Morbid obesity is defined as having a body mass index (BMI) above 40 or having a BMI of 35 and comorbidities along with obesity. Bariatric surgeries can be grouped into three. These are restrictive surgeries, malabsorption (impairing absorption) surgeries, and both restrictive and malabsorption surgeries. In bariatric surgery, restrictive surgeries such as vertical band gastroplasty (VGB), adjustable gastric banding (AGB) surgeries, malabsorption surgeries such as biliopancreatic diversion (BPD)/duodenal switch (DS) surgeries, and both restrictive and malabsorption surgeries such as Roux-en-Y gastric bypass (RYGB) surgeries, are commonly performed. Post-bariatric surgery care should include a multidisciplinary team consisting of a surgeon, an endocrinologist, a psychiatrist, a dietitian, and a nurse specializing in bariatric surgery. Nursing care after obesity surgery is evaluated as early postoperative care (1-3 days) and late postoperative care. Close observation, careful and complete evaluation are important in the specialist nursing care of bariatric surgery patients. In bariatric surgery, patients are provided with routine post-operative nursing care such as oxygen and hemodynamic monitoring, pain management, mobilization, wound care, deep vein thrombosis prophylaxis, early and frequent ambulation, drain care, fluid balance nutrition, training, and emotional support.
