Diabetic father experiencing severe weight loss

My 84 year old father lost his pancreas 12 years ago and is insulin dependent.

He and my mother are sugar addicts; their behavior gives it away.  

At family reunions they can't have one piece of pie, they have large samples of every dessert.  I've peeped into their fridge many times and its loaded with ice cream, candy, orange juice, etc.   They deny sugar intake to me and I'm certain that they aren't truthful to physicians.

Dad's lost weight like crazy.  He's 6'2" and weighs around 130 lbs.

I understand the basics about diabetes but don't know if his high sugar intake to blame for the weight loss?  If so my next step is intervention and drag him to a nutritionist.

I'd really appreciate your input on this one.

Thanks,

Mike

Your father is slowly killing himself with that type of sugar consumption.  It is very true that high blood sugar will lead to weight loss, but it also leads to kidney failure and other system failures.  I wonder is he knows or cares about this, the best thing I can suggest is to talk to him and make him see a nutritionist asap, and maybe you should advise his docs about his eating habits and see if they can recommend anything to help fix your current problem.  Good luck.
