After more exercise than usual, how long can blood sugar stay lower than normal?

Up to 24 hours, including overnight.

  1. Up to 24 hours ✔
  2. Only during the workout
  3. Only for about 5 minutes

Why: Activity makes cells more sensitive to insulin, which is good, but it can lower blood sugar for hours afterward. Check before, during and after, and ask your care team how to prevent lows.

Huh, didn't know that: NIDDK suggests aiming for at least 150 minutes of moderate activity, like brisk walking, each week.
