The gastric sleeve operation (also known as sleeve gastrectomy) involves removing a large portion of the stomach to reduce stomach volume substantially. The gastric sleeve operation has been established to be effective for weight loss, low risk, and associated with high patient satisfaction.* The gastric sleeve operation is by far the most popular weight loss operation in the United States.

Our Orange County gastric sleeve program has an established record of achieving excellent, industry-leading patient outcomes.* To learn more about gastric sleeve surgery and our Orange County gastric sleeve program, contact our office to schedule a free, no-obligation educational consultation with Dr. Oliak in Brea or Irvine.

About Gastric Sleeve Surgery

Gastric sleeve surgery involves removing a large 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 1.5-2 hours to complete. Patients generally stay in the hospital for 1-2 days, and return to work in 1-3 weeks. Recovery is usually rapid because of the minimally invasive, laparoscopic approach.

Patients remain on a liquid diet for 2-3 weeks after surgery, 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.

About Gastric Sleeve Outcomes

The gastric sleeve operation has been proven to be safe and effective. The better studies show that average weight loss after sleeve gastrectomy is very good (similar to gastric bypass), and complication rates are low (1/2 that of gastric bypass).*
More about gastric sleeve outcomes

The published gastric sleeve literature, however, clearly shows that different surgeons and programs have different patient outcomes statistics, for both weight loss results and complication rates. Why? Because different surgeons and programs do the gastric sleeve operation and patient care (education/follow-up/support) differently, and these differences affect patient outcomes.

Different surgeons do the gastric sleeve operation differently because there is not consensus in the weight loss surgery field on how the gastric sleeve operation should be done. There is not agreement on details like what size the sleeve should be (2 ounces?, 4 ounces?, 6 ounces?), or what dimensions/shape the sleeve should be, or where/how exactly the staple line should be placed. Because of this lack of consensus, different surgeons construct their gastric sleeves differently, and these differences affect patient outcomes.

Different surgeons/programs do patient education/follow-up/support differently, and these differences also affect patient outcomes. Surgery is a tool to help patients to lose weight, and not a cure for obesity. To achieve good long-term success, patients must establish appropriate eating/exercise habits after surgery, and patient education/follow-up/support helps to ensure that these changes happen.

Our Orange County Gastric Sleeve Program

Outcomes matter – studies clearly show that patient outcomes vary between different surgeons/programs. For example, one large 2017 study (abstract) showed that the rate for serious complications after weight loss surgery varied 17-fold (0.6%-10.3%) across 165 different bariatric surgery centers of excellence programs nationwide! Why? Because there are different surgeons at the different centers who do the operations differently.

Dr. Oliak has always prioritized achieving the best possible outcomes for his patients. By always prioritizing excellent surgery (watch gastric sleeve operation) and high-quality patient education/follow-up/support (our program), Dr. Oliak has established a long record of gastric sleeve patient outcomes – weight loss results, complication rates – that rank among the best in the weight loss surgery field (our outcomes).*

How Does Sleeve Gastrectomy Work?

Sleeve gastrectomy causes weight loss by restricting food intake and by changing the body weight ”set-point” to a lower weight.

Everybody’s body has a “set-point” weight. This is the weight that the body tries to maintain. When a person loses weight to below the set-point, the body responds by increasing hunger, appetite, and cravings, and by decreasing metabolism in an effort to cause weight regain back up to the set-point weight.

Studies have shown that for every 1kg of weight a person loses, appetite increases by about 100 calories per day, and metabolism decreases by about 40 calories per day. These changes persist (for years even) until weight regain occurs back up to the set-point weight. This biology is what makes losing weight so difficult, and what makes maintaining long-term weight loss virtually impossible.
Body weight set-point blocks weight loss

Unfortunately, these body weight control mechanisms often don’t work with weight gain to above the set-point. Weight gain, instead of leading to less appetite and a higher metabolism, often leads instead to a resetting of the set-point to the higher weight!

Weight loss surgery, we are learning, changes this biology. Weight loss surgery, in effect, resets the body weight set-point to a lower weight. To date, weight loss surgery is the only thing we know of that does this. This is the key reason for why weight loss surgery works so much better than other weight loss methods.*
Gastric sleeve changes set-point

The long-term challenge of weight loss surgery is the fact that surgery does not change the biology of weight gain. Excess calorie intake after surgery can cause weight gain and an increased set-point like it could before surgery. The key to long-term success is establishing good eating and exercise habits to prevent excess calorie intake.

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.*

Late Complications
The primary potential long-term complication after gastric sleeve surgery is heartburn/gerd. In most cases of heartburn/gerd after surgery, symptoms can be controlled with medication. The risk for heartburn/gerd can be minimized with quality surgery, but not completely eliminated.*

Gastric Sleeve Orange County – Am I a Candidate?

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

Gastric sleeve for low BMI (30-35) patients

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 requirements, such as completing a 6-month medically supervised weight loss program prior to surgery.
Payment options

Importantpatients with more severe/chronic heartburn/gerd/hiatal hernia may be better candidates for gastric bypass surgery. Heartburn/gerd is the primary potential long-term issue after gastric sleeve surgery, and the chance for this becoming a problem after surgery is higher in patients with more severe/chronic preoperative heartburn/gerd/hiatal hernia.

Gastric Sleeve Orange County – Payment Options

Payment options for gastric sleeve surgery with Dr. Oliak include PPO insurance and self-pay. Dr. Oliak does not accept HMO or MediCal insurance.

PPO insurance has become more restrictive over the past several years. When weight loss surgery is a covered benefit (often it is not), there are generally many requirements that must be met before the insurance company will preauthorize surgery. An increasingly common requirement is having to complete a 6 month medically supervised diet. Call the office for a free insurance verification to check coverage.

For patients without PPO insurance coverage for weight loss surgery, Dr. Oliak offers competitive gastric sleeve Orange County self-pay prices, and attractive gastric sleeve Orange County financing options. Approximately 50% of our patients are self-pay patients.
