Changes in Stool Thickness After Hemorrhoid Surgery: Is It Normal? - Gastroenterology and Hepatology

Stool becomes thinner?


I would like to inquire about my situation.
I had hemorrhoidectomy surgery six months ago, and I have been taking two stool softeners daily since then.
Previously, my stools were of a thickness similar to that of a banana, but now they have become thin, resembling a cucumber.
There is no bleeding, and my bowel movements are very smooth; however, I experience significant bloating and pass gas more than ten times a day.
Is this normal? Could the stool softeners be affecting the thickness of my stools?

More Info


After undergoing hemorrhoid surgery, it is not uncommon for patients to experience changes in stool consistency and thickness. The use of stool softeners, which you mentioned taking daily, can significantly influence the characteristics of your bowel movements.
Stool softeners work by increasing the water content in the stool, making it easier to pass. While they are effective in preventing straining during bowel movements, they can also lead to softer, thinner stools. The fact that your stools have changed from a thicker consistency, resembling a banana, to a thinner one, similar to a cucumber, can be attributed to the effects of the stool softeners. This change is generally not a cause for concern, especially since you are not experiencing any pain, bleeding, or other alarming symptoms during bowel movements.

However, the increased gas and bloating you are experiencing, along with frequent flatulence, can be linked to dietary changes, the use of stool softeners, or even the healing process following surgery. After hemorrhoid surgery, some patients may alter their diets to include more fiber or other foods that can contribute to gas production. If you have recently increased your fiber intake or changed your diet, this could also explain the bloating and gas.

It is important to monitor your symptoms. If the changes in stool thickness persist or if you begin to experience discomfort, pain, or any other concerning symptoms, it would be advisable to consult with your healthcare provider. They can assess whether the stool softeners are still necessary or if adjustments to your diet or medication are needed.

In summary, while changes in stool thickness after hemorrhoid surgery can be normal, especially with the use of stool softeners, it is essential to remain vigilant about any new or worsening symptoms. If you have concerns about your bowel habits or the side effects of your medications, discussing these with your doctor can provide clarity and help ensure your recovery is on track.
