In addition, patients with endogenous hyperinsulinism had lower HbA1c levels (they probably had lower mean blood glucose levels in the 2–3 months before the test), and higher BMI (possibly because of the need to frequently eat carbohydrates to correct hypoglycemia, as well as due to the anabolic effect of insulin itself) [30]. The gene discussed is INS; the disease is Hypoglycemia.
