My grandma is 59. She smoked weed when she was a young adult, she has smoked to this day since she was a teen, and she drank alcohol for about 25-30 years. She has had type one diabetes since she was 7. In the past 5 months, she has been put in the hospital three times for her blood sugar being over a thousand. About 2 months ago, she was not getting blood to her right foot and they amputated her leg right below the knee. A couple weeks ago she had a blood clot in her arm and almost had to lose it as well. She still has it, but she has hardly any feeling in it and it is very swollen. Last week she went in for a doctors appointment and started throwing up and getting dizzy. They took her blood sugar and it was 1100. So she is yet again in the hospital. She does have diabetic ketoacidosis. I read online that blood sugars over a thousand result in a coma or death. Why isn't she in a Coma? Is this all a sign that she is going to die soon?
