Blood During Bowel Movements: Causes and Concerns Explained

Blood in the stool during bowel movements?

Hello, Doctor: I have a question for you.
Recently, I have noticed blood when wiping after bowel movements, and on two occasions, including today, I have seen small blood clots during defecation.
The blood clot from two days ago was slightly dark red, while today's was a brighter red.
A while ago, I experienced some itching around the anus, but that has resolved.
Additionally, I had a problem with hyperthyroidism two years ago, for which I had blood tests and subsequently saw a doctor and took medication.
After another blood test, my levels were within the normal range.
However, I still frequently experience palpitations and sometimes feel quite uncomfortable; it eventually subsides after a while.
Occasionally, I also feel a sensation of tightness in my chest, and deep breathing does not provide relief.

Dr. Liu Jianting reply Urology

I have been defeated by you, and it's indeed inconvenient for a urologist to answer your questions.
However, I still want to provide you with some advice.
The presence of blood clots in your stool, whether dark red or bright red, indicates that the bleeding is likely from the rectum or anus.
The chance of a young person having "serious issues" is quite low; most cases are likely due to hemorrhoids.
I recommend that you consult a colorectal surgeon for a thorough examination.
As for the issue of hyperthyroidism, it would be best for you to regularly return to the hospital to see the physician who initially treated you or consult an endocrinologist for follow-up evaluations.

More Info

When experiencing blood during bowel movements, it is essential to understand the potential causes and the necessary steps to address the issue. The presence of blood in the stool can be alarming and may indicate various underlying conditions, ranging from benign to more serious health concerns.

The blood you observed during bowel movements, particularly if it appears as small clots and varies in color from dark red to bright red, can be attributed to several common causes. One of the most frequent reasons for blood in the stool is hemorrhoids, which are swollen blood vessels in the rectal area that can bleed during bowel movements, especially if there is straining involved. The itching you mentioned around the anus could also suggest hemorrhoids or anal fissures, which are small tears in the lining of the anus that can occur due to hard stools or excessive straining.

Another possible cause could be diverticular disease, where small pouches form in the colon wall and can become inflamed or bleed. In some cases, gastrointestinal conditions such as inflammatory bowel disease (IBD), including Crohn's disease or ulcerative colitis, can also lead to blood in the stool. These conditions often present with additional symptoms such as abdominal pain, diarrhea, and weight loss.

Given your history of hyperthyroidism and ongoing symptoms like palpitations and chest discomfort, it is crucial to consider that these symptoms may not be directly related to the blood in your stool. However, they warrant attention. Hyperthyroidism can lead to increased heart rate and anxiety, which might explain your palpitations and feelings of discomfort. It is essential to follow up with your healthcare provider to ensure that your thyroid levels remain stable and to rule out any other potential cardiovascular issues.

In terms of addressing the blood during bowel movements, it is advisable to seek medical evaluation. A healthcare professional may recommend a physical examination, including a rectal exam, and possibly further diagnostic tests such as a colonoscopy, especially if the bleeding persists or is accompanied by other concerning symptoms like significant abdominal pain, changes in bowel habits, or weight loss.

In the meantime, to alleviate symptoms associated with hemorrhoids or anal fissures, consider the following measures:
1. Increase Fiber Intake: Consuming a diet rich in fiber can help soften stools and reduce straining during bowel movements. Foods high in fiber include fruits, vegetables, whole grains, and legumes.

2. Stay Hydrated: Drinking plenty of water can also help prevent constipation and promote regular bowel movements.

3. Warm Baths: Soaking in a warm bath can provide relief from discomfort and help reduce itching or irritation.

4. Over-the-Counter Treatments: There are various topical treatments available for hemorrhoids that can help alleviate symptoms.

In conclusion, while the presence of blood during bowel movements can be concerning, many causes are treatable. It is essential to consult with a healthcare provider to determine the underlying cause and appropriate management. Additionally, addressing your ongoing symptoms related to hyperthyroidism and ensuring your overall cardiovascular health is equally important. Regular follow-ups and open communication with your healthcare provider will help you manage these health concerns effectively.
