My 80 year old father has diabetes and is dependent on insulin shots. For the past 3 years he has not been eating right and has blood glucose drops in the 50 range. He seems to believe that taking a high glucose drink or candy is the answer. Yes, it fixes the low, but I feel this is not fixing the eating problem. No matter how gently I try to talk to him about this, he becomes very angry immediately. I am only concerned for his welfare and I want to help. He is showing early signs of dementia and can be very volatile at times. Any suggestions would be appreciated.
