I was recently told I will develop CFRD sometime in the future. I also drink coke morning, noon & night and nothing else - have for years & years. I was told by my endocinologist that cutting down on empty sugars (sugary sodas) may increase the chances that I will develop full blown CFRD at an earlier date because of the strain it puts on your pancreas. I am currently not diabetic, just glucose intolerant. If you eat tons of sugar, it causes your pancreas to produce a lot of insulin to counteract the sugar. I am not saying don't eat sugar, just moderate your sugar intake. As I am a serious coke drinker, I have found it very difficult to cut down on it. I hate diet-YUCK! I can tolerate diet 7-up, so I maybe have cut my coke drinking in half. When I become diabetic I will probably be able to eat & drink anything I want because in CFRD you tailor the insulin to what you eat. But for now, I don't want diabetes and since I am already showing signs that my pancreas is having trouble producing insulin, I want to be nice to it. So, if you have no problems with CFRD and everything in that area is all good - drink as much coke as you want! It can't cause you to become diabetic, CF affects the production of enzymes in the pancreas and after a while the rest of the pancreas can shut down too, that's what causes CFRD.
