Diabetic Retinopathy Treatment Care

What is a Diabetes Educator?
How long does it take? bachelors? masters?
Is the field difficult?

I have low blood sugar and I was wondering if that could ever, possibly turn into diabetes. 4 or 5 sources said yes, and 1 or 2 said no. Just want to clear things up!

I am trying to find out more about the history of gestational diabetes. I am finding plenty of articles about people having a personal or family history of it, but what I am looking for is when the medical community starting using the phrase “gestational diabetes” rather than only talking about diabetes and pregnancy. I found an article from 1986 in a medical journal that mentions it, but nothing before that.
Does anybody know where there might be more information about this?
