Abstract

Morbid obesity is defined as excess weight or body fat to an extent that may have negative effects on health. It increases the risk of developing heart disease, diabetes, hypertension, and obstructive sleep apnea. Excessive food intake and lack of physical activity are thought to explain most cases of obesity; others are associated with genetic disorders, organic diseases, and psychiatric conditions. Obesity is defined as body mass index (BMI) 30 kg/m2 or higher and is further sub-classified into three groups: BMI 30.0 to 34.9 kg/m2 is class I, 35.0 to 39.9 kg/m2 is class II and greater than or equal to 40 is class III. The goal of obesity treatment is to reach and maintain a healthy weight. The primary treatment consists of diet and physical exercise; however, maintaining weight loss is difficult and requires discipline. Medications such as orlistat, lorcaserin, and liraglutide may be considered as adjuncts to lifestyle modification. One of the most effective treatments for obesity is bariatric surgery. There are several bariatric surgery procedures, including laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, sleeve gastrectomy, and biliopancreatic diversion with duodenal switch. Sleeve gastrectomy is the most commonly performed bariatric surgery worldwide. It is performed by removing 75% of the stomach, leaving a tube-shaped stomach with limited capacity to accommodate food. Here, we present the case of an obese patient who undergoes laparoscopic sleeve gastrectomy.
