The laparoscopic Roux-en-Y gastric bypass leads to weight loss through two mechanisms: restriction and malabsorption.
Expected weight loss from Roux-en-Y gastric bypass surgery
Patients generally lose between 65% to 80%* of their excess weight. The exact amount of weight lost depends on your pre-operative body mass index (heavier people lose more weight), compliance with dietary instruction, and increasing your activity levels (exercise). Commitment to proper food choices, nutritional supplementation, and increased activity is essential to maximizing and maintaining your weight loss in the long term. Failure to make these commitments can lead to weight regain.
Minimally invasive gastric bypass surgery
Dr. Josh Roller, Dr. Yong Kwon, Dr. Jaime Dutton, and Dr. Jessica Pries typically perform this procedure laparoscopically 99% of the time, aiming to avoid creating a large incision in the abdomen. It’s extremely rare for our surgeons to have to perform open weight loss surgery. Most of our patients stay for one night in the hospital and are able to go back to work in a week’s time — with less than a 1% wound complication rate.
