Weight loss surgery is the most effective way to lose weight and keep weight off. Weight loss surgery can improve or resolve obesity-related conditions such as diabetes, high blood pressure, acid reflux and sleep apnea. It also decreases obesity-related cancer risk by 30%. Weight loss surgery can help improve your overall quality of life.

The Cedars-Sinai Weight Loss Center is a comprehensive center with expert multidisciplinary providers and world-class care. We are proud to be ranked among the top hospitals for gastrointestinal surgery in the nation.

We are also a Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) accredited bariatric center, with a high volume of weight loss surgeries every year.

Our surgeons offer Roux-en-Y gastric bypass, sleeve gastrectomy and the laparoscopic adjustable gastric band. We also offer revision surgery for patients who have had weight loss surgery before and have not achieved desired results.

To qualify for weight loss surgery, you must have either a:

  • BMI of 40 or greater
  • BMI of 35-40 with obesity-related conditions such as diabetes, high blood pressure, sleep apnea or gastroesophageal reflux disease (GERD)

Body mass index (BMI) is a tool to screen for obesity, factoring in your height and weight. Learn your BMI with our BMI calculator.

On average, most patients stay in the hospital one to two days after surgery. Most return to work two to three weeks after surgery.

Maximum weight loss typically occurs 12-24 months after surgery. Individual weight loss varies depending on:

  • Age
  • Weight before surgery
  • Level of physical activity
  • Diet
  • Type of surgery

You will need to follow a bariatric diet and exercise daily, take bariatric vitamins lifelong, refrain from using nicotine (including cigarettes) and minimize alcohol use.
