Current CGMs (Continuous Glucose Monitors) are amazingly non-invasive and easy to use. I'm wearing one right now and I can't feel it.<p>I'm using the Freestyle Libre 3. It's the size of a penny on my upper arm. I don't have to replace it for 14 days, so I'm only really aware of it 2x per month.<p>It transmits the signal to my phone via bluetooth. So essentially it's like your phone reads your blood glucose live but every 14 days you need to wipe your upper arm with an alcohol wipe and stick a new one in. The process is completely painless and takes 1 minute or so once you've done it a few times.<p>Any doctor can prescribe you a CGM and they're like $70-100 per 14 day period, depending on brand/location/insurance. If you're diabetic your insurance will likely pay for it.<p>Should you be on the fence I absolutely recommend you just get one. Pay it out of pocket just to learn how you respond to the things you eat and drink.
When they first come to the market, it wouldn’t surprise me if they were more about trends.<p>It won’t tell you any kind of absolute measurement, maybe just some sort of rough guide to how fast it’s going up/down of if things are relatively stable.<p>Enough to prove useful and know when you need to test with a real test, but not a full testing solution itself.
