When to Check Blood Sugar Level?

Talk to you doctor or healthcare providers about the best times to check your blood glucose, as optimal times vary by person.

Some options include:

  • after fasting (after waking or not eating for eight to 12 hours) or before meals
  • before and after meals, to see the impact that the meal had on your blood sugar
  • before all meals to decide how much insulin to inject
  • at bedtime

Bring a record of your blood sugar results to doctors’ appointments so you can review it and make changes to your treatment if necessary.
