Bariatric Surgery vs. Liposuction: Which Procedure Provides Maximum Weight Loss?​

Bariatric surgery also known as weight loss surgery is a quick and effective way for anyone dealing with Type 2 diabetes and obesity. It’s estimated roughly 13% of adults in the United States have diabetes, according to a 2020 report from the Centers for Disease Control and Prevention (CDC). Plus, nearly half of all people with diabetes suffer from obesity, which means they have a body mass index (BMI) over 30.In fact, there is a strong link between obesity and the risk of developing type 2 diabetes. If a person has diabetes, their doctor may recommend losing weight as part of their treatment plan.

Bariatric Surgery vs. Liposuction

Let’s take a closer look at the difference between a Sleeve Gastrectomy (gastric sleeve) and Liposuction. Anyone with a body mass index (BMI) over 30 is considered obese and would benefit greatly from either Gastric Sleeve or Gastric Bypass surgery. Liposuction on the other hand is an instant gratification procedure that’s recommended for non-obese patients who have identified problem areas of fat that diet and exercise alone won’t remove. Here’s what you’ll need to know on each procedure to make an informed decision:

Gastric Bypass

Gastric Bypass makes your stomach smaller and allows food to bypass part of the small intestine. The most common gastric bypass surgery is a Roux-en-Y Gastric Bypass. Your stomach is made smaller by creating a pouch at the top of your stomach. Your new smaller stomach is connected directly to the middle portion of your small intestine, bypassing the rest of your stomach and the upper portion of your small intestine. Both Gastric Sleeve and Gastric Bypass are ideal procedures to address the cause of excess fat, rather than simply removing fat. Bariatric surgery can achieve long-term weight loss and is the best option for patients with a BMI of 30 or over.

Gastric Sleeve

Gastric Sleeve surgery is highly recommended if you’re seriously overweight or obese. Gastric Sleeve involves resectioning the portion of your stomach that produces ghrelin, which is the hormone that is most responsible when you feel hungry. As a result, patients who undergo gastric sleeve report a reduced appetite, which translates into losing weight. Your bariatric surgeon might also discuss Gastric Bypass surgery as an alternative.

Laser Liposuction

Laser liposuction involves using lasers to emulsify and liquefy your fat before it’s removed via your lymphatic system. This technique is non-surgical and makes it easier to vacuum out your fat via liposuction. Lasers also aim to stimulate the production of your collagen and elastin, which results in firmer, tighter, and smoother skin. Not only will you remain awake the entire time, but you’ll also be able to walk right out of your procedure and enjoy instant, dramatic results. Most patients report losing three inches or more.


Liposuction is a popular surgery that provides you with instantaneous results, yet it is not recommended if you suffer from obesity. Liposuction is a non-surgical procedure that uses a suction technique to remove stubborn pockets of fat from specific areas of your body, including your abdomen, hips, thighs, buttocks, arms or neck. Liposuction also shapes or contours these areas. Other names for liposuction include lipoplasty and body contouring. You will remain awake during liposuction as your physician will likely recommend a local anesthesia. There are some instances where patients request general anesthesia yet this percentage is minor. Some may opt for laser liposuction vs. liposuction.

How Many Inches Can You Lose?

Patients often ask how many inches or pounds they can expect to lose as a result of laser liposuction, traditional liposuction or bariatric surgery. It’s advisable to schedule an initial consultation with a general surgeon specializing in either liposuction or bariatric surgery to determine how many pounds or inches you’ll likely lose. Laser liposuction uses body contouring technology so it targets the overall look and shapes your body takes on. Bariatric surgery is intended to address the cause of excess fat rather than simply removing fat.

Duodenal Switch

With a duodenal switch, you’ll lose more weight than opting for a gastric sleeve or a gastric bypass. Having a duodenal switch procedure means you can expect to lose about 85% – 100% of excess weight. For example, if you needed to lose 150 pounds or more then a duodenal switch can easily remove your excess pounds and you would be able to maintain your weight loss years later.

A biliopancreatic diversion with duodenal switch (BPD/DS) is a complex procedure that induces weight loss by a gastric sleeve. This includes a stapling instrument where a significant portion of the stomach is removed, leaving a tiny tube or sleeve from the top to the bottom of your stomach. With less in your stomach, you will feel a sense of fullness much faster and will consume less.

Next, the procedure entails rerouting food away from the upper part of your small intestine. This step affects the common pathway of food because your small intestine is separated and connected to the end of your small intestine, this limits the amount of absorption of nutrients and calories.

Lastly, your duodenal switch procedure changes the way that your bile and digestive enzymes are broken down. You’ll experience more weight loss due to the decrease in calories.

Robotic Surgery

Robotic bariatric (weight loss) surgery uses a cutting edge robot called the da Vinci Robotic System. Unlike traditional surgery, robotic surgery uses small incisions and is less invasive. Dr. Alibhai has multiple years of experience with this robotic system and is only among a handful of surgeons that have this sort of experience with the da Vinci system. Most candidates considered for robotic surgery are typically severely obese. Severely obese is defined as having a BMI (body mass index) over 40%. Other factors your surgeon considers include age, high blood pressure, diabetes, etc. If you wonder if you’re a candidate for robotic surgery you can call to schedule an appointment with Dr. Alibhai for a consultation to see if you qualify.
