What is Bariatric Surgery and How Many Types Are There?

An illustrated diagram shows the sleeve gastrectomy bariatric surgery on a stomach before and after surgery.Before going into different types of bariatric surgery with you, Dr. Benavente will explain the basics of the procedure as well as some of the requirements needed to qualify. Essentially, bariatric surgery helps people lose weight by restricting the amount of food the stomach can hold.

To be a candidate for a bariatric procedure, your BMI needs to be less than or equal to 40 and you must be a minimum of 100 pounds overweight— or, you have to have a medical condition such as type II diabetes, hypertension, osteoarthritis, gastrointestinal disease, heart disease, or sleep apnea.

Once Dr. Benavente has determined you are eligible for surgery, he will discuss which of the following surgery weight-loss approaches is best for you:

  1. Adjustable Gastric Band

Also referred to as “the band,” this type of surgery utilizes an inflatable band around the upper stomach to produce a small stomach pouch. Considered the least invasive weight loss surgery method the outcome of the procedure results in reduced recovery time, and fewer potential complications. This procedure promotes 40% to 50% weight loss, is reversible, and carries the least amount of risk for vitamin deficiencies.

  1. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

For this surgical approach, the first portion of the small intestine is divided near the outlet of the stomach. The bariatric surgeon then takes the second (latter) part of the small intestine and connects it to the outlet of the stomach. Following surgery, patients can lose 60% to 70% of excess weight and can often eat “normal” meals (in time). It also reduces appetite and is the most effective procedure in preventing diabetes as compared to other bariatric surgeries.

  1. Gastric Bypass

For gastric banding surgery, the bariatric surgeon creates a small stomach pouch at the top of the stomach and then divides the small intestine and strategically reattaches it. When complete, the procedure limits the amount of food you can eat, encourages 60% to 80% weight loss, and may even increase your energy.

  1. Sleeve Gastrectomy

Performed laparoscopically, a sleeve gastrectomy removes an estimated 80% of the stomach, with the leftover portion of the stomach resembling a banana. The outcome of the procedure typically only requires two inpatient days of recovery, averages 50% weight loss, and reduces appetite.
