Yes, my father was though it he was type 2 and it didnt seem to stop him eating what he wanted. They ate cake most days and he loved butter and jam on his toast.
I am borderline at the moment so have cut out cake and biscuits and now have resorted to making recipes with dates, coconut,cacao etc to satisfy my sweet tooth - very little added sugar, and i steer clear of recipes/processed foods with a lot of sugar, so that it will improve - I DO walk every day and am thin but hereditary seems to play such a large part in many of these diseases.
On paper, no. However, I am pretty sure that my mother was, but undiagnosed. I also have a suspicion that my father's grandmother may have been as she was blind and in a wheelchair. Back in the late 1800s there would have been no diagnosis or treatment and I doubt that they went to the doctor much - they just got on with it. I have no oral history, just a couple of photos. My siblings and I just ty to work things out from the little we know.
My Dad has it, but he is pretty well controlled. He watches his diet. Because of family history, I have a pretty good chance of getting it. I am doing all that I can to prevent it happening. I have a glucose tolerance test every year, watch my diet and exercise. Our son has Type 1 diabetes with absolutely no family history.
My father was obese and an alcoholic before he died. He was diagnosed as a diabetic . I think it was still diet controlled as we found a glucometer, for measuring blood sugar, but no insulin or syringes when we cleaned up his belongings.
Luckily neither had it, nor in my direct family. I did feel really sorry for an elderly lady living in the retirement village my late mother lived in. She was very thin, ate like a sparrow and never veered from her special diet yet she had an exceptionally high reading all the time.
My parents aren't but my grandparents, uncle and brother all were/are. Insulin dependent diabetes runs in my family. I was brought up on a strict diet because my brother is only 2 years older than me. It was horrible when we'd go to a party and get a lolly bag to take home. He'd cry and my twin sister and I would have to hide it in our bedroom and were only allowed to eat it when he wasn't at home. He was diagnosed when he was 7 and we were 5 so we didn't have the lolly filled childhood others had (I'm making up for it now though)
