My 21 year old boyfriend has had type 1 diabetes since age 13. Two years ago, when I first met him, he weighed 275 pounds and now he weighs in at about 190 pounds. He does not control his diabetes at all. The last time we checked his blood sugar was above 500 mg/dl [27.8 mmol/L]. I have noticed a lot of muscle loss, and his eyes look sunken in. Please help me with information that would scare him into listening to me about the seriousness of diabetes.
