Liposuction vs Bariatric Surgery: Which is Good for Weight Loss in the Long Term?

Liposuction or Bariatric Surgery may be an ideal solution to those who’re extremely obese and not able to lose weight after trying out different methods such as diet & exercise plans.

If you’re planning to go under the knife to reduce excess weight, then first check your BMI (body mass index).

Below are typical categories for your BMI number.

<16.0Extremely underweight
16.0 to 16.9Severely underweight
17.0 to 18.4Underweight
18.5 to 24.9Normal weight
25.0 to 29.9Overweight
30.0 to 34.9Obesity (Class 1)
35.0 to 39.9Obesity (Class 2)
>= 40Morbid Obesity

So, going by this table, only those with excess body fat usually opt for these weight reduction surgeries.

But, there is a little catch here. It is only suggested to go under the knife only if you fall under the Obesity (class 2) and Morbid obesity categories.

The Overweight and Obesity (class 1) individuals can easily lose those few extra kilos by following a healthy low carb high protein diet and some easy weight loss exercises.

Difference b/w Liposuction and Bariatric Surgery

Liposuction is a cosmetic surgery where the excess fat is removed through a small incision made near the affected areas.

The process involves injecting large amounts of fluid into the layers between the fat and muscle. The device will then breaks up fat cells, which are then suctioned out of the body.

The surgery usually lasts for 2 to 4 hours depending on the amount of fat to be drawn out and the location to be treated.

Unfortunately, it does not address the actual issues that are causing the person to gain weight and so the person who’d undergone the liposuction procedure may gain all the lost weight in the future.

Bariatric Surgery vs Liposuction for Weight Loss

Whereas, Bariatric surgery is for those who’re extremely obese. It includes 3 different procedures – Gastric Sleeve, Gastric Bypass and LAP-BAND® surgery.

None of these procedures remove the fat, but address the cause of excess fat and helps in achieving long-term weight loss results.

So, if you’re looking for long-lasting results, then it is highly advised to opt for any of the three types of Bariatric surgeries.

What Type of Bariatric Surgery is Best for Me?

In order to figure out the best bariatric surgery for you, first we need to know the basics, pros and cons of each of these types in detail.

1. LAP-BAND® Surgery

The main motto of this surgery is to significantly reduce the quantity of food you’re eating.

Lap Band Surgery for Weight Loss

It is achieved by reducing the capacity of your stomach by using the LAP-BAND®/REALIZE™ Band.


  • Feel full quickly
  • Mortality rate is lower
  • Least invasive surgical approach
  • Stomach stapling or cutting is not required. So, no scars.
  • No intestinal rerouting required like other two techniques
  • Adjustable without surgery
  • Low malnutrition risk
  • Laparoscopic surgery; hence the recovery is very fast


  • Band problems
  • Blood clots
  • Changes in bowel functions
  • Gallstones
  • Indigestion
  • Nausea/Food intolerance
  • Pneumonia
  • Pouch dilation

2. Gastric Bypass Surgery

In this procedure, the stomach is shrinked to a smaller size by creating a pouch at the top of the stomach.

Gastric Bypass Surgery Procedure

This smaller stomach is directly connected to the small intestine’s middle portion, thus the link between the upper portion of the small intestine and the other part of the stomach is disabled.

This allows the food to bypass part of the small intestine and helps in losing weight naturally.


  • Very quick weight loss results compared to gastric sleeve
  • Mixed procedure (restrictive and malabsorptive)
  • Controls diabetes
  • 4 decades of successful history


  • Bowel obstruction
  • Gastric pouch enlargement
  • Malnutrition
  • Anemia
  • Chronic diarrhea
  • Anastomotic ulcers
  • Smelly stools
  • Needs regular checkups & lab tests

3. Gastric Sleeve

There is a hormone called ‘grehlin’ in our body that is responsible for the feeling of hunger.

Gastric Sleeve Surgery for Weight Loss

Gastric sleeve or sleeve gastrectomy is a procedure that involves resectioning of the particular portion of your stomach that produces this hunger hormone.

So, the patients who opt for Gastric sleeve procedure usually see a reduction in their appetite, thereby weight loss happens naturally.


  • Decent weight loss results (not quick/not slow)
  • Reduced high blood pressure issues
  • Reduction in high cholesterol
  • Eliminated or reduced type 2 diabetes
  • Improved fertility
  • Reduced or eliminated migraines and sleep apnea


  • Leaking
  • Blood clots
  • Aversion to food
  • Nausea and Vomiting
  • Gastroparesis – delay in food leaving the stomach
  • Malnutrition
  • Loose skin

Therefore, based on your condition and lifestyle, the doctor will suggest you the best type of bariatric surgery among the three.
