Bariatric surgery is one of the most effective treatment options for obesity. Compared with laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery has demonstrated more benefits and surgical risks. Bariatric surgery can result in the decreases in multiple gastrointestinal hormone levels, which can partially explain the mechanisms behind weight loss and resolution of diabetes after bariatric surgery. The management after bariatric surgery should be multidisciplinary and comprehensive, including dietary adjustment, physical exercise, behavioral intervention, and drug therapy.

The excess fatty tissues on the head, neck, thorax, and abdomen of morbid obese patients can impede the patency of the upper airway and impair lung functions. Meanwhile, these patients often have comorbidities such as obstructive sleep apnea, hypoventilation syndrome, chronic obstructive pulmonary disease, and asthma, which may result in difficult airway, intraoperative hypoventilation, and postoperative respiratory depression. Therefore, perioperative airway management for morbid obese patients may pose a big challenge to anesthesiologists. Anesthesiologists should know well about the pathophysiological features of respiratory system and grasp rational management principles, so as to improve the safety and effectiveness of perioperative airway management and optimize the clinical prognosis.

Bariatric surgery has increasingly been applied for patients with severe obesity. By dramati- cally reducing body weight and producing favorable effects on disorders in endocrine metabolism, bariatric surgery has shown to be able to lower the overall mortality. However, this intervention involves a profound change in digestive physiology and may cause nutrition and endocrinal metabolism-related severe complications, which mainly result from the deficiency or unbalance of macronutrients and micronutrients. Therefore, it is necessary to establish a fixed management procedure which includes routine perioperative nutritional consultation, regular monitoring, and early preventive nutritional support, so as to prevent metabolic complications and achieve better outcomes.

An increasing number of patients require body contouring procedures after massive weight loss. Body contouring can bring better quality of life and increase their satisfaction towards weight loss procedures. However, due to the special body status after massive weight loss, the complications of body contouring can be high. This article briefly describes body contouring procedures and summ
