Glycated hemoglobin (HbA1c) levels reflect average blood glucose control over the preceding two to three months. Establishing optimal HbA1c goals for older adults requires a nuanced approach, balancing the benefits of glycemic control with the potential risks of hypoglycemia and other treatment burdens. For instance, a less stringent goal may be appropriate for an individual with multiple comorbidities and limited life expectancy, while a tighter goal may be suitable for a healthier individual with a longer life expectancy.
Maintaining appropriate glycemic control in older adults is crucial for reducing the risk of long-term diabetes complications, such as microvascular damage affecting the eyes, kidneys, and nerves. However, overly aggressive glycemic control can increase the risk of hypoglycemia, which can lead to falls, confusion, and other adverse events. Historically, managing blood glucose in older adults has presented challenges due to age-related physiological changes and the presence of other medical conditions. Evolving research and clinical experience continue to refine best practices for individualizing glycemic targets in this population.
