How Often To Check Blood Sugar

Right Before Lunch Or Dinner

How Often Should We Check Blood Sugar – Type 2 Diabetes

Checking your blood sugar before your next meal can tell you two things:

  • How well your body and/or medication dosages handled your last meal
  • How well your body and/or medication dosages handled your blood sugar in the last few hours without food being digested.

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.

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

  • What you ate or drank at your last meal was more than your body could handle on your current diabetes management regimen.
  • Your body may need some extra help from a diabetes medication.
  • Your current diabetes medications may need a change in dosage.
  • Your current diabetes medication may not be the right fit for you.
  • Its time to try a different type of diabetes medication.
  • Your overall insulin production or insulin resistance level has changed and your body needs more support from a new or current medication.

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

  • Youre getting too much of a certain diabetes medication .
  • Your insulin sensitivity or insulin production has improved, which means your medication dosages need to be adjusted by your healthcare team.

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

What Are Blood Sugar Targets

A blood sugar target is the range you try to reach as much as possible. These are typical targets:

  • Before a meal: 80 to 130 mg/dL.
  • Two hours after the start of a meal: Less than 180 mg/dL.

Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.

How Many Times Do You Really Check Your Blood Sugars At The Early Stages Of Diabetes

You dont really have to check too many times. If your blood sugars are not very uncontrolledMeaning your A1c is below 7%, you can check it once a day in the mornings, just to keep an eye on your blood sugars overall. As we mentioned occasionally you can check it after meals to see where your blood sugars are. You can do that occasionally after meals. Lets say you think that you had too much carbs, and you want to check. This will help you understand how food affects you and so forth. For example,if your overall well controlled and youre waking up with you know say 100 Or 110 and then occasionally you check after meals and you never go more than 160 170 after meals then youre pretty well controlled.

Overcoming Barriers To Blood Sugar Monitoring

Some people find it difficult to incorporate blood sugar monitoring into their daily or weekly routines. There are lots of reasons for this:

  • If blood sugar readings are consistently high, it can be upsetting
  • Monitoring seems pointless
  • Finger pricks to get a drop of blood are uncomfortable
  • Monitoring is inconvenient

Blood sugar monitoring is an important tool that can help you manage your diabetes effectively and prevent or delay complications.

Get The Best Use Out Of Your Strips

How to check your blood sugar at home and how often to do it

There are many times you could check. How often should you? “Everyone wants black-and-white answers,” says Mary M. Austin, R.D., CDE. “It’s not how often you do it it’s what you do with the information.”

Endocrinologist Tom Elasy says people and health care providers need to distinguish between the intensification stages of diabetes — when diabetes is newly diagnosed or when you and your provider make changes in your treatment plan — and the maintenance phase — when you are reaching your glucose goals and things are in a pretty steady state.

How to Make the Best Use of Your Strips: Medicare, for people who have Part B, covers 100 test strips every three months for a PWD who doesn’t take insulin.

For someone newly diagnosed with type 2, how can you make the best use of your strips? According to Elasy, use more strips when you’re diagnosed and learning about the impact of what you eat, your physical activity, and medications on your glucose levels. Once you get a sense of your fluctuating glucose levels, testing doesn’t need to happen as often. As type 2 diabetes progresses over time, renewed, more frequent testing often is necessary.

People who do not take any glucose-lowering medications might want to check at least once or twice a week just to keep track. It is recommended that you do monitor and use your allotted strips wisely. Monitoring can have a powerful, positive effect on how you subsequently eat or the likelihood that you’ll take a walk, Elasy notes.

Monitoring Your Blood Sugar

Regular blood sugar monitoring is the most important thing you can do to manage type 1 or type 2 diabetes. Youll be able to see what makes your numbers go up or down, such as eating different foods, taking your medicine, or being physically active. With this information, you can work with your health care team to make decisions about your best diabetes care plan. 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.

How Do Carbs Affect Blood Sugar

Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have and stay in your target blood sugar range depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels. Make sure to talk to your health care team about the best carb goals for you.

Why Monitor Your Blood Sugar Levels

Whether you have type 1 or type 2 diabetes, monitoring blood sugar is an important part of your management regimen. Blood sugar monitoring provides a lot of useful information, as it can help you:

  • Judge how well youre reaching your blood sugar targets
  • Know how diet and exercise affect your blood sugar levels
  • Understand how other factors affect your blood sugar
  • Monitor the effect of your diabetes medications on your blood sugar levels
  • Identify highs and lows

Don’t Forget These Important Times To Test

How Often Should I Check My Blood Sugar Level?

You should also test your blood sugar if you:

Are sick or have an infection. Illness can send blood sugar levels up. Do a check every two to four hours. If it’s:

Over 250 mg/dl, check your urine for ketones if ketones are present in more than trace amounts, call your doctor.

* Over 250 mg/dl for more than six hours, call your doctor.

* Over 350 mg/dl even once, call your doctor.

Start a new blood glucose-lowering medication or change the dose of one. A prescription or over-the-counter medicine for a condition other than diabetes may affect blood sugar levels. Steroids are one example.

Are under a lot of stress. Emotional stress may lead to higher blood sugar numbers. Exercise — even just a walk around the block — can help reduce stress and glucose levels.

Feel as though your blood sugar level is too low. If your meter confirms it with a number of 70 mg/dl or less, eat 15-20 grams of pure glucose or drink 1/2 cup fruit juice or regular soda. Wait 15 minutes and check again to make sure it has come back into the normal range.

Meters that test other parts of your body

Blood can be taken from any part of the body however, the results are most accurate when taken from the fingers.

Continuous glucose monitors are another option. A small sensor with a needle is attached to the skin. The sensor reads the blood glucose levels every few minutes. The information is relayed back to a data receiver. The data receiver can be carried in a pocket or purse. Alarms can be set to go off if glucose reaches certain levels. Many factors can affect insulin levels. CGMs relay more accurate results than finger pricks secondary to continuous glucose monitoring around the clock.
