Should you wear a glucose sensor if you don't have diabetes?
Two weeks with a bits Patch can teach you a lot. Here is what the data can and cannot tell you.
Continuous glucose sensors were built for people with diabetes. Now anyone can stick one on their arm and watch their blood sugar react to breakfast. The question is whether the reaction tells you anything worth knowing.
What a healthy curve looks like
In someone without diabetes, glucose rises after a meal, often to 140 mg/dL or a little more, and returns to baseline within two hours. That rise is digestion, not a problem. The bits app never scores normal post-meal rises as bad.
What the data is good for
- Spotting a meal that sends you much higher, for much longer, than others.
- Seeing how a short walk after eating flattens the curve.
- Noticing how a bad night's sleep changes the next day's readings.
How we suggest using it
Wear one sensor for two weeks. Eat normally for the first week and experiment in the second. Write down the three things you learned, keep the habits, and come back in a year if you are curious.
