What do people with diabetes wear on their arm?

My friend, who has diabetes, recently started wearing a small patch or device on his arm. I'm wondering what it is and what its purpose is for people with diabetes.

It is a small, round plastic patch called a Continuous Glucose Monitor (CGM). It stays on the arm and helps them check their sugar levels on their phone without pricking their fingers every time. It is very helpful and painless.

That's a CGM sensor, usually FreeStyle Libre in India. It sticks to the back of your upper arm and tracks glucose levels 24/7. You just scan it with your phone and get the reading instantly. It's super convenient for active people.

That's a continuous sugar sensor. It is great because you can see your sugar levels drop in real-time when you go for a brisk 30-minute walk after meals. If your doctor approves, using this device can really help you tailor your daily exercise and diet perfectly.

It is a continuous glucose sensor. If you are diabetic, it helps you manage your HbA1c levels efficiently by showing trend graphs on your smartphone. Though the sensors need to be replaced every 14 days and can be slightly expensive, they are highly recommended for accurate tracking.

My father wears that little white disc on his arm! It is basically a sugar tracker. It makes life so much easier because we don't have to poke him with needles daily, and we can easily see how different foods affect his sugar in real time.
