Temporary factors, such as illness and the use of certain medications like antibiotics, can affect blood glucose levels and potentially contribute to a temporary increase in HbA1c. Illness, especially if it involves infection and inflammation, can cause temporary insulin resistance and lead to elevated blood glucose levels.
However, a diagnosis of diabetes is typically based on multiple blood glucose measurements and HbA1c results taken over a longer period of time. A single elevated HbA1c measurement may not be sufficient to confirm a diagnosis of diabetes.
It’s encouraging to hear that you made lifestyle and dietary changes, resulting in weight loss and improved blood glucose control. Lifestyle modifications, including weight loss, regular physical activity, and dietary changes, can have a positive impact on blood glucose levels and overall health.
To determine if you have diabetes or if your improved HbA1c level of 5.9% is indicative of normal blood glucose control, it is best to consult with your healthcare provider. They can evaluate your medical history, perform appropriate diagnostic tests, and provide you with a definitive diagnosis and guidance for managing your blood glucose levels moving forward.
Remember, diabetes is a complex condition, and it requires ongoing monitoring, management, and collaboration with healthcare professionals to optimize your health and prevent complications.
