Have you had a glucose tolerance test? This takes several hours in the doctor’s office.

Blood sugar is normal and so is A1c on blood testing. These don’t catch hypoglycemia because your blood sugar reacts to what you are eating.

Fasting blood sugar is just one point in time with no food in play. A1c is an average blood sugar over time that does not catch hypoglycemia.

I sure hope your doc gave you this test before suggesting the psychiatrist...
