Blood in the stool?


Hello, doctor.
I have had a cold for the past couple of days and have been taking cold medication.
My bowel habits have changed; I hadn't had a bowel movement for a day and a half before yesterday.
When I did have a bowel movement yesterday, I noticed that the stool was in small pieces, some of which had streaks of blood on them.
This morning, the stool was similarly in small pieces and also had blood streaks, and I felt a little bit of bright red blood when wiping.
Previously, I sometimes noticed clear mucus with my stool, and sometimes I didn't.
Could this indicate a gastrointestinal issue? My mental state hasn't been significantly affected, but seeing the blood makes me quite anxious.

This situation likely indicates a higher possibility of hemorrhoidal bleeding.
As long as there is no further bleeding, it should not be a concern.
It is recommended to avoid constipation during this period and to shorten the time spent on bowel movements.
Warm sitz baths may also help alleviate symptoms.
You can purchase over-the-counter hemorrhoidal suppositories for use.
It is best not to take stool softeners indiscriminately; at this age, increasing dietary fiber and fluid intake should be sufficient.
If bleeding persists, it is advisable to consult a physician for evaluation.

More Info


Blood-streaked stool can be alarming, and it’s understandable that you’re feeling anxious about it. There are several potential causes for blood in the stool, and while some may be benign, others could indicate a more serious condition. Given your recent changes in bowel habits and the presence of blood, it’s important to consider a few possibilities.

1. Hemorrhoids: One of the most common causes of blood-streaked stool is hemorrhoids, which are swollen veins in the lower rectum or anus. They can cause bright red blood on the surface of the stool or on toilet paper. If you’ve been experiencing constipation, straining during bowel movements can exacerbate hemorrhoids.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to sharp pain during bowel movements and may also cause bleeding.

3. Diverticular Disease: Diverticulosis involves the formation of small pouches in the colon wall, which can sometimes become inflamed or infected (diverticulitis). This condition can lead to bleeding and changes in bowel habits.

4. Gastrointestinal Infections: Certain infections can cause inflammation in the intestines, leading to symptoms like diarrhea, abdominal pain, and blood in the stool. This could be related to a viral or bacterial infection, especially if you’ve had gastrointestinal symptoms.

5. Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease or ulcerative colitis can cause inflammation in the gastrointestinal tract, leading to symptoms such as diarrhea, abdominal pain, and blood in the stool. The presence of mucus, as you mentioned, can also be associated with these conditions.

6. Polyps or Colorectal Cancer: While less common, polyps in the colon can bleed, and in some cases, they can be precursors to colorectal cancer. If you are experiencing persistent blood in your stool, especially if you have other symptoms like weight loss or changes in appetite, it’s essential to consult a healthcare provider.

Given that you’ve recently experienced changes in your bowel habits, including constipation and the presence of blood, it’s advisable to seek medical attention. A healthcare provider may recommend a physical examination, possibly a digital rectal exam, and further diagnostic tests such as a colonoscopy, especially if the symptoms persist or worsen.

In the meantime, here are some general tips to help manage your symptoms:
- Stay Hydrated: Drink plenty of fluids to help soften your stool and prevent constipation.

- Dietary Changes: Incorporate more fiber into your diet through fruits, vegetables, and whole grains to promote regular bowel movements.

- Avoid Straining: If you feel the urge to go, try not to delay it, and avoid straining during bowel movements.

It’s good to hear that your overall mental state hasn’t been significantly affected, but it’s important to address any physical symptoms that cause concern. Blood in the stool should always be evaluated by a healthcare professional to rule out any serious conditions and to provide appropriate treatment if necessary. Don’t hesitate to reach out to your doctor for a thorough evaluation and peace of mind.
