Soft stools with bleeding?


Hello, doctor.
I have a history of gastrointestinal issues.
Recently, I experienced symptoms similar to gastroenteritis, with vomiting and diarrhea.
I saw a doctor, finished my medication, and have not vomited since.
However, I have had soft stools for four to five consecutive days, and today, after feeling like I was done, I noticed some bright red blood when I strained a bit more.
Why is this happening? Normally, my bowel movements are quite smooth, but occasionally when I have harder stools, I notice a little blood when wiping, along with a painful sensation that feels like a tear.
Could this be due to polyps?

Dr. Chen Qifeng reply Gastroenterology and Hepatology


Hello: During constipation or diarrhea, the pressure or contraction near the anal area often leads to hemorrhoidal bleeding.
Of course, whether there are other lesions in the rectal or anal area may require further examination with a sigmoidoscopy or colonoscopy if necessary.
Wishing you health, Dr.

When it comes to the presence of blood in soft stool, there are several potential causes and concerns that need to be addressed. The fact that you have a history of gastrointestinal issues, including a recent episode of gastroenteritis, may play a significant role in your current symptoms.
Firstly, the appearance of bright red blood in your stool can be alarming, but it is essential to understand that it often indicates bleeding from the lower gastrointestinal tract. This could be due to several reasons, including hemorrhoids, anal fissures, diverticular disease, or even more serious conditions like colorectal polyps or cancer. Given your mention of experiencing pain and slight bleeding when passing hard stools, it is quite possible that you may have developed anal fissures. These are small tears in the lining of the anus that can occur due to straining during bowel movements, especially when passing hard stools. They can cause sharp pain and bleeding, typically bright red in color, which is consistent with what you are experiencing.

Another possibility is hemorrhoids, which are swollen blood vessels in the rectal area that can bleed, especially during bowel movements. They can also cause discomfort and a sensation of fullness or pressure. If you have been experiencing soft stools for several days, it is possible that the straining associated with bowel movements could have exacerbated any existing hemorrhoids or fissures.

While less common, the presence of blood in stool can also be associated with more serious conditions such as colorectal polyps or cancer, particularly if you have risk factors such as a family history of colorectal cancer, age over 50, or other gastrointestinal symptoms. Given your history of gastrointestinal issues, it is prudent to consider these possibilities as well.

In terms of management, it is crucial to address the underlying causes of your symptoms. Here are some steps you can take:
1. Dietary Changes: Incorporate a high-fiber diet to help soften your stools and reduce straining during bowel movements. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Staying well-hydrated is also essential.

2. Over-the-Counter Remedies: You may consider using stool softeners or fiber supplements to help ease bowel movements. If hemorrhoids are suspected, topical treatments may provide relief.

3. Avoid Straining: Try to avoid straining during bowel movements. If you feel the urge to go, do so promptly rather than holding it in.

4. Seek Medical Attention: Given the presence of blood in your stool, it is advisable to consult a healthcare professional for a thorough evaluation. They may recommend a physical examination, and possibly a colonoscopy, to rule out any serious conditions and to assess the health of your gastrointestinal tract.

5. Monitor Symptoms: Keep track of any additional symptoms such as changes in bowel habits, abdominal pain, weight loss, or changes in appetite, and report these to your healthcare provider.

In summary, while the presence of blood in your stool can be concerning, it is often related to benign conditions such as hemorrhoids or anal fissures, especially in the context of recent gastrointestinal distress. However, it is essential to seek medical advice to rule out more serious conditions and to receive appropriate treatment. Your health and well-being should always be a priority, and addressing these symptoms early can lead to better outcomes.
