/Blood in stool
Hello doctor, yesterday I noticed blood in my stool.
It seems like there might be a wound that caused it, as there was also blood on the toilet paper.
The blood is bright red, and my stool is normal.
I'm not sure if it was caused by straining too hard during a bowel movement the day before, as I did feel some pain in my anus at that time.
Could you please help me understand this? Thank you.

Dr. Cai Xingzhi reply Surgery
Hello: Your issue may be anal fissures, which can be caused by tight anal sphincter muscles.
Chronic constipation can lead to excessive straining during bowel movements, resulting in mucosal tears.
Please increase your vegetable intake and drink plenty of water.
If the problem persists, please consult a gastroenterologist to determine if surgical intervention is necessary.

More Info
When you notice blood in your stool, especially if it is bright red, it can be alarming. The presence of bright red blood typically indicates that the bleeding is occurring in the lower gastrointestinal tract, which includes the rectum and anus. Based on your description, it sounds like you may have experienced a minor injury or irritation, possibly due to straining during a bowel movement. This can lead to conditions such as hemorrhoids or anal fissures, both of which can cause bright red blood to appear on toilet paper or in the stool.
Common Causes of Blood in Stool:
1. Hemorrhoids: Swollen veins in the lower rectum or anus that can bleed during bowel movements, especially if you are straining.
2. Anal Fissures: Small tears in the lining of the anus that can occur from passing hard stools, leading to pain and bleeding.
3. Diverticular Disease: Small pouches that can form in the colon wall, which may bleed.
4. Colorectal Polyps or Cancer: While less common, these can also cause bleeding and should be ruled out, especially if the bleeding persists or is accompanied by other symptoms.
When to Seek Medical Help:
- If the bleeding continues or worsens.
- If you experience significant pain, especially if it is severe and does not improve.
- If you notice changes in your bowel habits, such as diarrhea or constipation that lasts more than a few days.
- If you experience symptoms like dizziness, weakness, or fainting, which could indicate significant blood loss.
- If you have a family history of gastrointestinal diseases, including colorectal cancer.
Self-Care and Prevention:
- Dietary Changes: Increasing fiber intake can help soften stools and reduce straining during bowel movements. Foods rich in fiber include fruits, vegetables, whole grains, and legumes.
- Hydration: Drinking plenty of fluids can also help prevent constipation.
- Avoid Straining: If you feel the urge to go, try not to delay the bowel movement, as this can lead to straining.
- Over-the-Counter Remedies: If hemorrhoids are suspected, topical treatments or sitz baths can provide relief.
Conclusion:
While it is possible that the blood you observed is due to a minor issue like hemorrhoids or an anal fissure, it is important to monitor your symptoms. If the bleeding persists or you have any concerns, it is advisable to consult a healthcare professional for a thorough evaluation. They may recommend a physical examination or further tests, such as a colonoscopy, to rule out more serious conditions. Remember, early detection and treatment are key to managing any gastrointestinal issues effectively.
