Obesity and overweight are defined as abnormal or excessive accumulation of adipose tissue that can have a negative impact on health. Today, the most commonly used methods of measuring adipose tissue are body mass index (BMI) and waist circumference. The main risk factors for the development of obesity are diet and sedentary lifestyle along with socioeconomic and genetic factors. Obesity is associated with an increased risk of a number of diseases, and the level of risk increases with a BMI over 25 kg/m². Among the most significant risk groups are metabolic and cardiovascular risks. The main non-invasive approaches to the therapy of obesity are dietary therapy, physical activity, psychotherapeutic approaches and pharmacotherapy. A change in diet with a reduction in caloric intake should be the basis of any weight loss, and physical activity is also crucial. Intragastric balloon therapy is a minimally invasive approach where a silicone balloon is temporarily inserted into the stomach, which leads to a decrease in appetite. The surgical procedures performed to manage obesity are collectively referred to as bariatric surgery. Criteria for bariatric surgery are BMI over 40 kg/m² or BMI over 35 kg/m² with the presence of comorbidities which are severely endangering the patient’s life. Bariatric procedures are divided into restrictive, malabsorptive and combined procedures. Adjustable gastric banding is a restrictive procedure in which a silicone band is placed around the proximal part of the stomach, forming a pre-stomach of reduced volume. Sleeve gastrectomy is a restrictive procedure in in which the majority of the greater curvature of the stomach is removed and a tubular stomach is created. Weight loss in sleeve gastrectomy is also supported by the changes in the secretion of ghrelin. Roux-en-Y gastric bypass and biliopancreatic diversion with duodenal switch are procedures that combine a restrictive and malabsorption mechanisms and they both involve reduction of stomach volume along with bypassing parts of the small intestine. Excessive weight loss after bariatric procedures often leaves behind a significant amount of flabby, stretched skin and subcutaneous tissue. 70-90% of patients express a desire for plastic surgery after bariatric surgery. Body contouring refers to a series of plastic and reconstructive procedures covering the entire body with the ultimate goal of removing the difficulties caused by excess skin and increasing the quality of life in general.
