Gastric Sleeve Surgery

Gastric Sleeve Surgery for Weight Loss

Gastric sleeve surgery, also known as a laparoscopic sleeve gastrectomy, is a highly effective bariatric weight loss surgery that can help patients achieve significant weight loss and improve their health.

Typically, this surgery is done laparoscopically with minimally invasive technology to reduce recovery time and complications.

This procedure does not involve bypassing the intestines or nutrient absorption complications, making it an attractive bariatric surgery option for many.

The Procedure

During a gastric sleeve procedure, surgeons use minimally invasive technology to reshape the stomach.

Stomach Reduction: Approximately 75 percent of the existing stomach is removed during the procedure, creating a narrow, tubular stomach resembling a shirt sleeve.

Depending on the surgeon and patient, the remaining stomach measures from one to five ounces. This reduced stomach size serves as a natural restriction, limiting the amount of food and calories the patient can consume.


Hormonal and Neurological Changes: The nerves to the stomach and the outlet valve remain intact so that the functions of the stomach are preserved while drastically reducing the volume.

The portion of the stomach that is removed also plays a crucial role in altering hormonal and neurological messaging systems related to appetite control in the brain. This contributes to reduced feelings of hunger, further aiding in weight loss.

Advantages of Gastric Sleeve Surgery

This laparoscopic surgical approach offers several advantages:

  • Normal Stomach Function: The remaining stomach continues to function normally, allowing most food items to be consumed in small amounts.
  • Hunger Hormone Reduction: The portion of the stomach that produces hormones that stimulate hunger is removed, helping patients manage their appetite.
  • No Dumping Syndrome: Unlike some other weight loss surgeries, gastric sleeve surgery preserves the pylorus, or the opening of the stomach, minimizing the risk of dumping syndrome, a condition that can cause discomfort after eating.
  • Reduced Risks: By avoiding intestinal bypass, the procedure significantly lowers the chances of complications like an ulcer, intestinal obstruction, anemia, osteoporosis, protein deficiency, and vitamin deficiency.
  • Effective for Various BMI Levels: Gastric sleeve surgery has been shown to be effective for high BMI patients as a first-stage procedure and also as a single-stage procedure for those with lower BMIs.
  • Suitable for High-Risk Patients: This procedure may be a suitable option for individuals with conditions such as anemia, Crohn's disease, or other high-risk factors that would make the patient high risk for intestinal bypass procedures.

What is Laparoscopic Surgery?

Gastric sleeve surgery is typically performed laparoscopically, a minimally invasive approach.

During laparoscopic surgery, a small camera is inserted into the abdomen, providing the surgeon with a clear view of the procedure on a video monitor. This approach offers several benefits:

  • Less Invasive: Laparoscopic surgery requires smaller incisions, reducing post-operative pain and complications.
  • Faster Recovery: Patients tend to recover more quickly and can return to their pre-surgical activity levels sooner.
  • Reduced Complications: Fewer wound complications such as infections or hernias are associated with laparoscopic surgery.

Gastric sleeve surgery offers numerous advantages and can be an effective option for individuals seeking significant weight loss and improved health.

However, as with any weight loss procedure, not all patients are candidates for this approach. Adherence to a tailored post-surgery plan, including dietary, exercise, and emotional support, is essential for lasting success and overall well-being.

If you are considering this surgery, consult with your provider to discuss your specific needs and suitability for the procedure.
