Why Gastric Sleeve Surgery?

The gastric sleeve operation has become the most popular operation for weight loss worldwide over the past 10 years because of several compelling strengths:

Effective Weight Loss
Weight loss after sleeve gastrectomy, according to the published studies from the better surgeons, averages 60-80% EWL (excess weight loss). Weight loss is typically fast and dramatic, occurring over about one year. Long-term (5-10 years), studies show that patients tend to maintain the majority of their initial weight loss.*

These statistics are from published studies from the better surgeons/programs. Not all surgeons/programs report equally good weight loss results – some surgeons/programs do a better job and achieve better patient outcomes than others. To maximize the chances for a great weight loss outcome, choice of surgeon/program is important.*

High Patient Satisfaction
A big reason for why patients like the gastric sleeve operation so much is because typically the experience of eating is similar to the normal experience of eating, except, of course, for the fact that the stomach is much smaller.*
Patient testimonials

Low Risk
GI tract (stomach, intestines) anatomy is preserved in a more normal form with sleeve gastrectomy. There is no intestinal rerouting like with gastric bypass, and no implanted foreign body like with gastric banding. This more normal anatomy results in less risk for long-term issues.*

About Gastric Sleeve Surgery

Gastric sleeve surgery involves surgically removing a portion of the stomach to reduce stomach volume by 80-90%. Stomach volume is typically reduced from about 30 ounces to approximately 3-4 ounces. The exact size can be adjusted up or down depending on patients’ specific circumstances. Over time, the small sleeve stomach will expand to approximately 6-8 ounces.

The gastric sleeve operation is done laparoscopically, generally using 5 small incisions. The operation typically takes 1-2 hours. Patients typically stay in the hospital for 1-2 days, and return to work in 1-3 weeks. Recovery is usually quick because of the minimally invasive, laparoscopic approach.

After surgery, Dr. Oliak’s patients remain on a liquid diet for 3 weeks, and then slowly transition onto solid foods. Meal portion sizes are typically 2-4 ounces when patients start solid food, and slowly increase in size to approximately 6-8 ounces over the first 1 year.

Weight loss is typically fast and dramatic. Dr. Oliak’s gastric sleeve weight loss statistics are as follows: average 20% EWL (excess weight loss) at 1 month, average 61% EWL at 6 months, and average 76% EWL at 1 year.

How Sleeve Gastrectomy Works

Sleeve gastrectomy causes weight loss by restricting food intake and by altering the biology of weight regulation by resetting the body weight “set-point” to a lower weight.*

Restriction of food intake of course occurs because of the small sleeve stomach. The stomach expands over time, so the stomach is made to be very small initially. Because of this, restriction is most pronounced early after surgery, and slowly lessens over time. Stomach volume roughly doubles over time.

In addition to restriction, gastric sleeve surgery also changes the biology of weight regulation. The body has a “set-point” weight that the body works hard to maintain. This is why nonsurgical weight loss is so difficult. When weight loss occurs to below the set-point weight, hunger/appetite increases, cravings increase, and metabolism decreases. These changes very effectively cause weight regain back up to the set-point weight.
Why nonsurgical weight loss is so hard

The set-point is like a body weight thermostat that can reset higher, but not lower. When a person gains weight, the set-point unfortunately often will reset to the new higher weight.

Weight loss surgery changes the bodyweight set-point to a lower weight. Nothing else that we know of does this, other than surgery. With a lower set-point, the body accepts a lower weight as acceptable, without trying to achieve weight regain.*
Surgery lowers “set-point”

This changed weight regulation biology gives patients the ability to not just lose weight, but to maintain weight loss over time. This is the key reason for why weight loss surgery works so much more effectively than nonsurgical methods for weight loss, and a compelling justification for choosing to undergo weight loss surgery.*

Gastric Sleeve Orange County – Am I a Candidate?

Gastric sleeve Orange County candidates generally must be at least 50-100 pounds overweight (BMI 30 or greater), and have tried and failed to lose weight and keep it off.

More about sleeve for BMI 30-35

Insurance companies are more restrictive – candidates generally must have either a BMI of >40, or a BMI of 35-40 with other medical problems such as diabetes, high blood pressure, or sleep apnea. Insurance companies often also have other onerous requirements, such as the completion of a 6-month medically supervised weight loss program prior to surgery.
Payment options

Good gastric sleeve Orange County candidates also understand that surgery is a tool to help with weight loss, not a cure for obesity. Good candidates understand the necessary changes they need to make in their eating/exercise habits after surgery, and are willing/capable of making these changes.

Sleeve Gastrectomy 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.*
More about gastric sleeve outcomes

Late Complications
A major strength of sleeve gastrectomy over gastric bypass and LAP-BAND®, as explained above, is the lower risk for long-term complications. The primary potential long-term complication after gastric sleeve surgery is heartburn/gerd. The risk for heartburn/gerd can be minimized with quality surgery (choice of surgeon important), but not completely eliminated.*
