In recent years, obesity has become the number one non-communicable disease in history. It has risen sharply worldwide, including in developing countries. It is a major risk factor for cardiovascular disease, diabetes and cancer. Algeria is no exception to this rule. Consequently, this rise in the prevalence of obesity in our society systematically includes an increase in the number of obese patients requiring surgical intervention for various reasons. Managing these patients in anaesthesia is a special challenge, requiring technical resources and knowledge to optimize the results of preoperative, intraoperative and postoperative management.
