Suspected blood in stool, with a change in caliber?


I have been sitting on the toilet for extended periods (about a year) and often straining excessively.
Recently, I noticed that my stools have become thin, about 2-3 centimeters wide, and there are many strands.
I also found what appears to be red streaks resembling blood in my stool.
When wiping, the toilet paper often has mucus on it.
I frequently feel the urge to have a bowel movement, and I experience soreness and numbness around the anal area.
I would appreciate it if a doctor could take the time to respond.
Thank you.

Hello Mr.
Xiao Guang, if you are still experiencing red stools, you can take a picture of the stool with the red discoloration and show it to your doctor.
Additionally, if you continue to notice mucus in your stools, you may want to arrange for a routine stool examination at the hospital.
Thank you for your inquiry.

More Info


Understanding changes in stool, especially when accompanied by symptoms like blood, narrowing, and discomfort, can be concerning. Based on your description, it appears that you are experiencing several gastrointestinal issues that warrant further investigation.

Firstly, the narrowing of your stool to about 2-3 centimeters in diameter, especially if it has become consistently thin, can be a sign of a potential obstruction or narrowing in the colon. This could be due to various reasons, including but not limited to, inflammation, strictures, or even tumors. In your case, given your history of prolonged straining during bowel movements, it is possible that you may have developed hemorrhoids or anal fissures, which can also contribute to the symptoms you're experiencing.

The presence of red streaks or blood in your stool is particularly concerning. While it could be related to hemorrhoids, which often cause bright red blood due to irritation and inflammation, it is essential to rule out other causes. Blood in the stool can also indicate more serious conditions, such as diverticulitis, inflammatory bowel disease (IBD), or even colorectal cancer, especially if you are experiencing other symptoms like significant changes in bowel habits, weight loss, or persistent abdominal pain.

The mucus you mentioned on the toilet paper can also be indicative of several conditions. Mucus in the stool can occur with conditions like irritable bowel syndrome (IBS), infections, or inflammatory bowel diseases. It is important to note that while some mucus is normal, an increase in mucus production, especially when accompanied by other symptoms, should be evaluated by a healthcare professional.

Given your symptoms, it is crucial to seek medical attention. A healthcare provider may recommend a thorough evaluation, which could include a physical examination, a digital rectal exam, and possibly imaging studies or a colonoscopy. A colonoscopy is particularly useful for visualizing the interior of the colon and rectum and can help identify any abnormalities, such as polyps, tumors, or areas of inflammation.

In the meantime, consider the following recommendations:
1. Dietary Changes: Ensure you are consuming a high-fiber diet to help regulate your bowel movements and reduce straining. Foods rich in fiber include fruits, vegetables, whole grains, and legumes.

2. Hydration: Drink plenty of water to help soften your stool and promote regular bowel movements.

3. Avoid Straining: Try to avoid prolonged sitting on the toilet and straining during bowel movements, as this can exacerbate hemorrhoids and lead to further complications.

4. Monitor Symptoms: Keep track of any changes in your symptoms, including the frequency of blood in your stool, changes in bowel habits, or any new symptoms that may arise.

5. Seek Medical Attention: Given the potential seriousness of your symptoms, it is advisable to consult with a healthcare provider as soon as possible for a comprehensive evaluation and appropriate management.

In conclusion, while some of your symptoms may be related to benign conditions like hemorrhoids or IBS, the presence of blood and changes in stool caliber should not be ignored. A thorough evaluation by a healthcare professional is essential to determine the underlying cause and to ensure appropriate treatment.
