Expected Outcome of Bariatric Surgery
From the Medical Literature:
Everyone loses weight in the first weeks and months following surgery. This initial weight loss is rapid and dramatic. During this time the stomach pouch created gradually increases in size to a capacity of about 5-6 ounces. Maintaining lost weight is largely dependent on adopting proper dietary habits to ensure usefulness of the stomach pouch.
Bariatric surgical patients can expect to lose up to 65- 75% of excess weight by one year and additional weight loss in the second year. Usually weight loss stabilizes at this point, on the basis of three healthy and moderate meals a day, and avoidance of calorie-containing beverages.
Weight loss usually reaches a maximum between 18 and 24 months, postoperatively. Data suggest that mean weight loss at 5 years ranged from 48 to 74% after gastric bypass, and long-term weight loss (14 years) exceeded 50% (Pories WJ. Ann Surg 1995; 222;339). Weight loss surgery has been reported to improve several co-morbid conditions such as glucose intolerance and diabetes, sleep apnea, and obesity-associated hypoventilation (Charuzi I. Am J Clin Nutr 1992; 55(2Suppl):594S; Sugarman HJ. Am J Clin Nutr 1992; 55(2Suppl): 597S).
Our Outcomes Data:
Weight loss
- 100% of our patients lose weight
- Average weight loss at 6 months is approximately 90 lbs.; at 1 year weight loss is approximately 117 lbs.
- At 6 months, average reduction in BMI is 13.5 points (13.65), representing a 67% reduction in excess body weight
- At 1 year, average reduction in BMI is 18 points (18.11), representing a 71% reduction in excess body weight
Co-morbidities
- Almost 80% of patients have 4 or more co-morbidities prior to surgery; within 6 months nearly all these co-morbidities have improved or even resolved
- 94% of diabetes resolves within 1 month
- 66% of hypertension resolves within 6 months
- 64% of sleep apnea resolves at 1 year
Surgery
- 98% of our bariatric surgeries are successfully completed laparoscopically
- complications such as leaks (<1%) are low (overall rate <4%) which is consistent with the reported medical literature
