Types of Bariatric Procedures

Our surgeons are specialized in minimally invasive techniques (laparoscopic surgery) so that you can recover more quickly and with less pain and less risk for complications. On average, patients that undergo laparoscopic surgery are hospitalized for 1-2 days and can return to work 2-4 weeks after surgery.

Michigan Medicine performs two types of bariatric surgery procedures: gastric bypass and sleeve gastrectomy.

Gastric Bypass

Gastric bypass surgery involves dividing the stomach to create a gastric pouch (roughly the size of an egg) and surgically connecting the small intestine to the pouch. This causes food to bypass the stomach and first portion of the small intestine. The operation is typically 2-3 hours long.

Sleeve Gastrectomy

Sleeve gastrectomy surgery involves the surgical division and removal of approximately 80-85% of the stomach. The operation is typically 1-2 hours long.

Recovery and Follow-Up

The gastric bypass and sleeve gastrectomy procedures follow the same recovery plan, diet progression, and restrictions:

  • 1-2 days of hospitalization at University Hospital
  • Two-week follow-up appointment at the Michigan Medicine Bariatric Surgery Clinic
  • Two-month follow-up appointment at the Michigan Medicine Bariatric Surgery Clinic
  • Six-month and yearly follow-up visits in the MEND clinic

Upon discharge, patients need to tolerate a liquid diet, stay hydrated (taking in 64 fluid ounces daily) and walk 30-45 minutes daily.

Restrictions (2-4 weeks):

  • No heavy lifting (over 10-20 lbs.)
  • No driving while taking narcotic pain medication
  • No baths or pools (showering is fine) until incisions are fully healed

Endoscopic Bariatric Therapy (EBT)

Michigan Medicine also offers non-surgical endoscopic bariatric therapy (EBT) for weight loss. Our team and tools can help determine the best procedure for each individual patient.
