Blood in the stool for a period of time?


In the past few weeks, I have noticed blood in my stool.
This happened a few years ago but then stopped.
The blood appears on the surface of the stool and on the toilet paper, and it is bright red.
The stool itself is yellow-brown, occasionally a bit dark brown.
Last week, I visited a large hospital, and the doctor mentioned that it could be an anal fissure or hemorrhoids.
They prescribed a suppository and a hemorrhoid ointment, but after using the medication for a week, I am still seeing blood.
I am very concerned that there might be an issue with my health.
Thank you.

When it comes to the presence of blood in the stool, it can be a concerning symptom that warrants careful evaluation. The fact that you have experienced this symptom intermittently over the past few weeks, and that it has been noted on the surface of the stool or on toilet paper, suggests that it could be related to conditions affecting the lower gastrointestinal tract, particularly the rectum or anus.

Based on your description, the bright red blood you are observing is often indicative of bleeding from the lower gastrointestinal tract. Common causes of such bleeding include hemorrhoids (piles), anal fissures, diverticular disease, and in some cases, more serious conditions such as colorectal polyps or cancer. Given that your doctor has already suggested hemorrhoids or anal fissures as potential causes, it is important to consider the following:
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 pain, itching, and blood on the stool or toilet paper.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can be very painful and may also result in bright red blood.

3. Other Causes: While hemorrhoids and fissures are the most common causes of bright red blood in the stool, other conditions such as diverticulitis, inflammatory bowel disease (IBD), or colorectal cancer should not be ruled out, especially if the bleeding persists or is accompanied by other symptoms such as weight loss, changes in bowel habits, or abdominal pain.

Since you have been using the prescribed medications for a week without improvement, it is essential to follow up with your healthcare provider. Here are some steps you can take:
- Follow-Up Appointment: Schedule a follow-up appointment with your doctor to discuss your ongoing symptoms. It may be necessary to conduct further examinations, such as a colonoscopy, to visualize the interior of the colon and rectum and identify any underlying issues.

- Dietary Changes: Ensure you are consuming a high-fiber diet to help soften stools and reduce straining during bowel movements, which can exacerbate hemorrhoids and fissures. Staying hydrated is also crucial.

- Monitor Symptoms: Keep track of any additional symptoms that may arise, such as abdominal pain, changes in bowel habits, or weight loss. This information can be valuable for your healthcare provider.

- Seek Immediate Care: If you experience significant changes, such as increased bleeding, severe pain, or signs of anemia (such as dizziness or fatigue), seek medical attention promptly.

In conclusion, while hemorrhoids and anal fissures are common and often benign causes of blood in the stool, persistent symptoms warrant further investigation to rule out more serious conditions. It is crucial to maintain open communication with your healthcare provider and advocate for your health, especially if your symptoms do not improve with initial treatment.
