I am concerned about my husbands chance of getting diabetes. 2 of his sisters have it and he has been testing himself due to concerns about it. Over the last few weeks when he has tested himself (using his sisters tester), the lowest his glucose has been is 130. This was after not eating all night and checking it in the morning before eating. It has been as high as 480. His doctor has been checking him with yearly blood and urine tests for diabetes and he has always been "borderline". I am concerned that he now not just "borderline", due to his high glucose numbers. His glucose has been averaging 270 which I know is high. My concerns are because I have seen how his sister through non compliance is now in end stage renal failure and is on dialysis 3 times a week. He recently had a small cut on his finger that took weeks to heal because of an infection that developed. I know being slow to heal is one of the signs of diabetes. Should I be worried?:confused:
