Hi,
I tend to agree with Liz, CFRD is something to worry about, for CFers just as much for those without CF.
I'm guessing that the doctor may be coming from the point of view that given our shortened life expectancy, why worry about something that may happen in 15 years time if you'll be dead? Well, I really disagree with that stance. Damage to the retina (back of the eye), nerves, kidneys can all happen well within 10 years if someone's blood sugars are poorly controlled. Not to mention that high blood sugars suppress the immune system therefore, increasing the risk for infection and given that CFers are usually colonised with potentially life threatening bacteria in their lungs, I take my diabetes very seriously, even for the sake of my energy levels.
