Clinical Trial Summary

Obesity is a chronic disease in which accumulation of excess body fat can result in impaired health. In cases of severe obesity, weight loss surgery can be necessary as a treatment. There are different forms of surgery but the common basic principle is to restrict food intake and decrease the absorption of food in the stomach and intestines. As a consequence, there is a higher risk of developing nutrient deficiency after surgery and supplementation of protein, vitamins, and minerals can be necessary. This study evaluates intakes of protein, vitamins, and minerals in patients with weight loss surgery and compares them to recommended intakes. Further, this study looks at the role of age, sex, and socioeconomic status in this context.


Description:

Obesity is defined by the World Health Organization as abnormal or excessive fat accumulation that may impair health. These days, bariatric surgery is considered the most effective treatment of morbid obesity. In the last decade, the number of bariatric surgeries performed worldwide constantly increased. Common bariatric surgery procedures include gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. After surgery, weight loss is induced by a reduced food volume the stomach can hold, malabsorption of nutrients, or by a combination of both mechanisms. In consequence, patients with bariatric surgery have an increased risk of developing nutrient deficiency. Therefore, guidelines recommend supplementation of critical nutrients, i.e. protein, vitamins, and minerals, after bariatric surgery. This study assesses intake of these nutrients in patients with bariatric surgery based on the recommendations provided by the German S3 Guideline Group on the Surgical Treatment of Obesity and Metabolic Diseases. In particular, this study assesses the association of therapy adherence with age, sex, and socioeconomic status.
