Bariatric Surgery and Constipation

Constipation after bariatric surgery can be common. Irregularity can be caused by many factors.

• Decreased fluid and fiber intake
• Reduced physical activity
• Narcotic painkillers
• Iron or calcium supplements

Many people report only having a bowel movement every two or three days following weight loss surgery. This can lead to constipation. It is important to keep track of your bowel habits and try to have a bowel movement every day.

Relief for constipation after bariatric surgery

If it has been more than 3 days since your last bowel movement, you can take milk of magnesia or Dulcolax® tablets. Follow manufacturer directions on box. If you do not have results within 24 hours, you should call your bariatric nursing team to discuss.

Also, try these tips to avoid constipation after bariatric surgery:

• Stay hydrated: Drink adequate fluids to help soften your stool. You should drink at least 48 ounces per day.
• Exercise: Take frequent short walks throughout the day, as tolerated.
• Consume adequate fiber: Because your eating is primarily focused on high-protein foods following bariatric surgery, your consumption of high-fiber food is limited. Take fiber supplements as needed to help you get at least 15 grams of fiber per day. Learn more about how to get more fiber in your diet here.
• Use laxatives when necessary. Stick with Metamucil® and other bulk-forming laxatives based on whole psyllium. Make sure to follow the mixing instructions for optimal results.
