When should I call my healthcare provider about my blood sugar level?

Proper blood sugar ranges are different for each person and can change throughout the day. Your healthcare provider will tell you what your range should be. Call your healthcare provider if one of the following occurs:

  • Your blood sugar test results are higher than usual (more than 100 mg/dl above your usual results) for more than 2 days for an unknown reason.
  • Your blood sugar level is low (less than 70 mg/dl) more than 2 times a week.
