When Is The Best Time To Check Your Blood Sugar


How Often Should You Check Your Blood Sugar

What Is The Best Time To Check Your Blood Sugar.

As with most things dealing with diabetes, this all depends on your particular body and lifestyle. Work with your care team and doctor to determine the appropriate number of times per day that you should be checking your blood sugars.

Know that not only is everyone different, but peoples needs for more or less frequent checking can change over their lifetime.

For instance, when someone is pregnant, their need for checking goes up immensely, and conversely, if someone with type 2 diabetes weans their way off of insulin, they may need to check less frequently as their likelihood of hypoglycemia is lower without exogenous insulin in their system.

According to the Mayo Clinic, people with type 1 diabetes should at a minimum check between 4 and 10 times per day, and people with type 2 diabetes may only need to check a few times a day , and maybe not at all if they are not on insulin.


But lets be clear: you can check as many times as you need to, and however often youd like . There is nothing wrong with checking more often or whenever you like.

What Are Normal Blood Sugar Levels

You might want to measure your blood sugar before meals to get a baseline, and then two hours after your meal to measure your normal blood sugar level. Your doctor might also suggest measuring blood sugar before bed to be sure you have been eating well throughout the day and can go to sleep with peace of mind.

These are considered within the range of normal:

  • Less than 140 mg/dl if you do not have diabetes.
  • Less than 180 mg/dl if you have diabetes.

Blood Sugar Instability Symptoms

Insulin resistance does not happen all-of-a-sudden. Rather it builds over time and increasingly contributes to health problems. Understanding the signs of poor blood sugar control is the best way to be proactive in this regard. There are several telling signs that your body is not stabilizing blood sugar effectively.

Some of the most common include:


  • Cravings
  • Unstable Energy Levels
  • Sudden Intense Hunger

Most commonly, these symptoms arise simply because someone is consuming too many carbohydrates and sugar throughout the day. This is why I always start with a Keto Metabolic Makeover to kick start a fat-burning state and help people step off the blood sugar rollercoaster. If you are commonly experiencing these symptoms, it is imperative to test blood sugar levels periodically as these symptoms can be effectively controlled by doing so.

  • Do you feel like you’re always short on time? A system that syncs your data wirelessly, without manually entering results, can save time with every test. You may also want to consider a blood glucose meter that gives results quickly, makes it easier to handle test strips, doesn’t require coding, or simplifies lancing or dosing.
  • Would you like to reduce the pain of testing? Choose a system with a lancing device specifically designed for comfort, such as the Accu-Chek FastClix lancing device.

Monitoring Your Blood Sugar

Diabetes: The Best Times to Test Your Blood Sugar

Regular blood sugar monitoring is the most important thing you can do to manage type 1 or type 2 diabetes.

These decisions can help delay or prevent diabetes complications such as heart attack, stroke, kidney disease, blindness, and amputation. Your doctor will tell you when and how often to check your blood sugar levels.

Most blood sugar meters allow you to save your results and you can use an app on your cell phone to track your levels. If you dont have a smart phone, keep a written daily record like the one in the photo. You should bring your meter, phone, or paper record with you each time you visit your health care provider.


Sometimes having high blood sugar can feel like a test you didnt pass. But numbers are just numbers. Think of them instead as information. Did a certain food or activity make your levels go up or down? Armed with that knowledge, you can make adjustments and get closer to your target range more often.

  • Fast, deep breathing.

  • Stomach pain.

DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who havent yet been diagnosed. People with type 2 diabetes can also develop DKA, but its less common.

4. Before bedtime
