Weight loss surgery transforms lives by enabling long-term weight loss, and by improving health and wellbeing.* If you have at least 50-75 pounds to lose, weight loss surgery might be the ideal solution!

Read below about the most popular weight loss surgery, gastric sleeve surgery, and about how Dr. Oliak does gastric sleeve surgery and patient care to achieve excellent, industry-leading patient outcomes.*

About Gastric Sleeve Surgery

Gastric sleeve surgery (also known as sleeve gastrectomy, vertical sleeve gastrectomy, VSG) involves surgically removing a large portion of the stomach, to reduce stomach volume from approximately 30-40 ounces to approximately 3-4 ounces. Over time, the gastric sleeve will expand to approximately 6-8 ounces.

The gastric sleeve operation is done laparoscopically or robotically, using small incisions. The operation typically takes 1-2 hours. Patients generally stay in the hospital for 1 day, and return to work in 1-2 weeks.

Why Gastric Sleeve Surgery?

Reasons to consider sleeve gastrectomy include the following:

  • Highly effective for weight loss – similar to gastric bypass
  • Established – proven safe/effective over >15 years
  • Minimally invasive – laparoscopic or robotic approach
  • Low risk – less risk than gastric bypass
  • High patient satisfaction – patients love it!

Patients and surgeons commonly choose gastric sleeve surgery over alternative weight loss surgeries. Currently, 70-75% of all first time weight loss surgeries in the United States are gastric sleeve operations.

Patient Testimonials

Gastric Sleeve Weight Loss

Weight loss after gastric sleeve surgery is generally fast and dramatic, and occurs over 1-1.5 years.

Gastric sleeve patients lose, according to the better published studies, an average of 60-80% of their excess weight after surgery, and maintain, on average, most of their initial weight loss long-term.*

Gastric Sleeve Weight Loss

How Does Sleeve Gastrectomy Work?

Sleeve gastrectomy surgery causes weight loss by restricting food intake, and by changing the biology of weight regulation.

Weight loss without surgery (diet and exercise programs) is hard to achieve, and virtually impossible to maintain, because of biologic mechanisms that work to maintain bodyweight and prevent weight loss.

Sleeve gastrectomy surgery changes this biology. In effect, surgery resets the bodyweight “set-point” to a lower weight.

This biology change is what makes long-term weight loss possible after surgery, and what makes gastric sleeve surgery (and gastric bypass surgery) so compelling!*

Surgery Changes Set-Point

Why Choose Our Orange County Program?

Gastric sleeve surgeons and programs are not all the same. Different surgeons and programs have different ways of doing surgery (e.g. sleeve size, dimensions) and patient care (education, follow-up, support).

These differences result in differences in patient outcomes. Published studies make clear that some surgeons and programs achieve much better weight loss results and much lower complication rates than others.*

In Dr. Oliak’s view, the obvious best way to choose a surgeon and program is by actual patient outcomes – weight loss and complication statistics. Other parameters (convenience of location, online reviews, word-of-mouth, insurance, etc.) are just not reliable indicators of quality and performance.

Dr. Oliak’s #1 goal, since starting his career in 2002, has been to achieve the best outcomes possible for his patients. For the outcomes that matter most – weight loss, early major complications (e.g. leak), and late complications (e.g. acid reflux) – Dr. Oliak’s statistics beat the industry benchmarks, often by a wide margin.*

More About Gastric Sleeve Surgery

As discussed above, the vertical sleeve gastrectomy operation involves surgically removing a large portion of the stomach, to reduce stomach volume from approximately 30-40 ounces to approximately 3-4 ounces. Over time, the gastric sleeve will expand to approximately 6-8 ounces.

This of course is a very simplistic explanation of the operation. In actuality, there is not an accepted “best way” to do the gastric sleeve operation. There is not industry agreement on things like ideal sleeve size, shape, dimensions, technique, etc.

Because of this lack of standardization, different surgeons do the gastric sleeve operation in different ways. Published studies using videos of surgeons’ gastric sleeve technique show a “vast amount of variation” in technique between surgeons.

Gastric Sleeve Operations Not All The Same

Variation in surgical technique between surgeons is a big reason for why patient outcomes (weight loss results, complication statistics) vary so much between individual surgeons.

How Dr. Oliak Does Gastric Sleeve Surgery

By closely tracking the details of his gastric sleeve surgical technique, and his patient outcomes, he has learned over time the technique details that result in the best patient outcomes.

Dr. Oliak’s key technique details include the following: 1) create a small volume sleeve, but not too small, 2) avoid a too small/too narrow sleeve to avoid heartburn/gerd complications, 3) measure before cutting to achieve exact desired sleeve dimensions/size/shape, 4) be conservative with hiatal hernia diagnosis and repair to avoid long-term heartburn/gerd complications.

Sleeve Gastrectomy Surgery Recovery

Because the gastric sleeve operation is minimally invasive, recovery is generally rapid. Patients typically are discharged from the hospital the day after surgery, and return to work in 1-2 weeks.

Gastric sleeve Orange County patients remain on a liquid diet for 2-3 weeks after surgery, and then slowly transition onto solid foods.

Sleeve Gastrectomy Surgery Follow-Up

Gastric sleeve Orange County surgery is a tool that must be used appropriately to achieve good long-term success. Using the surgical tool effectively requires education, guidance, and support. A primary purpose of follow-up after surgery is to get the education, guidance, and support that will enable maximum weight loss success.

How Dr. Oliak Does Gastric Sleeve Follow-Up

Dr. Oliak prioritizes frequent follow-up early after surgery. He generally sees patients after surgery at 1wk, 2wks, 5wks, and then monthly until weight loss progress is such that goal weight will be achieved at 1 year.

Because the body adapts to the gastric sleeve over time (the sleeve gets bigger), it is important for patients to take advantage of the early months after surgery to lose as much weight as possible. Not taking full advantage of the early restriction will limit ultimate weight loss.

When patients come in for follow-up, Dr. Oliak evaluates whether weight loss progress is on track for achieving goal weight. Based on this, Dr. Oliak can discuss with patients what changes should be made, and what goal weight should be for the next visit.

Frequent follow-up early after surgery is one of the key reasons for why our gastric sleeve Orange County weight loss statistics are significantly better than the industry averages.*

Sleeve Gastrectomy Surgery Orange County – What Are the Risks?

Sleeve gastrectomy is considered a safe operation, but complications can occur, as they can for any operation.

Early Complications
The two most feared potential early complications after gastric sleeve surgery are bloods clots and leaks. The risk for blood clots and leaks can be minimized with quality surgery and good patient care, but not completely eliminated.*

Late Complications
The primary potential long-term complication after gastric sleeve surgery is heartburn/gerd. When heartburn/gerd does occur after surgery, symptoms generally can be easily controlled with medication. The risk for heartburn/gerd can be minimized with quality surgery, but not completely eliminated.*
