I've got about two weeks in on the Dexcom G4 Platinum and I'm learning some interesting things with it.
From what I am looking at on the Dexcom Studio software my body seems to be behaving more and more like a true type one diabetic. I eat carbohydrates and my blood sugar goes up and doesn't come down without injecting insulin.
With careful monitoring, good diet and using insulin I get good results. I can keep my blood sugar right where it needs to be, between 130 and 80 mg/dl.
Some days my pancreas decides to play nice, some days it doesn't. Usually it waits till I decide it's not going to behave and hit the Lantus or Apidra insulin and then it decides to kick in. These times lead to the bad.
And depending on what I eat, things can get real ugly real quick. Cinnamon rolls for Sunday breakfast are now definitely off the list cause these lead to the just plain ugly.
In short, just like doctors have said for years, eat right, exercise more.
