Blood sugar yo-yo after meals
So a CGM has been an eye opener. It gives me a real-time window on glucose levels whereas finger-stick measurements gave me limited snapshots
I'm amazed at how quickly even light exercise after meals can bring down glucose. Only problem for me is the yo-yo effect.
I'd have lunch, then hop on the treadmill for 25 mins. Predictably, glucose drops from 160 to 72 during that time.
After I get off, glucose climbs back even higher to 164 before quickly falling off again to 123. All this in less than two hours.
This happens predictably, there's always a double peak. If I hop on the treadmill again, the second peak is smaller, but still there.
Glucose levels always drop below 140 within 2 hours. Can I ignore the yo-yo effect?
