Overall, bariatric surgery had a positive impact on weight loss and resolution of hyperglycemia for every subject included in this study, leading to significant decreases of 22% in mean weight (p = 9.1×10−7), 21.0% in mean BMI (p = 9.9×10−7), 42% in fasting plasma glucose (p = 8.6×10−4), 26% in mean glycosylated hemoglobin (HbA1C) content (p = 5.9×10−4), and 80% in fasting plasma insulin (p = 0.042). Here, INS is linked to Hyperglycemia.
