Comparison To Other Devices
The FreeStyle Libre is referred to as a flash glucose monitoring system. Unlike other CGMs, like the Medtronic Guardian 3 and Dexcom G6, the FreeStyle Libre checks glucose levels every minute rather than every five minutes. It can also be worn for 14 days as opposed to seven days for the Medtronic Guardian 3 or 10 days for the Dexcom G6.
The FreeStyle Libre system does not require fingerprick calibrations. And, because there is no transmitter, the system costs less than other CGMs.
Whereas other CGM sensors can be placed on the belly and buttocks, the FreeStyle Libre is only approved for use on the back of the arm. If placed in other areas, the sensor may not work properly.
A newer CGM called the Eversense system offers continuous 90-day glucose monitoring. But sales of the device were halted in 2020 due in part to the COVID-19 pandemic but also to the fact that the device has to be implanted by a doctor.
Diabetes Increases The Risk Of Health Complications
Diabetes has the potential to cause numerous debilitating health complications. Most often, complications are the result of an unmanaged or poorly managed diabetes. However, people with appropriate diabetes management are also at risk of developing complications.
Half of the 463 million adults living with diabetes today are unaware that they have the condition, and are therefore at high risk of developing serious diabetes-related complications.
Globally, 11.3% of deaths are due to diabetes. Almost half of these deaths are in people under 60 years of age.
Why Do We Need To Measure Our Blood Sugar Levels
We measure our blood sugar levels in order to know what the level of glucose is in our body. This is important because it tells us how health we are and isnt a bad sign. We get this information by doing finger pricks to draw blood. The problem is that these fingerpricks can be painful and can take time to heal depending on the size of the prick. It also limits mobility while recovering from the injury.

Calibrate The Glucose Meter:
Next, you will have to calibrate the glucose meter. So for this, start by inserting a code key into the strip slot. After that, you will need to check that the number appearing on the screen is as same as the number on the test strips. Also, you should be aware of the fact that you should calibrate your glucose meter every time you open a new box of test strips.
Why Test Blood Sugar Levels
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.

When Should I Measure My Blood Glucose
Throughout the rest of your pregnancy, you will need to measure your blood glucose levels at various points through the day, to check that they are within the limits you have been given at each of those times:
When you get up You need to measure your blood glucose levels each morning when you get up, before you have anything to eat or drink. This blood glucose level is called your fasting blood glucose level because you will have an empty stomach. You must not have eaten or drunk anything apart from water overnight, for at least eight hours.
Your team should have discussed this with you and agreed the ideal morning blood glucose level for you to aim for.
Before or after every meal You will probably be asked to measure your blood glucose level around the time of a meal. Some services measure before eating while others measure one or two hours after a meal .
Again, you will have discussed and agreed an ideal blood glucose level after meals with your diabetes team. These levels will be higher than your fasting blood glucose levels, as you will just have eaten.
If you are taking insulin to help to control your blood glucose levels, you may need to do a separate test before you go to bed, or even during the night, although this is unusual.
“When we did go out for a special meal or two, and I’d have a little bit of cheesecake or something, it really affected my sugar levels. But that would’ve been just twice in the whole pregnancy.” Gemma, mum of one
When To Talk With A Pro
Testing your blood sugar is crucial to diabetes management. Using a meter or continuous glucose monitoring can provide accurate results. But you might seek a pain-free method to check blood sugar.
Talk with your doctor or a certified diabetes educator. You might be a candidate for a glucose monitoring device that involves fewer finger pricks or no finger pricks.
Additionally, making a few adjustments in the way you collect your blood sample might reduce the level of pain and discomfort.

Measuring Blood Sugar Without Pricking Your Finger
Diabetic patients should be able to monitor blood sugar levels without having to prick their fingers. The medical technology students are trying to find a solution.
The blood sugar level in diabetic patients must be regulated to avoid serious illness. Frequent measurements are important, but the patients still need to insert a needle through the skin to get correct values and they do not receive continuous blood glucose levels.
Cool that it is possible to produce such a device by 3D modelling.Sindre
Five medical technology students at the electrical engineering bachelor programme at Oslo Metropolitan University are trying out a method that can continuously measure blood sugar levels without pricking.
This can be done by transmitting vibrations through the skin by ultrasound to the so-called interstitial fluid between the cells, see a preliminary demonstration in the picture at the top.
What Top Groups Recommend
Heres what some organizations say about self-monitoring of blood glucose:
- In its 2017 Standards of Care, the American Diabetes Association notes the evidence is insufficient regarding when to prescribe SMBG and how often testing is needed for patients who do not use intensive insulin regimens The ADA goes on to say that a key consideration is that performing SMBG alone does not lower blood glucose levels. To be useful, the information must be integrated into clinical and self-management plans.
- In a recommendation updated in February, the Society of General Internal Medicine advises against daily home finger glucose testing in type 2 diabetes patients who arent using insulin. Such testing doesnt benefit patients who arent on insulin or sulfonylureas, the group says.
- Since 2013, The Endocrine Society has recommended against multiple daily self-glucose monitoring by adults with stable type 2 diabetes who are not being treated with anything that could cause hypoglycemia.

How Does A Flash Glucose Monitor And Cgm Work
Flash glucose monitors and continuous glucose monitors let you check your blood sugar levels without you having to prick your fingers.
You wear a small sensor on your body day and night that reads your blood sugar levels so you can see the information on your mobile, or other device. If someone helps you look after your diabetes, their mobile can be linked up too.
With a CGM and the latest flash glucose monitor , you can also set an alarm to sound if your blood sugar levels go too low or too high.
This can also be set up to sound on someone elses mobile, for example, a parent or carers.
One of the other main benefits of a flash glucose monitor and CGM is being able to review what your blood sugar levels do every minute of the day and night. With the charts and graphs, you can start to see and understand how food, activity, and other things affect your blood sugar levels.
“It’s a real mental health break knowing what your blood sugar levels are doing at any one time.” Matt
Can The Apple Watch Monitor Blood Sugar
The new Apple Watch can run an app that measures blood glucose levels. DexCom created the app, which can track and show glucose levels in the form of a graph. The company also made a sensor that fits into the watch’s case to collect data on behalf of the app. The Dexcom app is currently available for download from the App Store it’s free but requires a monthly subscription fee after the first month.
How does the Apple Watch work with diabetes? The Apple Watch works with any iPhone containing the necessary software. To use the device with Dexcom sensors, your phone must be running iOS 8.0 or later. The Apple Watch will sync with your iPhone over Wi-Fi unless you disable this feature. It can then communicate with the Dexcom sensor attached to your skin by Bluetooth.
You can view your blood glucose levels at any time using the touch screen on the Apple Watch. You will need to connect the watch to a phone with an Internet connection, however, because the app that does this is only available via the App Store.
Does the Apple Watch help people with diabetes manage their condition? The Apple Watch is designed to help people with diabetes better manage their conditions by providing information about their blood glucose levels and offering guidance on what actions may improve them.

Blood Sugar Monitors Without Finger Pricks
The increased incidence of sedentary lifestyles have brought about a rise in the number of lifestyle diseases. The most common among them is Type 2 diabetes. One of the key factors in managing this disease is to keep a constant tab on ones blood glucose levels. This involves monitoring of blood sugar levels several times a day and keeping a record of it.
Most devices used to measure blood sugar levels require numerous finger pricks in a day. This is either to obtain the blood sample or calibrate the device. Since most individuals are clueless about how to check diabetes without blood tests, this constant finger pricking turns out to be a discouraging factor. The pain associated with it acts like a deterrent in maintaining proper records of blood sugar levels. In such a scenario, the emergence of blood sugar testing systems, which do not require finger pricking, turns out to be a welcome alternative. Non-invasive methods of blood sugar testing makes managing diabetes a comparatively pain-free experience.

Not exactly. The most widely known method of checking blood sugar is using the finger-prick method with a glucometer. If youâre not familiar, this method involves pricking your finger using a lancet.
Once pricked, you can place the drop of blood on a strip. The strip is then inserted into a meter that measures the amount of glucose attached to your blood cells.
Weâve already alluded to this, but â thanks to modern technology â you donât have to prick your finger every time you want to check your glucose levels.
Fda Approves First Blood Sugar Monitor Without Finger Prick
U.S. regulators have approved the first continuous blood sugar monitor for diabetics that doesn’t need backup finger prick tests. Current models require users to test a drop of blood twice daily to calibrate, or adjust, the monitor. Most of the 30 million Americans with diabetes use standard glucose meters, which require multiple finger pricks each day and only show current sugar level. “The pros of the new device are that it is a 10-day wear, it is low-profile and that no calibration needed,” said Carol Levy, MD, CDE, associate professor of endocrinology, diabetes and bone disease, obstetrics, gynecology and reproductive science at the Icahn School of Medicine at Mount Sinai. “The cons of the device are that is has no alerts for either high or low BG levels for patients with hypo-unawareness, which could be a challenge. It also requires a separate receiver to view data — other systems on the market can have data viewed on the smart phone, she added.

Tips For Checking Your Blood Sugar With Less Pain
Fingertips have more nerve endings, so this part of the finger tends to be the most sensitive.
If you use a finger prick to check your blood sugar level, a few techniques can make the process less painful whether youre using a glucometer or a continuous glucose monitor.
Blood sugar testing is crucial to diabetes management because high or low blood sugar can cause severe complications. If too much blood sugar accumulates in your bloodstream, you can experience major complications such as:
- difficulty speaking
Blood sugar can fluctuate throughout the day especially after meals, after exercising, and during stressful events. So its important to carefully monitor your blood sugar and keep it within a healthy range.
A blood sugar level less than 140 milligrams per deciliter , but greater than 70 mg/dL is typically considered in the target range.
You should check your blood sugar regularly, even if you arent experiencing symptoms of a high or low glucose level. Some people with high and low blood sugar dont have any symptoms.
Talking With Your Doctor About Your Target Blood Sugar Levels
In general, your target will be 80130 mg/dl before a meal and less than 180 mg/dl after a meal.
In addition to daily monitoring, your doctor will measure your HbA1c at regular intervals. This blood test helps your doctor understand if your treatment plan is working to control your blood sugar levels. An ideal HBA1c level should not exceed 7%.
Carrying out this test will also help you and your doctor determine the next step to take in your diabetes management plan.
