Non-invasive blood glucose monitors help people with diabetes check their blood sugar without pricking their fingers several times daily. These are newer, innovative devices that are still advancing in technology. But are they suitable for everyone? Let's look at these devices and see if they might be right for you.
Non-invasive blood glucose monitoring devices allow for easier, more accurate, and more comfortable monitoring of glucose levels.
Different devices are available that use different methods to determine blood glucose levels.
Not all devices are created equally. Some are more accurate than others, and costs may vary widely.
Non-invasive blood glucose monitoring
Non-invasive blood glucose monitoring devices are a breakthrough technology for those suffering from diabetes, allowing for more accurate, convenient, and safe monitoring of glucose levels. Using light sources and sensors, these devices use advanced technology, such as near-infrared spectroscopy or optic reflectance, to measure blood sugar through skin tissue.
The innovative approach reduces the discomfort associated with daily glucose testing while reducing the chance of infection compared to other methods used in traditional monitoring. There are multiple types on the market, and they each work uniquely.
- Continuous glucose monitors. These use a sensor that sticks to the skin on the arm, abdomen, or thigh that uses a small sensor under the skin. It collects glucose levels from the fluid under the skin, tests it every few minutes, and then transmits the information to a monitor. Since this monitors fluid under the skin, it is not a true non-invasive but minimally invasive compared to finger sticks. These monitors can be used with an insulin pump and be connected to your phone.
- Flash glucose monitors. These use special flash technology on a small sensor that you stick on your body. It senses your blood sugar in the fluid inside your skin that leaks out of your blood vessels and then reports it to your phone.
- Optical glucose monitors. These use infrared or optic reflectance technology monitors and sense blood sugar levels. These can be used as a sticker sensor or sometimes by a separate touch sensor that reads the level after touching it.
- Photoacoustic hybrid glucose monitors. These use acoustic energy with optical sensors to excite glucose molecules and convert them into signals to determine the concentration.
- Electromagnetic glucose monitors. These use electromagnetic frequency to sense the high polarization of plasma and measure the glucose in the blood.
The benefits of using these devices
Managing diabetes is a daily challenge for many, requiring monitoring glucose levels and adjusting to lifestyle, diet, or medication. A non-invasive blood glucose monitoring device has revolutionized how those with diabetes manage their condition; rather than drawing multiple drops of blood throughout the day, this innovative device gives users an accurate measurement with just an effortless finger swipe.
Additionally, these devices are easier to use and require fewer supplies compared to invasive methods of tracking glucose currently available. With greater access to readings and trending data throughout the day and night, users can get timely feedback on how diet and exercise impact their daily health results.
Glucose monitors can help to manage glucose levels regularly, have fewer blood sugar emergencies, and decrease the need to stick fingers for monitoring. Certain types of devices may show a graph that can help you manage and monitor your blood sugar more effectively.
The drawbacks of these devices
While non-invasive blood glucose monitoring devices offer great conveniences to individuals with diabetes, their results can be less precise than other methods. Researchers are still developing newer models that increase accuracy, meaning that newer, better models are currently being developed.
Furthering the development of these devices means that you may have to upgrade your device to monitor your levels better. Devices and equipment can be expensive, and insurance does not always cover these costs.
Some other drawbacks include a need for more accuracy due to atmospheric conditions, interference from other electronic objects nearby, and certain levels or peaks in blood glucose that are impossible to detect.
Additionally, the cost of maintaining these devices is high for some consumers since they must be continually serviced and calibrated for accuracy. It's essential for people with diabetes to understand the limitations of invasive monitoring and weigh the pros and cons when deciding how best to track their health.
Who should use one of these devices?
Non-invasive blood glucose monitoring devices can be an excellent tool for anyone to manage their blood sugar better. People who have been diagnosed with diabetes and require blood glucose monitoring to maintain their health, as well as those who think they may be at risk of diabetes or just want to understand their body better, are both highly encouraged to use these devices.
Common reasons people use them:
- Managing type 1 or type 2 diabetes
- Having extreme fluctuations in blood sugar
- Monitoring insulin needs
- Reducing the amount of daily finger sticks
How to choose the right device
Choosing the right non-invasive blood glucose monitoring device can be a challenging process. It is important to consider what you need from this device and consider various factors, including cost, accuracy, user-friendliness, portability, and a power source.
Learn more about the features of each model and determine if they fit your needs. Also, seek advice from healthcare professionals on which particular model is right for you and if any special features benefit you more than others.
When reviewing products, look for something that is budget-friendly, covered by insurance, has FDA approval, and can connect to your smartphone. If you have difficulties figuring out which is right for you, speak with your doctor today for the best options.
