Objective To investigate the effect of laparoscopic Roux-en-Y gastric bypass(LYGB) on body fat distribution,and relationship between the changes of body fat distribution and improvement of insulin resistance.Methods A total of 65 patients with type 2 diabetes who underwent LYGB were selected for a retrospective analysis.Metabolic parameters,anthropometric measurements,body composition and fat distribution measured by dual-energy X-ray absorptiometry (DEXA) were collected separately before and 6 months post LYGB.All data of pre-and postoperation were compared with pair t test,Pearson correlation analysis was used to evaluate correlation of two variables.Results Weight,body mass index,waist circumference,waist-to-hip ratio,triglyceride,fasting plasma glucose,fasting insulin and homeostatic model assessment for insulin resistance (HOMA-IR) were significantly decreased in 6 months after surgery (P ＜ 0.05).Total fat mass,body fat mass of trunk,upper and lower limbs decreased significantly (P ＜0.05).Percent fat mass at the whole body,Android region,upper and lower limbs decreased significantly (P ＜0.05).After 6 months postoperatively,abdominal obesity indices waist circumfernce decreased from (98.10±13.03) cm to (91.60±7.68) cm (P＜0.01) and percent fat mass at the Android region decreased from (35.71 ±10.24)％ to (29.44 ± 12.11) ％ (P＜0.05),HOMA-IR decreased from 3.62 ± 5.18 to 1.79 ± 1.52 (P ＜ 0.05).The improvement of postoperative insulin resistance is positively correlated with the changes in waist circumference (P ＜0.01) and percent fat mass of Android region (P ＜0.05).Conclusions The body fat distribution changes after LYGB,change of abdominal fat distribution is positively correlated to the improvement of insulin resistance.
RESUMEN
Vitamin D plays an important role in cellular differentiation and Calcium phosphate metabolism.At the same time,the role of Vitamin D in glycolipid metabolism had attracted a lot of attention.Bariatric surgery is an effective treatment to achieve therapeutic endpoints for comorbidities associated with obesity,but vitamin D status is always insufficient before and after surgery.In this review,the author aim to (1) discuss the deficiency of vitamin D in bariatric patients,(2) to summarize the impact of vitamin D on glycolipid metabolism and the outcome of bariatric surgery,(3) to discuss the supplementation for the deficiency of vitamin D.
RESUMEN
Type 2 diabetes mellitus (T2DM) usually becomes complicated and unmanageable when combing with metabolic syndromes of obesity,hypertension and hyperlipidemia.Medical treatment generally adopts non-surgical management,such as diet control,exercise and oral medications; surgical treatment can improve the condition of patients with T2DM and the metabolic syndromes.In this article,the multi-disciplinary treatment of a patient with T2DM and obesity in the Third Xiangya Hospital of Central South University was analyzed,so as to provide a new way for the treatment of this disease.
