About Gastric Sleeve

Gastric sleeve surgery (also known as sleeve gastrectomy), 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. Patients typically 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 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.

Gastric Sleeve Weight Loss

Sleeve gastrectomy typically results in excellent weight loss – the better surgeons/programs report an average of 60-80% excess weight loss (EWL) at 1-3 years after surgery.* Long-term studies (5+ years) show that patients, on average, maintain the majority of their initial weight loss over time.*
More about gastric sleeve weight loss

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.*

Resetting the body weight set-point to a lower weight is the key to why the gastric sleeve operation works as well as it does. This is what makes long-term maintenance of weight loss possible after surgery. Because nonsurgical weight loss methods don’t change the body weight set-point, long-term maintenance of weight loss after diet and exercise programs is virtually impossible.*

Why Choose Gastric Sleeve?

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 (discussed above), high patient satisfaction, and proven safety.*

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

Proven Safety
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 preservation of more normal anatomy results in less long-term risk.*

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.

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

Good gastric sleeve Orange County candidates 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.
Achieving gastric sleeve success

Importantpatients with more severe/chronic heartburn/gerd/hiatal hernia are often 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 elevated in patients with more severe/chronic preoperative heartburn/gerd/hiatal hernia.

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. The risk for heartburn/gerd can be minimized with quality surgery, but not completely eliminated.*
