Regular exercise improwises insulin sensitivity, cardiovascular health, and psychological well-being. However, it requires careful glucose monitoring and insulin adjustment to prevent exercise- induced hypoglycemia or, less common, hyperglycemia.

Increasingy, continuous glucose monitoring (CGM) systems such as Dexcom or Libre provide real-time glucose readings and trend information, enabling more proactive management.
