Blood in the stool during bowel movements?


Hello Doctor,
I would like to seek your advice.
Yesterday morning, I noticed blood during bowel movements, but since it was just before my menstrual period, I thought it was related to that and didn't think much of it.
However, this morning, I experienced the same situation again.
Upon closer observation, I found bright red blood on the toilet paper after wiping, and there seems to be bright red blood mixed in with the stool as well.
Over the past two weeks, my bowel movements have been relatively smooth, with only the front part of the stool being somewhat hard.
After the bowel movement, I now feel a slight pain around the anal area, possibly due to some friction.
Could this indicate the possibility of hemorrhoids, anal fissures, or even a more serious condition? I look forward to your response.
Thank you!

It is likely an anal fissure; medical treatment may include the use of stool softeners and topical ointments.

When it comes to the presence of blood in the stool, it is essential to approach the situation with caution and a clear understanding of potential causes and concerns. The symptoms you describe—bright red blood on toilet paper and mixed with stool—can indeed be indicative of several conditions, ranging from benign to more serious issues.

Firstly, the most common causes of bright red blood in the stool are hemorrhoids and anal fissures. Hemorrhoids are swollen veins in the lower rectum or anus that can cause bleeding, especially during bowel movements. They are often associated with straining during defecation, which can occur if the stool is hard or if there is constipation. Anal fissures, on the other hand, are small tears in the lining of the anus, often resulting from passing hard stools. Both conditions can cause pain and discomfort, particularly after bowel movements.

Given that you mentioned having slightly hard stools recently, it is plausible that either hemorrhoids or an anal fissure could be the cause of your symptoms. The bright red color of the blood typically suggests that the bleeding is coming from the lower gastrointestinal tract, such as the rectum or anus, rather than from higher up in the digestive system.

However, while hemorrhoids and fissures are common and often not serious, it is crucial to consider other potential causes of rectal bleeding. Conditions such as diverticular disease, colorectal polyps, or even colorectal cancer can also present with similar symptoms, particularly in individuals over the age of 50 or those with a family history of gastrointestinal diseases. Inflammatory bowel diseases (IBD) like Crohn's disease or ulcerative colitis may also cause rectal bleeding, along with other symptoms such as abdominal pain, diarrhea, or weight loss.

Given your symptoms and the fact that this is a recurring issue, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination, a digital rectal exam, and possibly further diagnostic tests such as a colonoscopy or imaging studies. These tests can help determine the exact cause of the bleeding and guide appropriate treatment.

In the meantime, there are some general measures you can take to alleviate discomfort and prevent further issues. Increasing your fiber intake through fruits, vegetables, and whole grains can help soften stools and reduce straining during bowel movements. Staying well-hydrated is also essential. If you suspect hemorrhoids, over-the-counter treatments such as topical creams or ointments may provide relief.

In summary, while your symptoms may suggest hemorrhoids or an anal fissure, it is essential to consult with a healthcare professional to rule out more serious conditions. Early diagnosis and treatment can significantly improve outcomes and alleviate discomfort. Remember, any new or unusual symptoms, especially those involving bleeding, should be taken seriously and evaluated by a medical professional.
