Is there a need to repeat the colonoscopy?


Hello Doctor, I had a colonoscopy in June 2016, during which a 0.3 cm polyp was removed, and the rest of the findings were normal.
It has been about five months since then.
Recently, in the past week, my stools have become very thin and harder to pass, although I am still having daily bowel movements and do not consider it constipation.
Could this be a sign that the polyp has regrown and is affecting the thickness of my stools? The more I think about it, the more worried I become.
Should I consider having another colonoscopy? Thank you.

Hello, sir.
Your symptom of having thinner stools is likely unrelated to small polyps and is more associated with poor colonic motility and a lack of fiber.
Please increase your intake of fruits and vegetables and follow up with your doctor.

When it comes to the question of whether you need another colonoscopy after polyp removal, there are several factors to consider. First, it's important to understand the nature of the polyp that was removed, as well as your overall risk factors for colorectal cancer.

In your case, you mentioned that a 0.3 cm polyp was removed during your last colonoscopy. Generally, small polyps, especially those that are benign (non-cancerous), do not typically lead to immediate concerns about recurrence. However, the fact that you are experiencing changes in your bowel habits, such as thinner stools, can be concerning and warrants further investigation.


Understanding Polyp Removal and Follow-Up
After the removal of a polyp, the standard recommendation is to have a follow-up colonoscopy within a certain timeframe, depending on the type and number of polyps found. For instance, if the polyp was adenomatous (a type that can develop into cancer), guidelines often suggest a follow-up colonoscopy in 3 to 5 years. If you had multiple polyps or if they were larger, the follow-up may be sooner. Since your polyp was small and presumably benign, your doctor may have recommended a longer interval before the next colonoscopy.


Symptoms and Their Implications
The change in your stool consistency could be due to various factors, including diet, hydration, and gastrointestinal motility. While it is less likely that a small polyp would cause such a change, it is essential to consider other possibilities, such as:
1. Dietary Changes: Increased fiber intake or changes in your diet can affect stool consistency.

2. Hydration: Dehydration can lead to harder stools, while adequate hydration typically results in softer stools.

3. Gastrointestinal Issues: Conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or even stress can lead to changes in bowel habits.


When to Seek Further Evaluation
Given your symptoms of thinner stools and difficulty in passing them, it is advisable to consult your healthcare provider. They may recommend another colonoscopy or other diagnostic tests, such as imaging studies or stool tests, to rule out any underlying conditions. While it is possible that the polyp could recur, it is more likely that your symptoms are related to other factors.


Conclusion
In summary, while the removal of a small polyp typically does not necessitate an immediate follow-up colonoscopy, your recent changes in bowel habits should be evaluated by a healthcare professional. They can assess your symptoms in the context of your medical history and determine the appropriate next steps. It is always better to err on the side of caution when it comes to gastrointestinal health, especially if you have concerns about potential recurrence or other underlying issues.
