What Are The Freestyle Libre Arm Patch And App
The Freestyle Libre arm patch is a 5cm radius flat device that those affected by type 1 diabetes attach to their upper arm and use to measure their glucose levels. It is an improvement compared to the old way of glucose levels measurements in which a blood sample is drawn from the fingertip and placed on a test strip 35 times per day. It is however also very different from a more advanced continuous glucose measurement device , which as the word says, gives you continuous insight into glucose levels and can therefore be used for a closed-loop. The Freestyle Libre system provides information about recent glucose levels only at the moments you scan your sensor with your phone as shown in the picture below.
The fully continuously measuring glucose measurement devices are expensive and in most countries, they are therefore only provided to patients that satisfy stringent criteria such as:
- Very bad regulated glucose levels with high Hba1c .
- Dangerous incidents during hypoglycemia .
- Low aged children who for whatever reason might benefit from it.
The setup of a system that looks like this has profound impacts on the lives of people with diabetes type 1. As Marry Patton describes in her article published in the Australian diabetes journal One year of DIY looping after 38 years of type 1 diabetes:
Do I Need To Figure Out How To Use A Cgm Device On My Own
It takes time and patience to understand how a CGM device works. But you dont have to do it alone. Your provider will need to prescribe a CGM device .
Once you have a CGM, a qualified professional helps you learn how to use it safely. Your provider may recommend taking a diabetes education class or speaking one-on-one with a certified diabetes educator .
What Is A Biosensor
According to the Oxford Dictionary: A biosensor is a device that uses a living organism or biological molecules, especially enzymes or antibodies, to detect the presence of chemicals.
Biosensors can be part of a single-use test kit or a long-term monitoring device. Each system uses a combination of elements for the rapid detection and measurement of specific molecules.
There are a wide variety of applications for biosensors, and they are used most commonly in healthcare settings. Because of their ability to be highly selective, sensitive, and relatively easy to use, biosensors can rapidly recognize and measure key biometrics in bodily fluids to aid in health monitoring. Examples of commercially available biosensors include:
- At-home pregnancy tests
- Cholesterol meters

Choosing The Right Blood Glucose Meter
For most people, a blood glucose meter is just a part of life. Thats why getting it right matters.
The two main types are standard blood glucose meters that use a drop of blood to check what your levels are at that moment and continuous glucose monitors that check your blood glucose regularly day or nightpick the one that works best for you and your lifestyle.
Of these two options, there are more choices than ever, from basic designs to more advanced models that have all the bells and whistles. And fancier isnt necessarily better. Here are some things to consider:
- Ease of useSome meters are made for simpler operation, whether its larger buttons, illuminated screens or audio capabilities.
- Cost and insurance coverageMeters vary in price, and some insurers limit coverage to specific models. Start by checking with your provider to find out what theyll cover.
- Information retrievalConsider how the meter retrieves your information and whether you can download the data to a computer or mobile device to make it easier to share with your diabetes care team.
- FlexibilityIf youre using a blood glucose meter and are tired of finger pricks, theres an alternative site monitor that lets you draw blood samples from your arm, thigh, or the palm of your hand.
What Causes Blood Sugar To Be High
Many things can cause high blood sugar , including being sick, being stressed, eating more than planned, and not giving yourself enough insulin. Over time, high blood sugar can lead to long-term, serious health problems. Symptoms of high blood sugar include:
- Feeling very tired.
- Having blurry vision.
- Needing to urinate more often.
If you get sick, your blood sugar can be hard to manage. You may not be able to eat or drink as much as usual, which can affect blood sugar levels. If youre ill and your blood sugar is 240 mg/dL or above, use an over-the-counter ketone test kit to check your urine for ketones and call your doctor if your ketones are high. High ketones can be an early sign of diabetic ketoacidosis, which is a medical emergency and needs to be treated immediately.

How Does A Glucose Sensor Work
Glucose testing tools like glucose meter test strips and wearable sensors are glucose biosensors. These compact devices are comprised of several crucial components for the detection and measurement of glucose.
The National Center for Biotechnology Information features an exhaustive explanation of the parts of a biosensor.
For a glucose biosensor, the following components are used:
- Analyte: A substance with chemical constituents that are being identified and measured. In this instance, glucose is the analyte that the biosensor is designed to detect.
- Bioreceptor: This is a molecule that specifically recognizes the analyte. For the detection of glucose, specific enzymes are used, which are proteins that facilitate a chemical reaction. For example, the test strip for a blood glucose test contains the enzyme that interacts with the analyte in the drop of blood.
- Transducer: This part of the biosensor converts one form of energy into another. Specifically, it converts the recognition of the bioreceptor into a measurable signal. Most modern-day glucose meters and continuous glucose monitors measure electrical signals, although earlier generations of glucose meters used a colorimetric process that was measured optically.
- Electronics and display: These components process the transduced signal and prepare it for display. The processed signals are then quantified and shown on either the glucose meters display or the receiver for a continuous glucose monitor .
How Do Continuous Glucose Monitoring Devices Work
You can choose among a handful of CGM devices available today. Each works pretty much the same way. The main differences are in a devices look, feel and features.
In general, heres how CGM works:

If its your first time opening the app, then you may need to set up an account. Once youve done that, hold your phone or device up to the sensor and you should feel it buzz twice. The sensor has been scanned and the app requires 60 minutes to calibrate so youll need to wait that long and then you can use it.
What Is Diabetes Type 1
Type 1 diabetes is an autoimmune disease in which the insulin-producing cells of the pancreas are destroyed by the immune system. Insulin is a hormone required for all cells in the body to use glucose as energy after it has been absorbed from food in the gastrointestinal tract into the bloodstream. Insulin thereby helps to regulate glucose levels in the bloodstream. Without insulin, type 1 diabetes will lead to high glucose levels which can range from fatigue to dehydration. In the worst-case scenario, the absence of insulin leads to a dangerous decrease in blood acidity with coma and death as a consequence. The administration of insulin is the only way to prevent this. It is administered into fat tissue, or in the case of hospital admission, it can also be administered intravenously .

Special Requirements Needed To Use A Cgm
Twice a day, you may need to check the CGM itself. Youll test a drop of blood on a standard glucose meter. The glucose reading should be similar on both devices.
Youll also need to replace the CGM sensor every 3 to 7 days, depending on the model.
For safety its important to take action when a CGM alarm sounds about high or low blood glucose. You should follow your treatment plan to bring your glucose into the target range, or get help.

Sensor Glucose Versus Blood Glucose: Why Sensor Glucose Does Not Equal Blood Glucose
Your blood glucose meter measures glucose levels in your blood. The glucose sensor measures glucose in the fluid surrounding your cells. Glucose travels between these two areas. Most of the time glucose travels from your blood vessels into the fluid. So, your blood glucose meter readings and sensor glucose readings lets call them BGs and SGs will be close but will rarely match exactly. This difference is normal and should be expected.
Its helpful to think about it like a rollercoaster where the front car is the BG and the car in the back is the SG.
When on the rise, the BG value is greater than the SG that follows behind it. But when moving down the tracks, the BG in front is now less than the SG value.
When glucose levels are rising or falling quickly, you should expect to see an even larger difference between your BG meter reading and the sensor glucose readings.

Difference Between A Flash Glucose Monitor And A Cgm
With a CGM your latest sugar levels show up on device or mobile automatically, transmitted by Bluetooth. With a flash glucose monitor, its only when you wave your device over your sensor that you get your blood sugar readings.
Some people prefer to use Flash over CGM. Reasons can include not liking the alarms. But unlike Flash, a CGM can talk to an insulin pump, if you want to use a closed loop system.
Your diabetes healthcare team should be able to support you to make the decision on which device will be best for you.
What Is Diabetic Ketoacidosis
If you think you may have low blood sugar, check it even if you dont have symptoms.
When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:
- Fast, deep breathing.
- Nausea and vomiting.
If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, . DKA requires treatment in a hospital.
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.

Special Features Of A Cgm
CGMs are always on and recording glucose levelswhether youre showering, working, exercising, or sleeping. Many CGMs have special features that work with information from your glucose readings:
- An alarm can sound when your glucose level goes too low or too high.
- You can note your meals, physical activity, and medicines in a CGM device, too, alongside your glucose levels.
- You can download data to a computer or smart device to more easily see your glucose trends.
Some models can send information right away to a second persons smartphoneperhaps a parent, partner, or caregiver. For example, if a childs glucose drops dangerously low overnight, the CGM could be set to wake a parent in the next room.
Currently, one CGM model is approved for treatment decisions, the Dexcom G5 Mobile. That means you can make changes to your diabetes care plan based on CGM results alone. With other models, you must first confirm a CGM reading with a finger-stick blood glucose test before you take insulin or treat hypoglycemia.
