How is reactive hypoglycemia diagnosed?
Diagnosis is difficult because there are no clear diagnostic criteria. Your doctor may: • ask you about signs and symptoms • test your blood glucose while you are having symptoms (The doctor will take a blood sample from your arm and send it to a laboratory for analysis. A personal blood glucose monitor cannot be used to diagnose reactive hypoglycemia.) • check to see whether your symptoms ease after your blood glucose returns to 70 mg/dl or 3.5 mmol/L or above (after eating or drinking)If your doctor uses an oral glucose tolerance test (OGTT) to diagnose hypoglycemia you have to continue it for at least 3-4 hours (the normal time is 2 hours). Your insulin levels would be measured at the same time.
