Weight Loss Surgery Options

Weight surgery is not a quick fix, but it can be part of a comprehensive plan to help you find weight loss success, relieve problems caused or worsened by obesity and jumpstart a healthier, more active lifestyle.*

At Chestnut Hill Hospital, you can begin that journey with confidence. Board-certified and fellowship-trained surgeon, JOHN MEILAHN, M.D., specializes in laparoscopic techniques, which typically require just a few small incisions. Compared to traditional, more invasive open surgery, these procedures often offer a host of benefits, including:

  • Less pain
  • Less scarring
  • Less risk of infection
  • Fewer complications
  • Shorter hospital stay
  • Faster recovery


Roux-en-Y gastric bypass surgery is considered by the American Society for Metabolic and Bariatric Surgery (ASMBS) and the National Institutes for Health as leading surgical tool for significant lasting weight loss. It works by making the stomach smaller, allowing for smaller meals. It also causes food to bypass part of the stomach and small intestine, causing less absorption of calories and important changes in hormones that help to promote fullness.

Also called gastric sleeve, this procedure removes approximately 80% of the stomach, leaving a small tubular pouch. People are full with much smaller meals. It also changes the hormones in the stomach, helping to reduce hunger.


Duodenal Switch is an operation reserved for the severely obese patients. It is a combination of sleeve gastrectomy and an intestinal bypass. It produces more weight loss than a sleeve gastrectomy or a gastric bypass.
