Obesity is a disease of energy homeostasis with accumulation of excessive fat leading to negative health effects associated with increased morbidity and mortality. The World Health Organization (WHO) estimates approximately 700 million people worldwide in the obese category. Life expectancy due to obesity is decreased by 6–7 years. A body mass index (BMI) of 30–35 kg/m2 reduces life expectancy by 2–4 years, while BMI >40 kg/m2 reduces life expectancy by 10 years. In this manuscript, we will review the global updates on the burden of obesity, current management of obesity, evolution of bariatric endotherapy, various aspects of bariatric endotherapy, and literature review of the data supporting the bariatric endotherapy.
