Is gastric sleeve safe?

Yes, it has been demonstrated that gastric sleeve surgery is a safe and also effective procedure for losing weight. When reviewing the risks associated with gastric sleeve surgery versus developing severe obesity-related health complications, gastric sleeve surgery is often determined to be the right option.

Gastric Sleeve Safety In Numbers

In a study conducted by Stanford University on approximately 270,000 bariatric surgical procedures performed over more than a decade, researchers discovered that when compared with gastric bypass and gastric banding, sleeve gastrectomies produced the lowest complication rate, 0.96 percent. Furthermore, analysis of the collected data for outcomes after bariatric surgery demonstrated a 30-day postoperative mortality rate of 0.08 percent. Patients who underwent sleeve gastrectomy observed a 30 percent excess body mass index loss (BMI).

When reviewing the risks associated with gastric sleeve surgery - one of the most popular bariatric surgeries in the modern era - versus developing severe obesity-related health complications, gastric sleeve surgery is often determined to be the right option. If you do not struggle with a co-morbid disease, be aware that obesity-related conditions like cardiovascular disease, type 2 diabetes, and atrial fibrillation put you at a significantly higher risk than surgery, particularly gastric sleeve, which is considered a relatively safe procedure.

Potential Complications

All surgical procedures have risks, and as any stomach operation for obesity is considered a major operation, it has significant risks and complications associated with it. Gastric sleeve complications can include:

  • excessive bleeding
  • infection
  • negative reaction to anesthesia
  • blood clots
  • breathing problems
  • leaks in the staple line where the stomach has been removed
