@hils – My grandma, who died about 50 years ago, was a classic example of uncontrolled T2 diabetes. She must have been diabetic for years without knowing it and suffered terrible leg ulcers, sometimes down to the bone and as big as your hand, and refusing to respond to treatment. They eventually cleared up when she went onto insulin and a controlled diet. I can only guess that she eventually used ‘pee sticks’ or similar, as I was only around 12 when she died, and had no idea if she tested or not. Apparently when she died of a heart attack, she was asking for sugar as she went!
