How to Measure Your Blood Sugar – Mayo Clinic Patient Education

If you take certain medication, like insulin or sulphonylureas, checking your blood sugars is a vital part of living with diabetes. It can help you work out when you need to take more medication, when you need to eat something or for when you want to get up and move around more.

Routine checks can help you know when you might be starting to go too low or too high . Its a way of getting to know your body and how it works. It can help you and your healthcare team spot patterns too. Do you write your results down? You might find that helpful.

But importantly, it will help you stay healthy and prevent serious diabetes complications now and in the future. By complications, we mean serious problems in places like your feet and your eyes. This happens because too much sugar in the blood damages your blood vessels, making it harder for blood to flow around your body. This can lead to very serious problems like sight loss and needing an amputation.

The higher your blood sugar levels are and the longer theyre high for, the more at risk you are.

Follow Your Diabetes Meal Plan

Choose fruits and vegetables, beans, whole grains, chicken or turkey without the skin, fish, lean meats, and nonfat or low-fat milk and cheese. Drink water instead of sugar-sweetened beverages. Choose foods that are lower in calories, saturated fat, trans fat, sugar, and salt. Learn more about eating, diet, and nutrition with diabetes.

10 Best Glucose Meter With Cheapest Strips

There are different devices you can use to measure your blood sugar, which work by checking the levels of glucose, or sugar, in your bloodstream. Blood sugar meters or glucometers take a drop of blood to measure your blood sugar at one particular momentwell get to the specifics on how it works in a minute. Continuous glucose meters or CGMs, use a sensor inserted under the skin with a tiny needle to measure blood sugar every few minutes. They sync up to an app, watch, or receiver that stores information about your readings. Then the patient can review their blood sugar data on their device or keep a detailed written log.

CGMs are worn continuously to give you feedback about your blood sugar 24/7 through a sensor placed under the skin of the arm or belly. They can provide very valuable insights and patterns to help you understand how your body best responds to diet and lifestyle factors that impact blood sugar, Palinski-Wade explains. People who wear CGMs still need to use a blood sugar meter once a day to make sure their CGM readings are accurate, says the CDC.

How To Track Blood Sugar Levels

Blood sugar vacillates throughout the day due to many factors, says Megan Wolf, a registered dietitian and diabetes care and education specialist at Cleveland Clinic in Ohio. The preferred way to keep track of it? Whatever works best for you. This may include journaling numbers into a logbook or typing blood sugar readings into an app, says Wolf. A lot of my patients find continuous glucose monitors helpful. Glucometers and continuous glucose monitoring systems store glucose data that can be uploaded to a computer. Then the patient can review their blood sugar data on their device or keep a detailed written log.

How Do I Pick A Glucose Meter

Your doctor will make a recommendation. Check with your health insurance plan to see if it will pay for your BGM, its supplies, or a CGM. If so, your plan may only pay for a certain meter.

Shop around and compare costs. Consider what features are important to you. For example, some meters are made for people who have poor eyesight. If you want to pay a little more money, you can get a BGM that stores the results in its memory. This allows you to compare results from several days at one time.

What Is A Blood Glucose Test

A blood glucose test is a blood test that mainly screens for diabetes by measuring the level of glucose in your blood.

There are two main types of blood glucose tests:

  • Capillary blood glucose test: A healthcare professional collects a drop of blood usually from a fingertip prick. These tests involve a test strip and glucose meter , which show your blood sugar level within seconds.
  • Venous blood glucose test: A phlebotomist collects a sample of blood from a vein . These glucose tests are usually part of a blood panel, such as a basic metabolic panel. The provider will send the samples to a lab. There, a medical laboratory scientist will prepare your samples and perform the test on machines known as analyzers.

Venous blood glucose tests are generally more accurate than capillary blood glucose tests.

Healthcare providers often order fasting blood glucose tests to screen for diabetes. Since eating food affects blood sugar, fasting blood glucose tests show a more accurate picture of your baseline blood sugar.

Theres also at-home blood sugar testing for people who have diabetes. People with Type 1 diabetes especially need to monitor their blood sugar multiple times a day to effectively manage the condition. Continuous glucose monitoring devices are another option for this.

Its important to check blood sugar more frequently if your physician changes your diabetes medications or if youre prescribed other medications, including steroids and certain antibiotics, which can affect blood sugar, notes Wolf. Depending on the drug, it can do wonky things to your blood sugar soon after taking it, sometimes within a few hours. For example, glucocorticoids such as prednisone can cause hyperglycemia via multiple mechanisms, adds Dr. Kohlenberg. His advice: Anytime you start a new medication, review it with your physician to see if this will impact your glucose and diabetes treatment plan.

Best Times To Check Blood Sugar With Type 2 Diabetes

Daily blood sugar checks for type 2 diabetes are individualized and depend on whether you take insulin. If you do, you may need to test before and after meals and before bed, but the frequency could be less often if you take long-acting insulin, the Mayo Clinic notes. If you dont take insulin, you may not need to test your blood sugar, Palinski-Wade says.

It’s typical for your readings to be lower in the morning before you’ve eaten and higher within two hours of having a meal. But in some cases hormone shifts overnight can elevate blood sugar levels in the morning. If you notice your blood sugar is higher upon waking than after eating, your doctor may recommend making changes to your blood sugar medication.

Right Before Lunch Or Dinner

The Most Accurate Method To Test Blood Sugar is NOT A1C Test â Dr. Berg

If youre having trouble getting into your goal range right before your next meal, its very possible that your body isnt getting enough insulin overall. This can take a bit of fine-tuning with your healthcare teams support.

Keep in mind that some meals take longer to digest than others. High-fat meals that are also high in carbohydrates can take many hours to digest, affecting your blood sugar for many hours, too. This means that even though its been 4 hours since your last meal, a high-fat meal could be still impacting your blood sugars 4 hours later because its digesting so slowly.

A high blood sugar level before lunch or dinner could suggest:

  • What you ate or drank at your last meal is still being digested and you didnt get enough insulin with that meal.
  • Your body may need more rapid-acting insulin for your last meal.
  • Your body may need more basal/background insulin during that time of day.
  • Your body may need some extra help from a non-insulin diabetes medication.

A low blood sugar level before your next meal could suggest:

  • Your body may need less basal/background insulin during that time of day.
  • If you also engaged in physical activity after your last meal, you may need a reduced meal dose.

Talk to your healthcare team about making any adjustments to your diabetes regimen to help you achieve your blood sugar goals.

Check Your Blood Glucose Levels

For many people with diabetes, checking their blood glucose level each day is an important way to manage their diabetes. Monitoring your blood glucose level is most important if you take insulin. The results of blood glucose monitoring can help you make decisions about food, physical activity, and medicines.

The most common way to check your blood glucose level at home is with a blood glucose meter. You get a drop of blood by pricking the side of your fingertip with a lancet. Then you apply the blood to a test strip. The meter will show you how much glucose is in your blood at the moment.

Ask your health care team how often you should check your blood glucose levels. Make sure to keep a record of your blood glucose self-checks. You can print copies of this glucose self-check chart. Take these records with you when you visit your health care team.

Testing Too Soon After Eating

Knowing when to test and why that information is useful can help you better control your diabetes. “Often, people will test blood sugar half an hour or an hour after they eat,” says Uelmen, but this is sooner than experts recommend.

Testing too soon after you’ve had a meal or a snack will give you results that are probably too high. The solution for better diabetes control: Test fasting blood sugar, and test every time before you eat. Wait two hours after eating to get the best reading.

Before And After Exercise

This is crucial, because exercising with a low or even in-range blood sugar level can be dangerous, depending on the length and intensity of the exercise you plan to do.

Make sure to work with your doctor to determine an appropriate pre-exercise blood sugar level, but people usually like to have their levels sit a little higher than normal before starting any vigorous cardiovascular exercise to prevent severe hypoglycemia.

On the other hand, some peoples blood sugars tend to rise during exercise, especially if they are doing weightlifting or types of exercise that spike adrenaline levels in the body. Its important to make sure your blood sugar is at an appropriate level in case it will rise during your workout.

You also dont want your blood sugar to be too high before exercise, either. The Mayo Clinic actually advises against people with diabetes exercising if their starting blood sugar is above 250 mg/dL.

This is due to the fact that if a body is exercising without enough insulin in the bloodstream, the liver and kidneys will inadvertently release more sugar into the body, increasing your number even more and putting you at risk for dehydration, ketones, and even increased risk of spiraling into diabetic ketoacidosis .

Always check your blood sugar after exercise as well, as some people require a post-exercise bolus to combat spikes due to temporary pump settings that had decreased their basal rates.
