OGTT=Oral Glucose Tolerance Test

I’ve been told that they would tell if you’re hypo or hyperglycemic but I don’t understand that because isn’t type 2 DM when you have high blood glucose levels? Where does the hypoglycemic part come in?

The blood glucose test is ordered to measure the amount of glucose in the blood right at the time of sample collection. It is used to detect both hyperglycemia and hypoglycemia, to help diagnose diabetes, and to monitor glucose levels in persons with diabetes. Blood glucose may be measured on a fasting basis (collected after an 8 to 10 hour fast), randomly (anytime), post prandial (after a meal), and/or as part of an oral glucose tolerance test (OGTT / GTT). An OGTT is a series of blood glucose tests. A fasting glucose is collected; then the patient drinks a standard amount of a glucose solution to “challenge” their system. This is followed by one or more additional glucose tests performed at specific intervals to track glucose levels over time. The OGTT may be ordered to help diagnose diabetes and as a follow-up test to an elevated blood glucose.
If hypo you will go low !!!
Hypoglycemia is characterized by a drop in blood glucose to a level where first it causes nervous system symptoms (sweating, palpitations, hunger, trembling, and anxiety), then begins to affect the brain (causing confusion, hallucinations, blurred vision, and sometimes even coma and death). An actual diagnosis of hypoglycemia requires satisfying the “Whipple triad.” These three criteria include:
Documented low glucose levels (less than 40 mg/dL (2.2 mmol/L) often tested along with insulin levels and sometimes with C-Peptide levels)
Symptoms of hypoglycemia
Reversal of the symptoms when blood glucose levels are returned to normal.
Primary hypoglycemia is rare and often diagnosed in infancy. People may have symptoms of hypoglycemia without really having low blood sugar. In such cases, dietary changes such as eating frequent small meals and several snacks a day and choosing complex carbohydrates over simple sugars may be enough to ease symptoms. Those with fasting hypoglycemia may require IV glucose if dietary measures are insufficient.
