Clinical and Metabolic Characterization of Long-term Courses of Obesity Patients — AdipFollowup  

Obesity Clinical Trial

Official title: Klinische Und Metabolische Charakterisierung Der Langzeitverläufe Von Adipositas-Patienten Mit Vergleich Von Bariatrisch Operierten zu Nicht Operierten Patienten

Status Completed

Clinical Trial Summary

The long-term courses after bariatric surgery are not sufficiently known. Furthermore there is a heterogeneity in postoperative responses. The aim of this study is to investigate the glycemic course (prediabetes, development of diabetes) of patients with obesity (BMI>=35 kg/m2) who had undergone bariatric surgery compared to patients with obesity who have not. A further aim is to investigate predictors of weight development, development of body composition and insulin sensitivity of patients who had undergone bariatric surgery compared to obesity patients who have not undergone bariatric surgery. The long-term courses after different surgical procedures (Roux-Y vs Sleeve) will be compared. In this study 300 patients with obesity who had been metabolically characterized in a previous study will be recruited. These patients are examined (medical history, physical examination including ECG, BIA, weight, height) and metabolically characterized. Participants without diabetes undergo a glucose tolerance test and fasting blood sampling will be performed in participants with diabetes. All patients complete questionnaires to activity, nutrition, life quality, impulsiveness, depression and eating behavior. Randomly selected participants will be offered an abdominal fat tissue biopsy. When consent is given, this will be performed at least two days after the glucose tolerance test.
