The Weight Loss Surgery Institute, located in Orange County, CA, offers patients a variety of options for weight loss surgery. The healthcare team is qualified to perform the following procedures: laparoscopic sleeve gastrectomy (also called sleeve surgery), laparascopic gastric bypass and Orbera® non-surgical intragastric balloon. Patients may also be candidates for treatment with the gastric band system or procedures done via endosurgial or endobariatric methods.

During an initial consultation, the weight loss surgeon will ask questions about the patient’s weight loss goals, medical history, and diet and exercise habits. The surgeon will educate the patient about the benefits, risks and potential results of each weight loss surgery option and help guide the patient’s decision-making process. Each patient will receive personalized care and treatment recommendations.

Many patients have trusted the surgeons and health care team at the Weight Loss Surgery Institute and enjoyed extraordinary weight loss results. Schedule a free consultation to learn more about your weight loss surgery options.
