Preparing for Bariatric Surgery

Fat woman obesity concept

For the estimated 93 million Americans struggling with obesity and extreme obesity, conventional methods of weight loss are often inadequate for addressing their immediate health risks.  Newer technology and minimally-invasive surgical techniques continue to reduce the risks of bariatric procedures, providing individuals with extreme weight problems and/or metabolic conditions with more treatment options.  Our medical team here at the West Hills Hospital Center for Bariatric Surgery is here to ensure that our patients have access to the resources to make sound medical decisions, which is why we’ve provided this general guide to preparing for bariatric surgery:

Initial Consultation

Bariatric surgery is generally reserved for individuals with a BMI greater than 40.0 (approximately 100 lbs. or more overweight), or a BMI greater than 30.0 with at least one obesity-related illness such as diabetes, sleep apnea, or hypertension.  The screening process includes a comprehensive physical and mental exam to ensure that prospective patients are adequately healthy to undergo a bariatric procedure.  A doctor will then perform an in-depth consultation covering the different types of weight-loss surgeries and their respective risks.


It is essential to inform your doctor of any medications and dietary supplements you are taking prior to surgery.  Even over-the-counter medications can affect surgery; for instance, regular aspirin can thin the blood and cause excessive bleeding during the procedure.  Additionally, a doctor may also prescribe certain medications prior to surgery in order to minimize the risk of complications.

Pre-Operative Diet

Depending on the type of bariatric procedure and your medical history, your healthcare provider will create a specialized pre-operative diet in order to prepare your gastrointestinal system for surgery.  Generally, this diet will consist primarily of clear liquids and possibly liquid protein supplements.  Because bariatric procedures permanently alter your digestive system, you may also be required to adhere to a strict post-operative diet as well.
