Post-Surgery Constipation: Recovery After Hemorrhoid Surgery - Surgery

Post-hemorrhoid surgery


Hello Dr.
Chang, I am a patient with grade III internal hemorrhoids and have already undergone minimally invasive hemorrhoid surgery.
It has been over two months since the surgery.
For the first month after the surgery, my bowel movements were normal, but around the two-month mark, I suddenly experienced constipation.
I have been consuming vegetables, fruits, water, and probiotics, but I feel like I have difficulty passing stool and need to go several times before I can finally do so.
I am wondering if the medications I took post-surgery to aid bowel movements have caused my gastrointestinal motility to slow down.
Three doctors at a major hospital have all said that there is no issue with anal stenosis and that my surgical site is healing well.
I am still puzzled about where the problem lies.
I have already undergone both colonoscopy and gastroscopy; during the colonoscopy, two polyps were removed, and the gastroscopy results were normal.
Currently, I am relying on traditional Chinese medicine to help with bowel movements.
Is my bowel issue related to the fact that the colorectal surgical site has not fully healed, or do I need to undergo a rectal pressure test? I have heard that after a colonoscopy, the anal area may feel weaker.
I did not have any issues with constipation before the surgery; this situation only arose after the operation.

If the examination shows no issues with stenosis, it may not necessarily be related to surgery.
A colonoscopy will not affect bowel function.
It is advisable to increase fluid intake and fiber supplements, engage in more physical activity to promote gastrointestinal motility, use stool softeners temporarily, and have regular follow-up appointments to monitor the wound and adjust medications as needed.

Post-surgery constipation, especially following hemorrhoid surgery, can be a frustrating and uncomfortable experience. It's important to understand that while surgery can alleviate the symptoms of hemorrhoids, it can also lead to temporary changes in bowel habits and gastrointestinal function.
In your case, it seems that you initially had normal bowel movements after your surgery, but then began experiencing constipation around the two-month mark. This could be attributed to several factors. First, the surgical procedure itself can sometimes alter the normal functioning of the bowel. Even minimally invasive techniques can lead to temporary changes in bowel motility due to inflammation or changes in the nerve supply to the area.
Additionally, medications prescribed post-surgery, particularly opioids for pain management, can significantly slow down bowel motility, leading to constipation. Even if you are no longer taking these medications, the effects on your bowel function can sometimes persist for a while.
You mentioned that you have been consuming a diet rich in fruits, vegetables, and fluids, which is excellent for promoting bowel health. However, if your bowel movements are still infrequent or difficult, it may be beneficial to consider other factors that could be contributing to your constipation. Stress and anxiety can also play a role in bowel function, as can changes in your daily routine or physical activity levels post-surgery.

The fact that you have undergone both a colonoscopy and an upper endoscopy is reassuring, as these tests can help rule out other potential causes of your symptoms, such as structural abnormalities or other gastrointestinal issues. The removal of polyps during the colonoscopy is also a positive step towards maintaining your colorectal health.

Regarding your question about whether the rectal pressure testing or other diagnostic evaluations are necessary, it may be worth discussing with your healthcare provider. If your symptoms persist, they might consider further testing to assess the function of your rectum and anal sphincter, which could help identify any underlying issues contributing to your constipation.

It's also important to note that while traditional medications for constipation (like stool softeners or laxatives) can be helpful, some patients find relief with alternative treatments, such as herbal remedies or probiotics, which you mentioned have been beneficial for you. However, it's crucial to ensure that any new treatments are safe and appropriate for your specific situation.

In summary, post-surgery constipation can be multifactorial, involving changes in bowel motility, dietary habits, and possibly the lingering effects of medications. It is advisable to maintain open communication with your healthcare provider to explore all potential avenues for relief and to ensure that your recovery continues to progress positively. If your symptoms do not improve or worsen, further evaluation may be warranted to rule out any complications related to your surgery.
