Laparoscopic Gastric Bypass

Laparoscopic Gastric Bypass works via both restriction and modest malabsorption.  In this procedure, stapling creates a small (15 to 20 ml) stomach pouch.  The remainder of the stomach is not removed but is divided from the stomach pouch.  The outlet from this newly formed pouch empties directly into the lower portion of the jejunum, thus bypassing the duodenum and lower stomach.

  • As a result of the intestinal rerouting, the patient will react differently to sugar and will experience “dumping syndrome” (causing cramps, sweating, nausea, and vomiting) if they ingest more than 5 grams of sugar per serving of anything.  (This is a positive as it decreases the likelihood that the patient will ingest empty calories from sugary foods).

  • Must avoid Ibuprofen products such as Motrin, Aleve, Advil, etc. as these drugs could cause ulcers.
