Do you test your fasting blood glucose?  Do you know your target? Comment below. No judgement here! 

Fasting blood glucose levels can give us an idea of blood sugar control in individuals with type 2 diabetes. A fasting blood glucose test measures the level of glucose in the blood after a period of fasting, usually eight hours or overnight. The test provides an indication of how well the body is able to regulate blood sugar levels during periods of fasting.

For individuals with type 2 diabetes, the recommended fasting blood glucose target is between 4.0 to 7.0 mmol/L. This target may be adjusted based on an individual's age, health status, and other factors. The post-meal or post-prandial blood glucose target is between 5.0 to 10 mmol/L.

It is important to discuss your fasting blood glucose targets with your doctor and work together to determine what is appropriate for you. Your fasting blood glucose targets may be adjusted based on your HbA1c target, which provides an indication of how well blood sugar levels have been controlled over time.

Regular monitoring of fasting blood glucose levels is important for individuals with diabetes to ensure that blood sugar levels are well controlled. Monitoring can help identify trends and patterns in blood sugar levels and enable adjustments in diet, exercise, and medication as needed.

If you do not know your fasting blood glucose target, it is essential to discuss this with your doctor. Understanding your targets and working to achieve them can help reduce the risk of developing diabetes-related complications, such as nerve damage, kidney damage, and eye damage.

Remember that achieving your fasting blood glucose target can be challenging and may require lifestyle changes and medication adjustments. It is essential to work with your healthcare team, which includes a registered dietitian, to develop a plan that is tailored to your individual needs and circumstances. Regular monitoring, open communication with your health care team and a commitment to self-care can help you achieve your fasting blood glucose target and improve your overall health.
