Laparoscopic Sleeve Gastrectomy is one of the most commonly performed and effective bariatric procedures worldwide. It is a minimally invasive weight-loss surgery designed to help patients achieve significant and sustained weight reduction while improving obesity-related metabolic conditions. The procedure is particularly suited for individuals with morbid obesity, severe obesity with comorbidities, and those seeking a durable yet anatomically straightforward bariatric option.

During sleeve gastrectomy, approximately 70–80% of the stomach is surgically removed, leaving behind a narrow, tube-shaped stomach known as a “sleeve.” This significantly reduces the volume of food the stomach can hold, leading to early satiety and reduced calorie intake. Importantly, the procedure also removes the portion of the stomach responsible for producing ghrelin, the hormone that stimulates hunger. As a result, patients experience a marked reduction in appetite and food cravings.

Unlike malabsorptive procedures, sleeve gastrectomy does not alter the intestines. This allows food to follow its normal digestive pathway while still delivering powerful metabolic benefits. Because intestinal continuity is preserved, nutrient absorption remains largely intact, making the procedure nutritionally safer for many patients when combined with proper supplementation and follow-up.

Laparoscopic sleeve gastrectomy is performed using small keyhole incisions, which minimizes surgical trauma, reduces pain, shortens hospital stay, and accelerates recovery. Most patients are able to resume normal daily activities within a few weeks. The minimally invasive nature of the procedure also lowers the risk of complications such as infection and hernia formation.
Patients typically achieve 60–70% excess weight loss within 12–18 months after surgery. In addition to weight reduction, sleeve gastrectomy leads to significant improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, obstructive sleep apnea, fatty liver disease, and joint pain. Many metabolic benefits begin within weeks of surgery, even before substantial weight loss occurs.

Long-term success following sleeve gastrectomy depends on comprehensive care. Patients undergo pre-operative evaluation, nutritional counseling, psychological assessment, and metabolic screening. Post-operative follow-up focuses on dietary progression, vitamin supplementation, physical activity, and behavioral modification to ensure sustainable results.
Laparoscopic sleeve gastrectomy is not a cosmetic procedure but a medically proven treatment for obesity and metabolic disease. When combined with lifestyle changes and multidisciplinary support, it offers patients a safe, effective, and life-changing path toward long-term health improvement.
