What is a CGM?
A CGM (continuous glucose monitor) allows you to measure blood sugar levels in real time. Using a CGM makes it easy to track blood sugar at all hours. A traditional blood sugar meter gives you a single blood sugar reading for one point in time. A CGM, on the other hand, tells the story of your blood sugar levels as you move through your day and night. You’ll get a picture of how different things, like the food you eat and the meds you take, affect your levels. Having this constant feedback can help you make more informed decisions.
How does it work?
The CGM uses a tiny wire placed under your skin to measure sugar levels in tissue fluids (also called interstitial fluid). The wire is connected to a transmitter. The transmitter sends the information to your CGM reader or a smartphone. Because it constantly monitors your blood sugar levels, you get 24/7 access to your numbers.
Reasons to try a CGM:
- Learn how different foods impact your blood sugar.
- Understand how activity impacts your blood sugar.
- Find out how much of the day your blood sugar is in range.
- Gain knowledge on what, besides food and exercise, impacts your blood sugar.
- Learn more about your overnight levels.
- Get alerts overnight when you’re trending toward a low.
- Uncover why your blood sugar is high when you wake up.
- Share information about your highs and lows with loved ones.
- Observe the impact of medications on your blood sugar.
- Help your doctor or coach work with you to understand and control your blood sugar.
The 24/7 data offers insight into what may be causing ups and downs. For example, it may show that you need to adjust medication or insulin.
