A fasting blood glucose of 131 mg/dL is above the
diabetes diagnostic threshold, but a single reading alone does not necessarily establish a diagnosis. Diabetes is generally confirmed with a repeat abnormal test unless there is unequivocal hyperglycaemia.
Next Steps
Please get a laboratory fasting plasma glucose and
HbA1c. If required, your doctor may advise a repeat fasting glucose or 75-g OGTT to clarify the diagnosis.
If the HbA1c and repeat glucose are normal or in the prediabetes range, medication may not be necessary initially and lifestyle modification can be very effective.
Health Tips
For now, don't panic and don't start
diabetes medication on your own. Reduce sugary drinks, sweets and refined carbohydrates, increase vegetables/fibre, maintain a healthy weight and aim for regular physical activity (such as brisk walking).
Fasting 131 does not mean “you definitely have diabetes” from one reading. Confirm it properly first.
