Could hypoglycemia lead to diabetes?

Not usually: Gestational diabetes, obesity, family history of certain types of diabetes are stronger predictors of diabetes later on than episodes of low blood sugar.

High insulin: The common denominator in these two conditions is high Insulin levels (almost always related to excess sugar and carb intake). Initially the high Insulin causes a reactive hypoglycemia, however over time, the chronically high Insulin levels lead to "insulin resistance". When your Insulin no longer works your blood sugars will rise and you develop diabetes. This is 100% preventable wi proper diet.
