Diarrhoea, loose stools after gastric sleeve surgery

Posted on 10 May, 2015

After gastric sleeve surgery, many patients will notice a change in bowel habit. This is not a cause for concern and alarm.

Some patients become constipated and others notice loose stools. The reasons for change in bowel habits after gastric sleeve surgery are many:

1. Change in diet: Optifast before weight loss surgery and fluid diet afterwards

2. Anesthetic and surgery: this affects bowel performance

Generally, most people will return to their pre-existing bowel function within six weeks after surgery. This correlates with return to a normal diet and lifestyle.

If diarrhoea or loose stools persist, then we recommend some Gastrostop. Bulking agents such as Metamucil may be helpful.

If constipation persists, try extra fluid, high fiber and exercise.

As always please feel free to contact the dietitian at our clinic on (02) 4323 7000 for further clarification.

Weight loss surgery is a time of change and the bowels do change but time should fix this.
