I havent eaten anything in over 12 hours and my blood sugar is 112. could this mean hyoglycemia, or prediabetes?

1. is you tester accurate. Finger ones are not always. 2. Not hypoglycemia by this number. 3. Not prediabetes- requires a Standard GTT done properly. Or getting pregnant may bring our diabetes sometimes but do not recommend this as a test.

You are not hypoglycemic. To diagnose pre-diabetes you need to be tested for fasting plasma glucose at an accredited laboratory. If this reading was from a glucometer, it may not be accurate. Talk to your doctor about getting your fasting plasma glucose done at a laboratory and also an A1c test. Wish you good health!
