5 Types of Bariatric Surgery for Weight Loss

5 Types of Bariatric Surgery for Weight Loss | Med Turkish


Bariatric surgery, also known as weight loss surgery, is a medical procedure designed to assist individuals who struggle with obesity in achieving significant and sustainable weight loss. These surgeries alter the digestive system to reduce food intake, leading to improved health and quality of life. In this article, we will explore three common types of bariatric surgery: Gastric Bypass, Gastric Sleeve, and Gastric Balloon, highlighting their key features and benefits.

Gastric Bypass Surgery (Roux-en-Y Gastric Bypass):

Gastric bypass surgery is one of the most well-established and effective bariatric procedures. During this surgery, a small pouch is created at the top of the stomach, significantly reducing its size. The small intestine is then rerouted and attached to this pouch, bypassing a portion of the stomach and the upper part of the small intestine. This results in both reduced calorie intake and reduced calorie absorption.


Significant and sustained weight loss.

Improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea.

Restriction of food intake and malabsorption of calories.

Gastric Sleeve Surgery (Sleeve Gastrectomy):

Gastric sleeve surgery involves the removal of approximately 80-85% of the stomach, leaving behind a narrow, banana-shaped tube or sleeve. The procedure restricts the amount of food a person can consume, leading to early satiety and reduced calorie intake. Unlike gastric bypass, the small intestine remains intact in this surgery.


Significant weight loss.

Improvement in obesity-related conditions.

Lower risk of nutritional deficiencies compared to some other bariatric surgeries.

Gastric Balloon (Intragastric Balloon):

The gastric balloon, a non-surgical and temporary option, involves inserting a deflated balloon into the stomach through the esophagus and then inflating it with a saline solution. This fills space in the stomach, creating a sensation of fullness, which reduces food intake. Gastric balloons are typically left in the stomach for six months and are then removed.


Non-surgical and minimally invasive.

Temporary intervention.

Can serve as a jumpstart to weight loss or for individuals who may not be suitable candidates for surgical procedures.

Laparoscopic Adjustable Gastric Banding (Lap-Band Surgery):

Lap-band surgery involves placing an adjustable silicone band with an inflatable inner collar around the upper part of the stomach, creating a small pouch. The band can be adjusted through a port placed under the skin, allowing for personalized restriction of food intake. Lap-Band surgery is reversible, making it a less permanent option compared to some other bariatric procedures.


Adjustable to suit individual needs.

Reversible procedure.

Lower risk of nutritional deficiencies.

Single Incision Laparoscopic Surgery (SILS):

Single-incision laparoscopic Surgery (SILS) is a minimally invasive approach to bariatric surgery. It combines the benefits of traditional bariatric procedures with smaller incisions and potentially less scarring. The choice of procedure within SILS, whether it’s gastric sleeve, gastric bypass, or gastric banding, depends on the patient’s specific circumstances and goals.


Minimally invasive with smaller incisions.

Reduced post-operative discomfort and quicker recovery compared to traditional open surgery.


Bariatric surgery offers a range of options for individuals looking to achieve substantial and sustainable weight loss. The choice of procedure depends on various factors, including the patient’s overall health, weight loss goals, and personal preferences. Gastric Bypass, Gastric Sleeve, and Gastric Balloon are just a few of the many bariatric options available. These surgeries have proven effective in helping individuals not only shed excess pounds but also improve or resolve obesity-related health conditions. Consultation with a healthcare professional is crucial to determine the most suitable bariatric surgery approach for each individual’s unique circumstances.
