Understand How Lifestyle Can Impact Glucose Levels
Similarly to getting insight into how certain foods impact energy levels, you can start to understand how your lifestyle choices affect glucose levels too.
If youâve had a hunch that stress leads to blood sugar spikes and crashes, you can test the theory by self-monitoring glucose levels.
And then, you can use the data to optimize your lifestyle habits.
Seeing the impact your habits have will also encourage you to stick to them. You may notice long-term improvements in glucose levels, insulin sensitivity, and weight management with healthier habits.

Monitoring Glucose Reduces Hba1c In Type 1 And 2 Diabetes
You may already be aware that self-monitoring glucose levels is supposed to help. But did you know that continuous glucose monitoring can be even more beneficial than the standard finger-prick method?
One study found that self-checking blood sugar levels using a continuous blood glucose monitor significantly reduced hemoglobin A1c or HbA1c compared to standard glucose testing in the management of those with type 1 diabetes. Researchers have found similar benefits for type 2 diabetes management.
This may be due to 24/7 data on glucose levels allowing you to see what foods your body reacts well to. It also becomes easier for you to connect the dots and learn how to better manage your levels.
CGMs require less attention from the user. They only require minimal scanning every eight hours or less and you can have access to your glucose levels throughout that time. With a glucometer or finger-prick method, you may forget or feel aversive to pricking your finger multiple times a day.
Researchers also describe that continuous glucose monitoring can allow people to measure silent hypo or hyperglycemia .
Regardless of if you are using standard glucose testing at home or a continuous monitor, regular self-monitoring can be beneficial for improving HbA1c and managing diabetes.

When Would I Need A Blood Glucose Test
There are three main reasons why you may need a blood glucose test:
- Your healthcare provider may have ordered routine bloodwork called a basic metabolic panel or a comprehensive metabolic panel , which both include a glucose blood test.
- You may be having symptoms of high blood sugar or low blood sugar, which could indicate diabetes or another condition.
- If you take a long-term medication that affects your blood sugar levels, such as corticosteroids, you may need routine glucose blood tests to monitor your levels.
The most common use of a blood glucose test is to screen for Type 2 diabetes , which is a common condition. Certain people are at risk for developing Type 2 diabetes. If you have risk factors, your provider will likely recommend regular screening no matter your age. The American Diabetes Association recommends regular screening for anyone age 35 or older.
Your provider will also order a blood glucose test if you have symptoms of high blood sugar or low blood sugar .
Symptoms of diabetes and high blood sugar include:
- Feeling very thirsty .
- Intense hunger.
- Anxiousness or irritability.
You need to consume carbohydrates to treat hypoglycemia, such as a banana or apple juice. Severe hypoglycemia can be life-threatening.
What If I Cant Get A Drop Of Blood For A Fingerstick
If you want to get blood from your fingertip, try washing your hands in hot water to get the blood flowing. Then dangle your hand below your heart for a minute. Prick your finger quickly and then put your hand back down below your heart. You might also try slowly squeezing the finger from the base to the tip.

A1c Tests Can Be Affected By Changes In Red Blood Cells Or Hemoglobin
Conditions that change the life span of red blood cells, such as recent blood loss, sickle cell disease, erythropoietin treatment, hemodialysis, or transfusion, can change A1C levels.
A falsely high A1C result can occur in people who are very low in iron for example, those with iron-deficiency anemia. Other causes of false A1C results include kidney failure or liver disease.
If youre of African, Mediterranean, or Southeast Asian descent or have family members with sickle cell anemia or a thalassemia, an A1C test can be unreliable for diagnosing or monitoring diabetes and prediabetes. People in these groups may have a different type of hemoglobin, known as a hemoglobin variant, which can interfere with some A1C tests. Most people with a hemoglobin variant have no symptoms and may not know that they carry this type of hemoglobin. Health care professionals may suspect interferencea falsely high or low resultwhen your A1C and blood glucose test results dont match.
Not all A1C tests are unreliable for people with a hemoglobin variant. People with false results from one type of A1C test may need a different type of A1C test to measure their average blood glucose level. The NGSP provides information for health care professionals about which A1C tests are appropriate to use for specific hemoglobin variants.

Why You Should Check Your Blood Sugar
Blood glucose levels constantly fluctuate as you eat, exercise, and sleep. To get accurate insight into your glucose levels, youâll want to start monitoring them throughout the day.
While HbA1c testing every few months can be necessary, monitoring your levels on a more regular basis can improve your habits and optimize your health. Letâs dive into how checking your blood sugars on a more regular basis does that.

How The Test Is Done
You can buy a testing kit from a pharmacy without a prescription. Your provider can help you choose the right kit, set up the meter, and teach you how to use it.
Most kits have:
- Small needles that fit into a spring-loaded plastic device
- A logbook for recording your numbers that can be downloaded and viewed at home or at your providers office
To do the test, prick your finger with the needle and place a drop of blood on a special strip. This strip measures how much glucose is in your blood. Some monitors use blood from areas of the body other than the fingers, reducing discomfort. The meter shows your blood sugar results as a number on a digital display. If your vision is poor, talking glucose meters are available so that you dont have to read the numbers.
Be aware that no meter or strip is accurate 100% of the time. If your blood sugar value is unexpectedly high or low, measure again with a new strip. Do not use strips if the container has been left open or if the strip has gotten wet.

Ways To Test Your Blood Sugar
Traditional home glucose monitoring
You prick your finger with a small, sharp needle called a lancet, put a drop of blood on a test strip, and then place the strip into a meter that displays your blood sugar levels. Record the test results so you can share them with your doctor. Based on your results, the two of you may adjust your diet, exercise, or medication.
Meters vary in features, portability, speed, size, cost, and readability . Devices deliver results in less than 15 seconds and store this information for future use.
Some meters also calculate an average blood sugar level over a span of time. Some also feature software kits that take information from the meter and display graphs and charts of your past test results. Blood sugar meters and strips are available at your local pharmacy.
Meters that test other parts of your body
Some devices let you test your upper arm, forearm, base of the thumb, and thigh.
These results may differ from the blood sugar levels gotten from a fingertip stick. Levels in the fingertips show changes more quickly. This is especially true when your sugar is changing fast, like after a meal or after exercise.
If you have symptoms of low blood sugar, donât rely on test results from other parts of your body.
Continuous glucose monitoring system
Youâll still need to check your levels throughout the day continuous glucose monitoring doesnât replace that. It gives your doctor more information about trends that self-checking might not show.
Keep Track Of Your Testing Strips
Make sure your strips arent expired. Out-of-date strips arent guaranteed to return true results. Old strips and inaccurate results may affect your daily log of blood glucose numbers, and your doctor may think theres a problem when there really isnt.
Also, keep the strips out of sunlight and away from moisture. Its best to keep them at room temperature or cooler, but not freezing.

Who Are They Useful For
CGMs can help people with diabetes monitor and maintain their blood glucose levels. While they do not involve finger pricking, they may be useful to calibrate the device.
Earlobe, breath, and other noninvasive devices may be beneficial for monitoring blood glucose levels, especially in children with the same condition and those who have cystic fibrosis. However, they are not FDA-approved, while some may need to undergo further testing to determine their safety and accuracy.

What Does A High Blood Glucose Level Mean
If your fasting blood glucose level is 100 to 125 mg/dL , it usually means you have prediabetes. People with prediabetes have up to a 50% chance of developing Type 2 diabetes over the next five to 10 years. But you can take steps to prevent Type 2 diabetes from developing.
If your fasting blood glucose level is 126 mg/dl or higher on more than one testing occasion, it usually means you have diabetes.
In either of these cases, your provider will likely order a glycated hemoglobin test before diagnosing you with prediabetes or diabetes. An A1c shows your average blood sugar over a few months.
There are a few different types of diabetes. The most common forms are:
- Type 2 diabetes : T2D happens when your pancreas doesnt make enough insulin or your body doesnt use insulin well , resulting in high blood glucose levels. This is the most common type of diabetes.
- Type 1 diabetes : T1D is an autoimmune disease in which your immune system attacks the insulin-producing cells in your pancreas for unknown reasons. Your pancreas can no longer produce insulin. At diagnosis, people with Type 1 diabetes usually have very high blood glucose .
- Gestational diabetes: This condition can develop in pregnant people usually appearing during the middle of pregnancy, between 24 and 28 weeks. The high blood sugar goes away once the pregnancy is over. Pregnant people have screenings for gestational diabetes with a glucose challenge test and/or glucose tolerance test.
What Can Affect My Results
They may not be accurate if you have anemia or gout. If itâs hot, humid, or youâre at a high altitude, that can interfere with the results, too. So can vitamin C.
If you consistently see results that arenât expected, recalibrate your meter and check the strips.
The chart below shows you the ideal blood sugar ranges for most adults except for pregnant women. Your ideal range may be different from another persons and will change throughout the day, so check with your doctor for your targets.

A1c Results And What The Numbers Mean
| Diagnosis* | |
|---|---|
| Diabetes | 6.5 percent or above |
When using the A1C test for diagnosis, your doctor will send your blood sample taken from a vein to a lab that uses an NGSP-certified method. The NGSP, formerly called the National Glycohemoglobin Standardization Program, certifies that makers of A1C tests provide results that are consistent and comparable with those used in the Diabetes Control and Complications Trial.
Blood samples analyzed in a doctors office or clinic, known as point-of-care tests, should not be used for diagnosis.
The A1C test should not be used to diagnose type 1 diabetes, gestational diabetes, or cystic fibrosis-related diabetes. The A1C test may give false results in people with certain conditions.
Having prediabetes is a risk factor for developing type 2 diabetes. Within the prediabetes A1C range of 5.7 to 6.4 percent, the higher the A1C, the greater the risk of diabetes.
Can You Check Your Blood Sugar At Home Without A Meter
The advances in health technology have made it much easier for people to get real-time insights into their blood glucose, or blood sugar, levels. But testing and monitoring your glucose levels itself isn’t new. The first diagnostic test for diabetes was created as far back as 1841. It analyzed glucose levels by analyzing urine using acid hydrolysis, a test that breaks down larger molecules such as glucose into smaller ones.
Over the following centuries, scientists refined this urine analysis method further by using different compounds. But it wasnât until the 1970s that glucose blood tests such as the hemoglobin A1c, or HbA1c, became available.
Eventually, at-home finger-prick tests became available for use by the general public. Nowadays, technology has made it even easier to get 24/7 glucose level analysis without needing to prick fingers every time. You can now use tools like the continuous glucose monitor to track glucose in real-time.
Read on to learn how glucose testing and self-monitoring has made it easy for people to maintain normal blood glucose levels.
