For people with diabetes, it is generally ideal to maintain consistent blood glucose levels within a target range as much as possible. Fluctuations in blood glucose levels can be challenging for diabetics to manage and may increase the risk of complications associated with diabetes in the long run. The target range may vary depending on individual factors and the advice of the healthcare provider, but in general, it is important to avoid both low and high blood glucose levels.
In your example, if a diabetic individual's average glucose level is 8 mmol/L on one day and 10.3 mmol/L on average the next day, it indicates significant fluctuations in blood glucose levels. This fluctuation might not be ideal and could potentially increase the risk of short-term and long-term complications.
Consistently high glucose levels (like the 10.3 mmol/L average) can contribute to various health issues, including damage to blood vessels, nerves, and organs. Consistently low glucose levels can also be problematic and lead to symptoms of hypoglycemia, which can be dangerous if not addressed promptly.
Diabetics often aim to keep their blood glucose levels as stable as possible by managing their diet, medication (if prescribed), physical activity, and lifestyle choices. Continuous glucose monitoring (CGM) devices can be helpful in tracking and managing blood glucose levels more effectively.
It's essential for diabetics to work closely with their healthcare team to establish an appropriate target range for their blood glucose levels and to develop a personalized management plan to achieve better control and reduce fluctuations. Regular monitoring, adherence to prescribed medications or insulin regimens, and lifestyle adjustments can all contribute to better glucose level management and overall health for people with diabetes.
