Blood in Stool: Causes and Concerns for Patients - Gastroenterology and Hepatology

Blood in stool can be a concerning symptom for many patients, and understanding its potential causes is crucial for proper management and treatment. In your case, it seems that you have been experiencing blood in your stool intermittently, which has been attributed to issues related to hemorrhoids (痔瘡) and possibly prolonged sitting. Let's delve into this further.


Causes of Blood in Stool
1. Hemorrhoids: These are swollen veins in the lower rectum or anus that can cause bleeding, especially during bowel movements. They can be internal or external, and symptoms may include bright red blood on the toilet paper or in the stool. Given your history of hemorrhoids, it is quite plausible that they are the source of the blood you are observing.

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

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon, can lead to diverticulitis, causing inflammation and bleeding.

4. Gastrointestinal Conditions: Other conditions such as inflammatory bowel disease (IBD), colorectal polyps, or even colorectal cancer can also cause blood in the stool, though these are less likely given your description.


Your Situation
You mentioned that your stools are soft and that you have been sitting for extended periods. Prolonged sitting can exacerbate hemorrhoids and lead to increased pressure in the rectal area, potentially causing or worsening bleeding. It is essential to address this lifestyle factor by incorporating more movement into your daily routine, which can help alleviate pressure on the rectal veins.


Management and Treatment
1. Lifestyle Modifications: Increasing your physical activity can help reduce the strain on your rectal area. Aim for regular exercise, and consider taking breaks to stand or walk if you have a sedentary job.

2. Dietary Changes: Ensure you are consuming a high-fiber diet to keep your stools soft and prevent straining during bowel movements. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Staying well-hydrated is also crucial.

3. Over-the-Counter Treatments: There are various over-the-counter treatments available for hemorrhoids, including topical creams and suppositories that can help reduce inflammation and discomfort.

4. Medical Evaluation: Since you have experienced blood in your stool for an extended period, it is advisable to follow up with your healthcare provider. They may recommend further evaluation, such as a colonoscopy, to rule out other potential causes of bleeding, especially if the bleeding persists or worsens.


Prognosis
Hemorrhoids can be a chronic issue, but with proper management, many patients find relief from symptoms. While hemorrhoids may not "go away" completely, they can often be managed effectively. If lifestyle changes and over-the-counter treatments do not provide relief, your doctor may discuss other options, including minimally invasive procedures or surgery.


Conclusion
In summary, while hemorrhoids are a common cause of blood in the stool, it is essential to monitor your symptoms closely. If you continue to experience blood in your stool, or if you notice any changes in your bowel habits, it is crucial to consult with your healthcare provider for a thorough evaluation. They can help determine the underlying cause and recommend appropriate treatment options tailored to your situation. Remember, early intervention can often prevent more severe complications down the line.
