My girlfriend has type 1 diabetes. She was diagnosed at 16 and has been having to take 2-3 shots a day ever since. Shes pretty good with keeping her sugar on a normal level but heres the thing. She drinks diet drinks of course, but her food that she eats, you would never know she was diabetic! She normally eats a pretty healthy breakfast, but during the day she eats candy, eats whatever she wants for lunch & supper and just about always get deserts and always eats them. I have several relatives with type 1, and they may get a sugar free pie, or they really watch they eat but not her! She will stop by the grocery store and by snicker bars, just stuff like that. And whenever I mention that she needs to eat healthier to her she always says she will be fine just as long as she takes a little more insulin than normal. Another thing is she never exercises which I heard was something she needs to do to. Anyways, by her eating like this of rso long, my question is can it affect her health in the future?? Because she is wanting to get married, & if we do I want her to be healthy. Im really concerned and need some advice on what to tell her. Thanks a lot
