Rectal bleeding


Hello Doctor, I have been experiencing bleeding during bowel movements lately.
My stools are very hard, and the discomfort during defecation often leads to bleeding.
I usually eat vegetables and fruits, and I also drink yogurt to help with bowel movements, but it doesn't seem to be effective.
This has been going on for a while.
Why is this happening? I hope you can give me some advice.
Thank you!

Hello, hard stools and blood in the stool can have many causes, including dietary factors (such as insufficient water intake and low fiber consumption), structural issues in the colon and rectum (including hernias, intussusception, diverticula, polyps, tumors, fistulas, inflammation, or functional bowel problems), as well as other endocrine disorders, medications, and mental health conditions.
I recommend maintaining good habits, such as drinking plenty of water, eating more fruits and vegetables, establishing a regular bowel movement routine, and engaging in appropriate physical activity.
If there is no improvement, you may consider seeking pharmacological treatment.
Additionally, if you frequently experience bleeding, be aware of the possibility of anemia and check for rectal fistulas or other lesions.
Sincerely, Dr.
Lin Ming-Hui, Internal Medicine.

Experiencing blood in your stool can be alarming and is often a sign that something is not quite right in your gastrointestinal (GI) tract. There are several potential causes for this symptom, and understanding them can help you take appropriate action.

One of the most common reasons for blood in the stool, especially if you are experiencing hard stools and discomfort during bowel movements, is hemorrhoids. Hemorrhoids are swollen veins in the lower rectum and anus that can become inflamed and bleed, particularly when straining during bowel movements. This is often exacerbated by constipation, which can lead to hard stools that are difficult to pass. When you have to exert more force to have a bowel movement, it can cause these veins to rupture, resulting in bright red blood on the toilet paper or in the stool.

Another possible cause of blood in the stool is anal fissures, which are small tears in the lining of the anus. These can occur due to passing hard stools and can be quite painful, often leading to bleeding during or after a bowel movement. The pain associated with fissures can make you hesitant to have a bowel movement, which can further complicate the issue by leading to constipation.

In some cases, blood in the stool can indicate more serious conditions, such as diverticulosis, inflammatory bowel disease (IBD) like Crohn's disease or ulcerative colitis, or even colorectal cancer. These conditions often present with additional symptoms such as abdominal pain, changes in bowel habits, weight loss, or fatigue. If you notice any of these symptoms alongside the blood in your stool, it is crucial to seek medical attention promptly.

Given your situation, where you have been experiencing hard stools and blood during bowel movements despite consuming fruits, vegetables, and probiotics, it may be beneficial to focus on increasing your fiber intake further. Fiber helps to soften stools and promote regular bowel movements. You might consider incorporating more whole grains, legumes, and a variety of fruits and vegetables into your diet. Additionally, staying well-hydrated is essential, as adequate fluid intake can help prevent constipation.

If dietary changes do not alleviate your symptoms, or if the bleeding persists, it is important to consult with a healthcare professional. They may recommend a physical examination, and possibly further diagnostic tests such as a colonoscopy, to determine the underlying cause of your symptoms.
In the meantime, here are some practical tips to help manage your symptoms:
1. Increase Fiber Intake: Aim for a balanced diet rich in fiber. Foods like oats, beans, lentils, fruits, and vegetables can help.

2. Stay Hydrated: Drink plenty of water throughout the day to help soften your stools.

3. Avoid Straining: When you feel the urge to go, try not to delay. Straining can worsen hemorrhoids and fissures.

4. Use Moist Wipes: Instead of toilet paper, consider using moist wipes to reduce irritation around the anal area.

5. Warm Baths: Soaking in a warm bath can help soothe discomfort and promote relaxation of the anal muscles.

6. Over-the-Counter Remedies: If you suspect hemorrhoids, topical treatments or suppositories may provide relief.

7. Consult a Doctor: If symptoms persist or worsen, seek medical advice to rule out more serious conditions.

In summary, while blood in the stool can often be attributed to benign causes like hemorrhoids or fissures, it is essential to monitor your symptoms closely and consult a healthcare provider if you have any concerns. Early intervention can lead to better outcomes and peace of mind regarding your gastrointestinal health.
