While each person’s specific blood sugar monitoring schedule is personal, checking blood sugar throughout the day is one of the best ways to ensure that your levels are in a safe target range. Blood glucose tends to peak after meals. This may leave you wondering, how long should I wait after eating to check my blood sugar? Finding the answer can help you safeguard your health and better manage your diabetes.

When Should I Check My Blood Sugar?

How often you check your blood sugar will depend on the type of diabetes you have and your treatment plan. Some of the most common times to check include the following:

  • When you first wake up
  • Before a meal
  • After a meal
  • Before snacks
  • Before exercise
  • After exercise

You should also check your blood sugar if you experience symptoms of low or high blood sugar. Symptoms to look out for include fatigue, headaches, blurred vision, dry mouth, shakiness, and sweating.

Be sure to speak with your healthcare provider to ensure that you fully understand your monitoring schedule.

How Long Should I Wait After Eating to Check My Blood Sugar?

“How long should I wait after eating to check my blood sugar?” is one of the most common questions people have when they start self-monitoring blood sugar at home. Healthcare practitioners often recommend that people with diabetes wait two hours after the beginning of a meal to check blood sugar.

After eating, blood sugar levels rise as the body begins to break down food into sugars and tend to peak one to two hours after eating. People without diabetes will produce enough insulin to bring their blood sugar level back down from its post-meal high.

People living with type 1 diabetes do not produce insulin, and people with type 2 diabetes do not produce enough insulin or are resistant to the action of insulin. This means blood sugar may remain elevated longer. Typically, checking blood sugar two hours after a meal allows enough time for the body to digest the food from your meal and allow insulin to act. However, you should always speak to your healthcare provider to determine how long of a wait is appropriate for you.

How to Prevent Post-meal Spikes

Taking fast-acting prandial, or mealtime, insulin 20–30 minutes before eating a meal can reduce blood sugar spikes because the insulin will begin to work when glucose from food starts to enter the bloodstream. Additionally, a portioned diet rich in foods like vegetables, whole grains, lean protein, and fruit can cause a slower rise in blood sugar and help prevent post-meal spikes. Your healthcare provider can help you determine what strategy is best for you.

Blood Glucose Testing Made Simple

Checking blood sugar levels before and after meals (known as paired testing) can help you determine how different foods affect them and whether your diabetes management plan needs to be adjusted. Whether you’re out to eat at a restaurant or eating a meal at home, having the right tools to stay on top of blood sugar monitoring is key.
