It's not uncommon for older adults, including those with diabetes, to sleep a lot. However, excessive sleepiness can sometimes indicate underlying health issues, especially in elderly individuals. Factors related to age, medications, diabetes management, and overall health can affect sleep patterns.
That said, changes in sleep habits, increased fatigue, or excessive sleep during the day might be a cause for concern, particularly if it is accompanied by other symptoms such as confusion, weight loss, or changes in appetite.
It's essential to discuss these observations with a healthcare provider who can evaluate her overall health, review her medications, and determine if any adjustments or further evaluations are needed. Regular check-ups and open communication about her health will help manage her diabetes and overall well-being.
