Weight loss surgery is by far the most effective method for long-term weight loss, but it is important to understand how much weight loss surgery outcomes (weight loss results, complication rates) vary between individual surgeons and programs.*
A recent study (Ibrahim et al, JAMA Surg 2017) found that the rate of serious complications after weight loss surgery varied 17-fold (yes, 17-fold), from 0.6% to 10.3%, across 165 accredited bariatric surgery center of excellence programs nationwide.
Similarly, studies published by different surgeons report widely different average weight loss results after both gastric sleeve and gastric bypass surgery, ranging from excellent to poor.*
Why the wide disparity in outcomes between different surgeons and programs? Because different surgeons/programs do the operations in different ways, and do patient care in different ways.
The problem is that there is not industry consensus on what constitutes the best way to do surgery (gastric sleeve and gastric bypass) and patient care. Similar to plastic surgery, a lot of the details of surgery and patient care depend on the individual surgeon. What the above studies show is that these details have a big impact on patient outcomes.*
Outcomes vary between surgeons
The key differentiator between different surgeons and programs is the surgeon’s/program’s record of actual patient outcomes.*
Dr. Oliak’s #1 goal since starting his practice has been to achieve the best outcomes possible for his patients. By always prioritizing excellent surgery and patient care, Dr. Oliak has established a long record (>2500 operations since 2002) of weight loss surgery outcomes – weight loss results, complication statistics – that rank among the best in the weight loss surgery field.*
About our program
For serious complications within one month of weight loss surgery, using the same methodology as in the JAMA study quoted above, Dr. Oliak’s rate is 0.6%. This statistic ranks among the best of the 165 accredited bariatric surgery centers of excellence evaluated in the JAMA study.*

The most feared complication after gastric sleeve surgery is leak. Dr. Oliak’s gastric sleeve leak rate is 0%. Published studies report the industry average leak rate to be 2.4%, and individual surgeons report leak rates to be as high as 9%.**

Dr. Oliak’s gastric sleeve patients average 75-80% EWL (excess weight loss) at 1-3 years after surgery. Published studies report the industry average gastric sleeve weight loss to be 55-65% EWL.*

Dr. Oliak’s gastric bypass patients average 66% EWL (excess weight loss) at 10-13 years after surgery. The few good long-term gastric bypass weight loss studies report gastric bypass weight loss to average 55-60% EWL at 10+ years after surgery.*
More about gastric bypass outcomes
* Patient results vary after weight loss surgery. The weight loss outcomes quoted on this page are averages – individual patients can lose more or less weight than the average.
** Leaks can occur after gastric sleeve surgery. Past leak rates may not be indicative of future leak rates. Dr. Oliak’s 0% leak rate statistic applies to primary (non-revision) sleeve gastrectomy, primary (non-revision) laparoscopic gastric bypass, LAP-BAND® conversion to sleeve gastrectomy, and LAP-BAND® conversion to gastric bypass.
