Is a fasting glucose of 110 bad?
A fasting glucose of 110 mg/dL (6.1 mmol/L) is in the prediabetes range, which runs from 100 to 125 mg/dL. Diabetes starts at 126. One reading does not settle it.
The next step is an HbA1c, or a second fasting test on another day, because a poor night, an illness or a late meal the evening before can push one morning reading up.
If it is confirmed, the same changes that bring down an A1c apply: weight, 150 minutes of walking a week, and less sugar in drinks.
See a doctor promptly if
- Excessive thirst, passing large amounts of urine, blurred vision or unexplained weight loss. These suggest blood sugar is already well above the prediabetes range
- Nausea, vomiting, abdominal pain, deep rapid breathing or a fruity smell on the breath: go to an emergency department
- A random blood glucose of 200 mg/dL (11.1 mmol/L) or higher, or a fasting glucose of 126 mg/dL (7.0 mmol/L) or higher
- New numbness, burning or pins and needles in both feet
- A wound on the foot that is not healing, or a skin or genital infection that keeps returning
