Background: This study examines the effect of weight loss following laparoscopic Roux-en-Y gastric bypass (RYGBP) for morbid obesity on prescription drug costs in patients over the age of 54.
Methods: 78 patients aged 55 to 75 who met the inclusion criteria were identified in a database of 1,060 morbidly obese patients undergoing LRYGBP between March 2001 and March 2003. All prescription drugs and dosages were recorded preoperatively and postoperatively at 6 months, 1 year, and yearly thereafter.
