Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy is a highly effective surgical procedure designed to help patients achieve significant weight loss by reducing the size of the stomach. This minimally invasive technique not only aids in quick recovery but also marks a pivotal step towards a healthier lifestyle.

What is a Sleeve Gastrectomy?

In the Laparoscopic Sleeve Gastrectomy, a portion of the stomach is surgically removed, leaving a smaller, tube-shaped stomach, commonly referred to as a “sleeve”. This smaller stomach cannot hold as much food as before, which helps drastically reduce the amount you eat without feeling deprived. It also affects the hormones or signals related to hunger and satiety, helping you feel full longer between meals.

Why Opt for Sleeve Gastrectomy?

Sleeve gastrectomy offers a strategic surgical option for individuals seeking significant weight loss through a procedure that is less complex than other bariatric surgeries. It is particularly appealing for patients who may not be good candidates for gastric bypass due to the complexities involved in rerouting the intestines. Instead, sleeve gastrectomy involves reducing the stomach size, making the process simpler and reducing the potential for complications associated with more invasive procedures.

For those hesitant about having a foreign device placed inside the body, as is the case with gastric banding, sleeve gastrectomy presents a reassuring alternative. This procedure eliminates concerns related to foreign objects, such as the risk of slippage or erosion over time.

Sleeve gastrectomy is also valuable as a preliminary step for patients with a very high body mass index (BMI). In cases where the risk associated with gastric bypass surgery is deemed too high due to extreme obesity, sleeve gastrectomy allows patients to start losing weight safely. As they shed pounds and their BMI decreases, they may become suitable candidates for gastric bypass, should further surgery be needed.

This approach not only caters to immediate weight loss needs but also sets the stage for a longer-term health improvement strategy, making it an ideal choice for many looking to manage their obesity effectively and safely.

Benefits of a Sleeve Gastrectomy

Most patients who undergo a sleeve gastrectomy lose approximately 60-65% of their excess body weight. Here are some of the benefits:

  • Effective Weight Loss: Significant reduction in body weight within the first year post-surgery.
  • Improvement in Comorbidities: Conditions such as diabetes, hypertension, high cholesterol, and obstructive sleep apnea show considerable improvement.
  • Enhanced Quality of Life: Improvements in mobility, self-esteem, and overall health contribute to a better quality of life.
  • Reduced Hunger: The surgery impacts hormones that control hunger, helping to curb appetite and control cravings.

Ideal candidates for sleeve gastrectomy are individuals who have a body mass index (BMI) of 40 or higher, or those with a BMI of 35-39 who also have serious weight-related health conditions, such as type 2 diabetes, high blood pressure, or severe sleep apnea.

Most patients lose 60-65% of their excess body weight within the first year after the surgery. Individual results can vary, and success is higher for those who adhere to recommended lifestyle changes including diet and exercise.

After sleeve gastrectomy, you will need to eat smaller portions due to the reduced size of your stomach. Your diet will initially consist of liquids and soft foods, gradually transitioning to solid foods. It’s crucial to eat nutrient-rich foods and avoid calorie-dense but nutritionally poor foods. Regular follow-up visits will include discussions on nutrition to help ensure you are meeting your dietary needs.

The initial recovery period for sleeve gastrectomy usually involves a few days in the hospital. Full recovery, during which you can return to normal activities, typically takes about 4-6 weeks. Patients must follow a specific dietary plan starting with liquids, progressing to pureed foods, and eventually to solid foods.
