However, a prospective study comparing post-RYGB individuals with or without T2DM vs. non-operative controls (n = 7 per group) identified significant differences between groups, with individuals without diabetes exhibiting high GV and the longest duration of hypoglycaemia compared to people with diabetes, possibly due to improved insulin sensitivity and the preserved effect of endogenous incretins [81]. The gene discussed is INS; the disease is Hypoglycemia.
