A friend was just diagnosed with Type 2, and I am wondering if she might have type 1 instead. She had gestational diabetes with her daughter, but had a fasting glucose test last year that was fine. She is in her early 50s In October she started feeling terrible and suddenly lost around 7 pounds. She was "feeling drunk" after eating and was generally miserable. She went to her doctor with a glucose of over 300 and was put on Metformin. Blood sugars remained over 300 for at least three weeks and she found out that her a1C at diagnosis was 13. She recently switched to glucophage and has had somewhat better numbers (in the 200s). Is it possible for type 2 to have such a quick onset? She hasn't had a c-peptide test--should I tell her to get one? Thanks for you insight!
