved finger | Quick, no prep | Limited view beyond the rectum |
| Fecal Occult Blood Test | Checks stool for hidden blood | Noninvasive, home sample | Can miss intermittent bleeding |
| Colonoscopy | Camera examines entire colon | Gold standard, can remove polyps | Bowel prep, sedation required |
| Flexible Sigmoidoscopy | Camera examines lower colon | Less prep, no full sedation needed | Limited to rectum and sigmoid colon |
| Anoscopy/Proctoscopy | Short scope for rectum/anus | Quick, no sedation | Doesn’t view higher colon areas |
Treatment depends on the cause. General approaches include:
