Weight Loss Services at WakeMed

Obesity is a serious problem in the United States.

40% of adults are obese and another 30% are overweight[1] which means that currently, the majority of our population is either overweight or obese. 19% of children are obese1.

These numbers are increasing. Obesity is associated with numerous medical conditions such as high blood pressure, diabetes, high cholesterol, arthritis, heart disease, strokes, cancers and even death.

Safe, Effective Treatment for Obesity

Bariatric surgery is a safe, effective and lasting treatment for obesity and its associated medical conditions. WakeMed bariatric surgeons offer the vertical sleeve gastrectomy, Roux-en-Y gastric bypass and biliopancreatic diversion duodenal switch. Your surgeon and weight loss team will help guide you as to which option is best for you. All surgeries are performed minimally invasively (ie: laparoscopic, robotic). Open surgery is rarely performed.

Common Bariatric Surgeries

The sleeve gastrectomy is now the most commonly performed bariatric procedure, followed by gastric bypass and duodenal switch.

Adjustable gastric banding, at one time the most popular bariatric surgery, has not been shown to have long term effectiveness and is no longer offered although we still perform adjustments for patients who have existing bands. With sleeve gastrectomy, there is about a 60% excess weight loss compared to 70% with gastric bypass and 80% with duodenal switch3.

Gastric bypass and duodenal switch are technically more complicated relative to the sleeve gastrectomy and patients can have a higher rate of issues with malnutrition and vitamin abnormalities.

In general, bariatric surgery is quite safe with low rates of complications. Typically, patients stay 1-2 nights in the hospital. Following surgery, there is a period of diet restrictions involving a liquid diet initially with slow advance back to solid food. Weight loss occurs over a 1-2 year period following surgery.

Non-Surgical Weight Loss Procedures

There are nonsurgical weight loss procedures although the long-term safety and effectiveness are still unclear. These procedures are performed endoscopically (through the mouth with no incisions) and typically reserved for patients who cannot tolerate surgery.

Options include balloons placed in the stomach to fill up space within in the stomach, aspiration therapy which involves placing a device within the stomach that allows release of stomach contents after eating and an endoscopically performed sleeve gastrectomy. Currently at WakeMed, endoscopic sleeve gastrectomy is the only offered endoscopic bariatric procedure.
