How does The Gastric Sleeve Surgery work? By Gerald Witt on September 11, 2021

gastric sleeve surgery in MexicoAs everybody knows, The Gastric Sleeve is a minimally invasive bariatric procedure that restricts the volume of food a person can eat and decreases the appetite but many prospective patients wonder…how does gastric sleeve surgery work?

The Gastric Sleeve Surgery, also known as laparoscopic sleeve gastrectomy or the vertical sleeve gastrectomy,  is a bariatric surgery where the surgeon makes several very small incisions in the abdominal region of the stomach and inserts a laparoscope with a very small camera which sends pictures to a monitor in the operating room so that they are able to perform the surgery without having to open up the patient. The gastric sleeve surgery offers a lasting solution to effective weight loss by removing between 60 % to 80% portion of the stomach using this minimally invasive surgical technique, leaving behind a new small sleeve or tube of the stomach and making changes to the patient’s stomach and digestive system that limits how much food they can eat and how many nutrients they absorb, leading to weight loss.  The minimally invasive surgery also allows for a quicker recovery and less pain post-surgery.

The way Gastric Sleeve Surgery work is:

  • Restriction: Since the stomach is made smaller, there is much less room to hold food, as such the patients cannot eat as much food as they used to and feel fuller much quicker once the new stomach is at capacity.


  • A physiologically diminished appetite: With the removal of the upper curvature of the stomach, the section of the stomach that creates the hunger hormone known as grehlin is removed, allowing the patient’s body to decrease the patient's appetite.


In addition, Gastric Sleeve Surgery may improve weight-related diseases or medical conditions, such as sleep apnea, Type 2 diabetes, high blood pressure, heart disease, and more. Many patients who undergo Gastric Sleeve Surgery and who had to take a lot of medications prior to surgery, may experience a great reduction in the number of those medications and also may improve their overall health.

Taking care of your body is not just about the way you look, it goes further, it is about health and life. Being overweight can cause life-long severe diseases and psychological as well as emotional problems. Gastric Sleeve Surgery is a weight loss option for people with these issues and is an attempt to help the patient succeed on their weight-loss journey. Bariatric surgery however is only the start of the process and as a tool is a good beginning. As the patient starts losing weight, they become healthier and live fuller and more active lives, however, it is the responsibility of the patient to follow through with their doctor's advice and post-surgery instructions including a healthy long-term diet until the patient reaches their goal weight.

Obviously, as part of any bariatric surgery process, all patients must stick to a healthy diet and physical activity such as exercise or a hobby that involves physical activity. People need to realize that the surgery will work long term only if they commit to their weight loss and work hard to change their habits and lifestyle permanently.

Gastric Sleeve as with any other weight loss surgery is major surgery and not everybody is a candidate for the procedure. It is essential that patients who are willing to have a weight loss surgery, undergo a thorough evaluation to determine if they are candidates or not with their bariatric surgeon.
