The laparoscopic Roux-en-Y Gastric Bypass leads to weight loss through 2 mechanisms, restriction and malabsorption. First, the Gastric bypass produces restriction by reducing the size of the stomach, reducing the amount of food you can eat before you feel full. Also, by bypassing a portion of the small intestine, the amount of food the body will absorb is reduced, thus producing malabsorption. Note, malabsorption just means not absorbing all of the calories one eats. Malnutrition, on the other hand, is produced by bypassing too much of the small intestine, as with the Traditional Duodenal Switch.  This operation is considered the gold standard for weight loss surgery, as it has been in existence the longest, and has been extensively used since 1967.

A small stomach pouch (about the size of a medium egg) is created with a stapler device. The small intestines are then divided and one end brought up and connected to the small stomach pouch using the stapler. The intestines are reconnected further downstream. Dr. Josh Roller, Dr.

Yong Kwon, Dr. Josh Mourot, and Dr. Jaime Dutton typically perform this procedure laparoscopically over 99% of the time avoiding a large incision in the abdomen; It is extremely rare for our surgeons to have to perform open weight loss surgery. Most of our patients stay just one night in the hospital, are able to go back to work in a week’s time, and have less than a 1% wound complication rate.

Expected Weight Loss

65-80% of your excess weight*

Patients generally lose between 65-80 of their excess weight*. The exact amount of weight lost depends on your preoperative 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.
