Apple Watch is one of the most popular smartwatches out there and the company has been adding several health-related features to the device. Some of them have been proved to be life-saving for many, especially the electrocardiogram (ECG).

Now, it is being reported that the upcoming version of the device, Apple Watch Series 7 is likely to get another major health-related feature — Blood sugar monitoring. This will be very important for users who are diabetics. As per the report from The Telegraph, an SEC filing hints that Apple will add a glucometer feature to the Apple Watch in 2022.

The feature will come in handy for users who need to get a reading on their blood sugar before each insulin injection since the amount of sugar found in their blood determines the dosage of each shot. Currently, checking the blood sugar level is a bit complex. The user has to draw blood for each test, dab it onto a test strip which is then inserted into a glucometer to obtain a reading.

The current process is a bit painful and costly but if Apple could come up with a solution that can offer blood sugar readings without the need to draw blood or buy new test trips, it could prove to be a major boost to the device’s sales.

The report reveals Apple as the largest customer of Rockley Photonics which has developed next-generation sensors that are expected to be inside devices by next year. Its sensors can read certain signals from a person’s blood by shining infrared light through the skin from the back of a smartwatch.

This also hints that besides glucometer, the company could be looking to add other sensors on the upcoming smartwatch to measure the user’s alcohol level and blood pressure but as of now, nothing has been confirmed by the US-based tech giant.

So far, Apple is offering electrocardiogram (ECG) and blood oxygen level (SpO2) monitoring on its smartwatches. So, it will be great to see support for glucometer on the wearable device in the next edition.
