Change of Adipose Tissues and Triglyceride After Bariatric Surgery or Life-style Intervention
The study is aimed * To quantify the change of adipose tissues, triglyceride in liver and pancreas and cholesterol after lifestyle intervention or bariatric surgery. * To test the hypothesis that Brown fat is an independent biomarker for the development of Non Alcoholic Fat Liver Disease (NAFLD) * To study the association among Brown fat, NAFLD and obesity.
Conditions studied
Non-Alcoholic Fatty Liver Disease, Obesity, Morbid, Brown Fat, Metabolic Disease, Diabetes Mellitus, Insulin Resistance, Abdominal Subcutaneous Fat
About this study
The study is aimed * To quantify the change of adipose tissues, triglyceride in liver and pancreas and cholesterol after lifestyle intervention or bariatric surgery. * To test the hypothesis that Brown fat is an independent biomarker for the development of Non Alcoholic Fat Liver Disease (NAFLD) * To study the association among Brown fat, NAFLD and obesity.
Interventions
- Procedure: Bariatric surgery — Use of the normal bariatric surgery procedures commonly conducted in our hospital, such as: Laparoscopic Roux-en-Y gastric bypass (RYGB) and Laparoscopic sleeve gastrectomy (LSG)
- Behavioral: Dietitian led life style modification intervention — Intensive 6 months life style changes supervised by diatitians.
- Behavioral: Conventional care (control) — receive routine care
Primary outcomes
- Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery (one year)
- Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery 2 (one year)
- Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery- 3 (one year)
- Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery- 4 (one year)
- Use of modified Dixon Magnetic Resonance Imaging method to assess the relationship between Brown Adipose Tissue and Non Alcoholic Fatty Liver Disease (one year)
- Blood biochemistry for assessing β-cell function and insulin resistance (IR) (one year)
- Blood biochemistry- 1 (one year)
- Blood biochemistry- 2 (one year)
