About Gastric Sleeve Surgery

The gastric sleeve operation (also known as sleeve gastrectomy) is the most commonly performed weight loss operation in the United States and worldwide. Why? Because sleeve gastrectomy offers the compelling combination of excellent weight loss, low risk, and high patient satisfaction.*

The gastric sleeve operation involves removing a large portion of the stomach, to reduce stomach volume from approximately 30-40 ounces to approximately 3-4 ounces. Over time, sleeve volume will increase to approximately 6-8 ounces.
Watch Dr. Oliak do a gastric sleeve operation

The gastric sleeve operation causes weight loss by restricting food intake, and by changing the biology that regulates bodyweight, resulting in a lower bodyweight “set-point.” This biology change is what makes long-term weight loss possible after surgery.* The reason nonsurgical weight loss methods don’t work long-term is because nonsurgical weight loss methods don’t change the bodyweight set-point.

Gastric Sleeve Outcomes

The sleeve gastrectomy operation has been proven to be a safe and effective operation for weight loss – the better published studies report an average of 60-80% excess weight loss at 1-3 years after surgery.* Long-term studies (5-8 years) show that patients maintain the majority of their weight loss over time.*

The published studies, however, do show significant variation in outcomes between different surgeons and programs – some surgeons and programs achieve much better weight loss results and much lower complication rates than other surgeons and programs.*
Surgeon outcomes vary

The fact is, different surgeons and programs do surgery and patient care (education, follow-up, support) in different ways, and these differences have a major affect on patient outcomes.*
Gastric sleeve operations are not all the same

Sleeve Gastrectomy Surgery and Recovery

Gastric sleeve surgery involves removing a large portion of the stomach to substantially reduce stomach volume. Stomach volume is typically reduced from about 30-40 ounces to approximately 4 ounces. The exact sleeve 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.

Sleeve Gastrectomy Changes Bodyweight “Set-Point”

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

Everybody 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. 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 (gastric sleeve surgery, gastric bypass 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.*
Weight loss surgery 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. 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.*

To read more about gastric sleeve risks and our gastric sleeve complication statistics, see our gastric sleeve risks page.

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 the completion of 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. The chance for hearburn/gerd becoming a problem after surgery is higher in patients with more severe/chronic preoperative heartburn/gerd/hiatal hernia.

* Patient outcomes vary after weight loss surgery. Individual patients can do better or worse than the average.
