Discovering blood in your stool can be alarming. While it’s a topic many find uncomfortable to discuss, it’s crucial to understand that rectal bleeding is a symptom that warrants attention. Though cancer is a significant concern for many, blood in your stool can arise from various, often less serious, conditions. As Dr. David Richards, a gastroenterologist, explains, identifying the cause is essential for your health.
Diverse Causes of Blood in Your Stool
Several conditions can lead to blood in your stool. Hemorrhoids, which are swollen veins in the rectum and anus, are a frequent culprit. Other potential causes include:
- Rectal prolapse
- Rectal polyps
- Ulcers in the rectum
- Injury to the colorectal mucosa (lining)
- Anal fissures (small tears in the anus lining)
- Diverticular bleeding (bleeding from small pouches in the colon)
- Inflammatory Bowel Diseases (IBD) like ulcerative colitis and Crohn’s disease
- Colorectal cancer

Dr. Richards points out the connection to bowel habits: “Conditions like hemorrhoids, fissures, or prolapse can be triggered by constipation and straining during bowel movements. Conversely, they can also be associated with frequent loose stools.”
Determining the Root Cause: The Importance of Medical Examination
Despite the numerous potential causes of rectal bleeding, accurately diagnosing the issue necessitates a professional medical evaluation. This typically involves a rectal exam and a colonoscopy.
“The diagnostic approach is quite direct: we need to examine both the exterior and interior,” Dr. Richards states. He emphasizes the increasing incidence of colorectal cancer in younger individuals, making a thorough examination even more critical. “Considering the data showing a rise in colorectal cancer among younger adults, many physicians, including myself, advocate for a colonoscopy. I understand it’s not a preferred procedure, but my priority is to ensure nothing serious is overlooked.”
A colonoscopy allows for a complete visualization of the large intestine (colon) and rectum. The procedure is performed under sedation and requires bowel preparation, usually involving a laxative solution to cleanse the colon.

“While colonoscopies might not be enjoyable, most patients tolerate them well. The procedure itself is relatively quick, and recovery is generally short,” assures Dr. Richards. He also highlights the preventative aspect: “For individuals aged 45 and older, a colonoscopy every 10 years is recommended as a screening measure, even without symptoms. For those under 45 experiencing rectal bleeding, I recommend it to definitively understand the situation. Uncertainty is something I prefer to avoid in these cases.”
Understanding the Appearance of Blood in Stool: Clues for Diagnosis
The appearance of blood in your stool can offer valuable clues about its origin within your digestive system, which can extend up to 30 feet and includes the esophagus, stomach, and intestines. Describing the blood’s characteristics to your doctor is helpful in pinpointing the problem.
“Bright red blood often suggests a source lower in the colon or rectum, possibly diverticular bleeding or hemorrhoids. Darker blood might indicate a source higher up in the colon,” explains Dr. Richards. “If the blood appears black and tarry, this could signal an issue in the small intestine or stomach.”
Blood only noticed on toilet paper after wiping is frequently associated with hemorrhoids or anal fissures but still requires medical confirmation.
Blood from polyps or colorectal cancer can manifest in various ways. Polyps or tumors located low in the rectum may present with bright red blood, mimicking hemorrhoids. Conversely, slow-bleeding tumors in the initial part of the colon might result in dark red or black stools. In some cases, tumors may bleed microscopically, causing only a subtle darkening of the stool or no visible color change at all.
The Significance of Intermittent Rectal Bleeding
Rectal bleeding that occurs sporadically should not be dismissed.
“It’s understandable to feel hesitant about discussing rectal bleeding, leading some to wait and see if it resolves on its own,” Dr. Richards acknowledges. “However, cancers can bleed intermittently, stopping and starting. Therefore, it’s crucial not to delay seeking medical advice simply because the bleeding has stopped.”
Accompanying Symptoms: Important Indicators
Pay attention to any additional symptoms accompanying rectal bleeding. These can provide further insights and should be discussed with your doctor.
The following symptoms, in conjunction with rectal bleeding, may indicate a more serious underlying issue:
- Anemia and/or lightheadedness
- Chest pain and shortness of breath
- Abdominal, pelvic, or rectal pain
- Fevers
- Nausea and vomiting
- Difficulty swallowing or pain while swallowing
- Jaundice (yellowing of the skin and eyes)
- Unexplained and significant weight loss

Listen to Your Body: Early Detection is Key
Dr. Richards emphasizes that many health problems can develop without initial symptoms. The appearance of symptoms is a signal that needs to be taken seriously.
“We know that some individuals with colorectal cancer experience no symptoms at all initially,” Dr. Richards concludes. “If you observe blood in your stool, your body is communicating something important. Don’t ignore it. Seek medical advice to understand Why Am I Defecating Blood and ensure your health.”
For medical consultation regarding rectal bleeding, please consult your physician or a qualified healthcare provider.
