Seeing red blood in your stool can be alarming and unsettling. While it's not a common occurrence, it's essential to understand that rectal bleeding can be caused by a variety of factors, ranging from mild to severe. As a medical professional with expertise in gastroenterology, I'll guide you through the possible causes, concerns, and what you should do if you experience this symptom.
The presence of red blood in stool, also known as hematochezia, can be a sign of an underlying condition that requires medical attention. The color and consistency of the blood can provide clues about the possible source of the bleeding. In some cases, the bleeding may be minor and self-limiting, while in others, it can be a sign of a more serious condition.
Causes of Rectal Bleeding
There are several possible causes of rectal bleeding, including:
- Anal fissures: Tears in the lining of the anus that can cause bleeding and pain
- Hemorrhoids: Swollen veins in the rectum or anus that can cause bleeding, itching, and discomfort
- Inflammatory bowel disease (IBD): Conditions like Crohn's disease and ulcerative colitis that cause inflammation and bleeding in the digestive tract
- Infections: Bacterial, viral, or parasitic infections that can cause inflammation and bleeding in the digestive tract
- Diverticulitis: Inflammation of small pouches in the wall of the colon that can cause bleeding and abdominal pain
- Cancer: Colorectal cancer, anal cancer, or other types of cancer that can cause rectal bleeding
Anal Fissures and Hemorrhoids
Anal fissures and hemorrhoids are two of the most common causes of rectal bleeding. Anal fissures are tears in the lining of the anus that can cause bleeding and pain, especially during bowel movements. Hemorrhoids, on the other hand, are swollen veins in the rectum or anus that can cause bleeding, itching, and discomfort.
According to the American Gastroenterological Association (AGA), hemorrhoids are a common condition that affects up to 75% of adults at some point in their lives. While they can be painful and uncomfortable, they are usually not a cause for concern. However, if you experience persistent or heavy bleeding, it's essential to seek medical attention to rule out other underlying conditions.
Inflammatory Bowel Disease (IBD) and Infections
Inflammatory bowel disease (IBD) and infections can also cause rectal bleeding. IBD, which includes conditions like Crohn's disease and ulcerative colitis, causes chronic inflammation and bleeding in the digestive tract. Infections, such as bacterial, viral, or parasitic infections, can also cause inflammation and bleeding in the digestive tract.
It's essential to note that IBD and infections can cause a range of symptoms, including diarrhea, abdominal pain, and weight loss. If you experience any of these symptoms, along with rectal bleeding, seek medical attention promptly.
| Cause | Symptoms |
|---|---|
| Anal fissures | Bleeding, pain, and discomfort during bowel movements |
| Hemorrhoids | Bleeding, itching, and discomfort |
| IBD | Diarrhea, abdominal pain, weight loss, and rectal bleeding |
| Infections | Diarrhea, abdominal pain, fever, and rectal bleeding |
