Abstract
BACKGROUND
Glycemic variability after Roux-en-Y Gastric Bypass (RYGB) has not been adequately examined in Chinese obese patients with type 2 diabetes (T2D).
OBJECTIVE
We aimed to evaluate glucose variability after RYGB by continuous glucose monitoring (CGM) and then evaluate the remission rate based on the complete diabetes remission criteria combined with normal ranges of CGM for the Chinese population, which we defined as "dual-remission."
SETTING
The study was done at our academic university-affiliated hospital.
METHODS
Over a 3-day period, CGM was performed on 43 Chinese obese T2D patients combined with a mixed-meal test before and 1 year after RYGB. Mean amplitude of glucose excursions (MAGE), standard deviations (SD), and the time that patients' blood glucose levels were≥7.0 mmol/L,≥7.8 mmol/L,≥11.1 mmol/L, and≤3.9 mmol/L within 24 hours was analyzed. Multiple logistic regression analyses were used to identify predictors of "dual-remission."
RESULTS
Complete diabetes remission was achieved in 27 patients (62.8%) 1 year after RYGB. However, MAGE didn't change in the group, and only 18.6% patients met "dual-remission." Compared with patients in the complete remission group, patients in the dual-remission group had a shorter duration of diabetes, younger age, lower glycated hemoglobin (HbA1c) level, and no insulin usage at baseline. Correlation analysis showed MAGE after RYGB was positively correlated with diabetes duration (r = .43, P<.01). Multiple logistic regressions indicated a shorter duration was associated with a higher possibility to achieve dual-remission after adjusting for age, gender, HbA1c, and insulin therapy.
CONCLUSION
Glucose variability can't be effectively improved in most Chinese obese diabetic patients after RYGB. Shorter diabetes duration was associated with higher possibility to achieve "dual-remission."
