The timing for checking blood sugar levels depends on your health condition and treatment plan. Here are some general guidelines:

  • Fasting Blood Sugar: Check first thing in the morning before eating or drinking anything.
  • Before Meals: Check 1-2 hours before meals to understand your baseline levels.
  • After Meals: Check 1-2 hours after meals to see how food affects your blood sugar.
  • Before and After Exercise: Check before and after physical activity to monitor the impact of exercise.
  • Before Bed: Check before sleeping to ensure your levels are stable overnight.

For people with diabetes, frequent monitoring is crucial. Consult your healthcare provider for a personalized testing schedule.
