Colonoscopy

Hello Doctor, I underwent a colonoscopy on the 17th of this month.
On the same day, I experienced bleeding from internal hemorrhoids due to frequent bowel movements, but it did not affect the examination.
After the procedure, I was informed that a biopsy would be performed, and I am awaiting the follow-up appointment.
The day after the examination, I noticed that after bowel movements, there was some dark grayish stool, although it was not a large amount.
This continued for the next few days.
Additionally, I observed that the color of my stool was brown with some blackish hues, but it was not consistently dark, and there was no significant abdominal pain.
When I do experience abdominal pain, it usually subsides significantly after a bowel movement.

Could this indicate internal bleeding? I had an upper endoscopy last month, which showed only mild inflammation and gastroesophageal reflux.
I am quite worried and scared, wondering if there is a possibility of bleeding after the colon biopsy.
I am unsure how severe internal bleeding pain can be; I only occasionally feel discomfort in my abdomen.
I would appreciate your analysis, as my child is currently hospitalized, and I have no one to help me find time to see a doctor.
I am really struggling while waiting for my follow-up appointment.
Thank you for your help and analysis.
I appreciate it.

More Info

After undergoing a colonoscopy, it is not uncommon for patients to experience some degree of bleeding, especially if biopsies were taken during the procedure. The symptoms you describe, including the presence of dark or blackish stools, can be concerning, but they do not always indicate a serious problem.

Understanding Post-Colonoscopy Bleeding
1. Normal Post-Procedure Symptoms:
- After a colonoscopy, it is typical to have some mild bleeding, particularly if biopsies were performed. The bleeding usually arises from the biopsy sites and should be minimal.
- It is also common to experience changes in bowel movements, including the passage of darker stools, which can occur due to the presence of blood that has been digested or due to the effects of the procedure itself.

2. Color of Stools:
- The presence of black or dark stools (melena) can indicate that there is blood that has been digested, which typically suggests bleeding from the upper gastrointestinal tract. However, if you have had a colonoscopy recently, it may also be related to the procedure itself, especially if there was any bleeding from the biopsy sites.

- Coffee ground-like stools can also be a sign of bleeding, but if the stools are only slightly darker and not consistently black, it may not be a cause for alarm.

3. When to Worry:
- If you experience significant bleeding (more than a small amount), or if the bleeding persists for more than a few days, it is important to seek medical attention.

- Other concerning symptoms include severe abdominal pain, dizziness, or fainting, which could indicate a more serious issue such as significant internal bleeding.

4. Abdominal Discomfort:
- Mild abdominal discomfort after a colonoscopy is common and can be due to gas or irritation from the procedure. However, if the discomfort worsens or is accompanied by severe pain, it is advisable to consult a healthcare professional.

5. Follow-Up Care:
- Since you are awaiting a follow-up appointment, it is essential to monitor your symptoms closely. Keep track of any changes in your bowel habits, the presence of blood, and any abdominal pain. If your symptoms worsen, do not hesitate to seek immediate medical care, even if it means going to an emergency room.

6. Potential Causes of Your Symptoms:
- Given your history of hemorrhoids, it is possible that the bleeding you experienced could be related to that condition rather than the colonoscopy itself. Hemorrhoids can cause bleeding, especially after straining during bowel movements.

- The dark stools could also be a result of dietary factors or medications you may be taking, such as iron supplements, which can darken stool color.

Conclusion
In summary, while some bleeding and changes in stool color can be expected after a colonoscopy, it is crucial to remain vigilant about your symptoms. If you notice significant changes or worsening symptoms, it is important to seek medical attention promptly. Your health and peace of mind are paramount, especially during a stressful time. If you have any doubts or concerns, do not hesitate to reach out to a healthcare provider for guidance.
