Smartwatches are a great way to stay connected and in charge, and they're even more useful for people with diabetes. That's because this type of watch can help you with blood glucose monitoring, alert the owner when it is time for insulin shots, and help call emergency services if needed. Best of all? These watches connect to your phone and send all your blood glucose data to your app.

Diabetics dreamt of this for a long time to have quick access to their blood glucose levels. A smartwatch makes it possible to keep track of glucose levels on your wrist.

Many models have built-in Bluetooth so that the wearer can connect them to their phone or tablet for transmitting data via an app. Some diabetics use this feature daily by doing finger pricks and inserting test strips into compatible blood glucose meters or using a continuous glucose meter (CGM).

The watch displays results in real-time. If you're looking for accuracy, some bands come equipped with FDA-approved glucometers, which provide extremely accurate readings. These devices also take advantage of sensors like ECG and SpO₂ (blood oxygen level saturation) along with other useful features including fitness tracking features, sleep tracking, blood pressure, and heart rate monitoring.

Can A Smartwatch Track Blood Glucose Levels?

A smartwatch itself can't track blood glucose levels, but it can work together with a special app to help you monitor blood glucose levels. The device will pair up with your phone and record the data from the watch's sensors when you feel an increase or decrease in your blood glucose levels.

There are rumors that Apple Watch and Fitbit will announce direct blood glucose readings on their devices. However, at this point in time, there is no direct integration to get your glucose levels directly on the watch itself. This year, Apple and Samsung introduced their most recent timepieces, but neither the Galaxy Watch 4 nor Apple Watch 7 can measure sugar levels in the blood.

Which CGM Work With a Smartwatch?

A few market-leading CGMs that pair with most smartwatches include the Dexcom G-Series, Abbott Freestyle Libre, and Medtronic MiniMed 670G. The MiniMed 670G is a hybrid closed loop insulin pump that automatically adjusts basal rates to keep blood sugar levels in check. 

1. Dexcom

The Dexcom G6 mobile software is adaptable to both Apple and Android smartwatches.

The app's main screen offers a wealth of information. It contains your current glucose number and arrow trend, as well as graphs for 1-, 3-, 6- and 24-hour periods.

2. Medtronic

Medtronic is the world's largest insulin pump maker, as well as the only one to manufacture a CGM, called the Guardian Connect.

There is no way to display real-time data from Medtronic on Apple or Android smartwatches yet. You can use the Medtronic mobile app on your phone to view real-time readings.

3. FreeStyle Libre

This system from Abbott Diabetes Care is known as a Flash Glucose Monitor.

To get a reading, users must manually wave their phone or scanner over the tiny circular sensor worn on the arm. There is no clear indication when Abbott will release a direct connection to a smartwatch but there are apps like DiaBox that can help you with a connection.

Which Smartwatch Can Monitor Blood Sugar Levels?

Since 2001 we had the first diabetes watch introduced by GlucoWatch. They tried non-invasive glucose monitoring without the need of penetrating the skin. Unfortunately, they never got FDA approval and had to stop their product in 2007.

Other brands like K'Watch tried to create a non-invasive glucose monitor but none of them really took off.

Today we are grateful that smartwatches can just display the glucose readings on a mainstream watch. Most of the common models compatible with CGM devices include the Apple Watch, Android Wear, Fitbit, and Samsung.

The data from your CGM sensor/transmitter is received by the phone app through Bluetooth. So it's not really the smartwatch monitoring your blood sugar levels but it's more like they act as a conduit to show you what is going on.

The below video wil guide you through other smartwatches for people with diabetes and its essentials.

How Does A Smartwatch Help Diabetic Patients?

A smartwatch is an amazing device that can help diabetics in a number of ways. For example, they can be alerted when their blood sugar reaches high or low levels and take the appropriate action to correct it. In addition, they can track food intake, physical activity, and insulin doses to better manage diabetes.

If you're looking for a way to help keep tabs on your diabetes while still being able to stay connected with the world, then a smartwatch is the perfect device for you! Be sure to do your research before purchasing one so that you get the watch that best suits your needs.

Do Smartwatches Show Accurate Blood Glucose Readings?

Since smartwatches can't do direct blood glucose readings they can't do this accurately. The only way a smartwatch can read your blood glucose is by tracking blood glucose levels via specific apps of your CGM brand like Dexcom.

What to Look for When Buying a Smartwatch

1. Battery Life

One of the most important things to consider when buying a smartwatch is its battery life since many times you'll only get one full charge per night and it's not always reliable for all brands. But if your watch can last up to several days without charging then this will certainly help with diabetes management since you don't have to worry about plugging in every night or two as some watches require right now.

2. Water Resistance

Before buying a smartwatch it's important to check if it is water-resistant or not because you don't want your watch to stop working when you're swimming or taking a shower.

Most smartwatches are waterproof up to a certain depth, but there are some that can be submerged in water without any damage so make sure to double-check before purchasing one.

3. Compatible Devices

Some smartwatches might only work on specific devices, so it's important to check that your phone or tablet is compatible with the watch you're considering.

This isn't as big of an issue as it used to be since most smartwatches now have cross-platform compatibility, but make sure to double-check just in case.

4. Sensor Used

The sensor or device you are using to measure your blood sugar isn't always compatible with all smartwatches. So if you're using a CGM (continuous glucose monitor) then make sure the watch you buy is compatible with that sensor type.

Otherwise, you might be limited to certain brands or models of smartwatches that will work best for your needs.


With the right smartwatch, you can stay connected to your diabetes management while still being able to enjoy a full life. Be sure to do your research before purchasing one so that you get the watch that is most appropriate for your needs and lifestyle.
