Ok, so this morning I tested FBS - 93! Good.
I took a cup of coffee, no sugar, just a little milk, and then went walking/jogging for 1 hour moderate intensity (max HR 159, average HR 113). No morning insulin yet.
After got home and tested again. No food yet. Only water. Blood sugar is 109.
Is this normal, that blood sugar increases, not decreases with exercise? Obviously exercise is very good for people with diabetes. And the rise is interesting, not alarming.
