Bleeding during bowel movements?


Hello doctor, I have been making changes to my lifestyle recently due to my gout.
I am overweight, so I have started exercising and making my own fruit juices.
However, yesterday when I went to the bathroom, I noticed a large amount of fresh blood, but the second time there was much less blood.
What could this be? Is it colon cancer? I have also been experiencing irregular bowel movements, having a bowel movement every 3-4 days.

Hello: If you experience constipation accompanied by blood in the stool, the majority of cases are due to anal fissures or hemorrhoids.
If the condition persists, it is advisable to consult a gastroenterologist or a colorectal specialist to rule out other possibilities, such as tumors or polyps.

When it comes to the presence of blood in your stool, it can understandably be a cause for concern, especially with your history of gout and recent lifestyle changes. Blood in the stool can arise from various conditions, some of which are benign while others may be more serious. It’s crucial to understand the potential causes and when to seek medical attention.

Firstly, the appearance of bright red blood in the stool often indicates that the source of bleeding is in the lower gastrointestinal tract, such as the rectum or anus. Common causes include hemorrhoids, anal fissures, or diverticular disease. Hemorrhoids, which are swollen veins in the rectal area, can cause bleeding during bowel movements, especially if you are straining due to constipation. Anal fissures, small tears in the lining of the anus, can also lead to bright red blood and are often associated with painful bowel movements.

On the other hand, if the blood is darker or mixed with the stool, it may suggest bleeding from higher up in the gastrointestinal tract, such as the stomach or small intestine. Conditions like peptic ulcers, gastritis, or even malignancies can cause this type of bleeding. Given your concern about colorectal cancer, it’s important to note that while blood in the stool can be a symptom of cancer, it is not the only indicator, and many other conditions can cause similar symptoms.

Your mention of having infrequent bowel movements (every 3-4 days) could also be contributing to the issue. Constipation can lead to straining during bowel movements, which increases the risk of developing hemorrhoids or fissures. It’s essential to maintain a healthy diet rich in fiber, stay hydrated, and engage in regular physical activity to promote regular bowel movements.

Given your symptoms, here are some steps you should consider:
1. Consult a Healthcare Provider: It’s crucial to discuss your symptoms with a healthcare professional. They may recommend a physical examination and possibly a colonoscopy to investigate the source of the bleeding.

2. Dietary Changes: Incorporate more fiber into your diet through fruits, vegetables, whole grains, and legumes. This can help alleviate constipation and reduce straining during bowel movements.

3. Hydration: Ensure you are drinking enough fluids, as this can help soften your stool and promote regular bowel movements.

4. Monitor Symptoms: Keep track of any additional symptoms, such as changes in bowel habits, abdominal pain, weight loss, or fatigue, and report these to your doctor.

5. Avoid Straining: If you are experiencing constipation, consider using over-the-counter stool softeners or laxatives as recommended by your healthcare provider.

While the presence of blood in your stool can be alarming, it is essential to approach the situation calmly and seek medical advice. Early diagnosis and treatment can significantly improve outcomes, especially if there is an underlying condition that needs to be addressed. Remember, not all cases of blood in the stool are indicative of cancer, but it is always best to err on the side of caution and get a professional evaluation.
