Type 1 Diabetes
Type 1 is manageable, as is Type 2.
The QUESTION is whether she’s actively managing it. Its possible she isn’t. Human nature is a funny thing. I’ve worked under a Type 1, and have a kid that’s Type 1. I wouldn’t recommend working under one. The stress of the job (almost any job) means they won’t manage well, and you will end up working for a schizophrenic from time to time.
My kid is doing OK, but he’s a teen. His A1C has been as high as 10, which is high, but not for teens. Teens with A1C’s as high as 15 is not uncommon.
Type 1 is some bad stuff. She’s lived a long time for most I’ve known with that condition.
She could be having circulatory problems, which means possible loss of limbs or even vision. Even more serious if she had Juvenile onset.
