I have heard that there is a cgm on the market that lasts a year, is this true?

They have been testing a longer term one in the UK for a couple of years now - the last I really saw on it, it was lasting 6 months

However, it required going to a doctors office to have an inscission made and then it's implanted (like putting a chip in your dog or cat) and otherwise it's scanned like the current type of sensors available

Sounds promising but still a little invasive compared to the other, shorter lasting options

That is a step forward with the cgm technology.

That's an interesting question! Based on currently available information, the longest-lasting CGMs on the market have sensors that last up to 14 or 15 days before needing to be replaced. A year-long CGM hasn't been confirmed as widely available yet.

Here's what's currently out there in terms of wear duration:

Here's what's currently out there in terms of wear duration:

- Dexcom — sensor replaced every 10 days
- FreeStyle Libre 2 Plus / Libre 3 Plus — sensors last up to 15 days
- FreeStyle Libre 14-day — sensors last 14 days

Researchers are also working on noninvasive glucose monitors that don't require needles or blood at all, so the technology is definitely evolving quickly!

It's worth checking with your doctor or doing a search for the latest FDA-approved devices, as new options do come to market. Your doctor can also help figure out which CGM best fits your lifestyle and whether insurance might help cover the cost.

Yes there is an implantable cgm that lasts up to a year. But it is still in testing.
