See the Discount ›Does age change normal?
The diagnostic cutoffs are the same for adults of all ages, but risk of prediabetes rises with age (NIDDK). See blood sugar after 50.
Home meters and continuous monitors
Home glucose meters and wearable monitors give quick readings, but diagnosis is based on lab tests your doctor orders. If you use a meter, wash your hands first, follow the instructions and record the time of each reading relative to meals. Bring your log to appointments. See high morning readings and A1C chart.
If your numbers are creeping up
Talk to your doctor, start the habits in how to lower blood sugar naturally, and consider daily support. MetaGlucent is made to support healthy blood glucose levels already in the normal range (NCCIH discusses its key ingredients).
