You can check your blood sugar levels with your phone using a continuous glucose monitor (CGM). These devices are worn on your skin and continuously measure your blood sugar levels, sending the readings to your smartphone via Bluetooth. Some CGMs are available by prescription, while others are over-the-counter.
To use a CGM, you'll need to:
- Insert the sensor into your skin, usually on your arm or abdomen.
- Download and set up the app on your phone that's compatible with the CGM.
- Calibrate the sensor with a finger-prick blood sugar test.
Once you've set up your CGM, you can check your blood sugar levels at any time on your phone. The app will display your current blood sugar level, as well as your historical data. Some apps can also send you alerts if your blood sugar levels go too high or too low.
Another option is using a blood sugar meter that connects to your phone via Bluetooth. You'll need to use a lancet to prick your finger and get a blood sample, which you'll then place on a test strip. The meter will transmit the reading to your phone, where you can track your blood sugar levels.
Note: It's important to talk to your doctor or healthcare provider before using any CGM or blood sugar meter. They can advise you on the best option for your individual needs and help you understand how to use the device safely.
