Using CGM data intelligently requires context.
For individuals on glucose-lowering medications, tightening ranges must be done carefully.
As lifestyle changes improve insulin sensitivity, medication doses may need adjustment to avoid overcorrection and hypoglycemia.
Consistently lower fasting values or rapid improvements should be shared with a provider — with CGM data — so treatment can be updated safely.
In these cases, CGMs are not optional. They’re protective.
For those not on medication, the risk of true hypoglycemia is much lower.
However, glucose values that are objectively normal may feel low if the body has adapted to chronic hyperglycemia.
This is not danger — it’s recalibration.
Intelligent CGM use means:
Watching trends, not isolated numbers
Adjusting gradually
Understanding medication status
Allowing the nervous system time to adapt
Data should inform thoughtful change — not provoke reaction.
