does anybody have issues with sudden/rapid dehydration, especially muscle shrinkage?

If your blood sugar levels are too high for a long period, your cells are become resistant to the intake of sugar, or insulin resistant.

that's what blood results are showing ...they said sumthing about long term levels of something lol can't remember but im on a diet and i think because of my working out and doing a physically demanding job 6 days a week i was eating too much carbohydrate and my body was struggling to produce enough insulin and at other times over producing...strange????? thanx
