I was amazed that doctors could be so ignorant about this - I ended up in the ER 2 years ago with crazy high blood sugars; the ER doctors stablized me and then my primary care doctor diagnosed T2 and set me up with a treatment regimen. The nutritionist, of all people, was skeptical (I had nearly zero insulin production, yet when they finally started me on some Lantus “temporarily” had quite high insulin sensitivity) and she finally convinced my PCP to send me to an endocrinologist for a second opinion. He took about 10 seconds to say that I didn’t have Type 2 diabetes, I had Type 1. Put me on insulin therapy and I got much better within days. Followed up later with antibodies tests, which were positive, of course. But I had spent 6 weeks getting sicker and sicker, being terrified to eat anything because my blood sugars would shoot up over 400 no matter how much metformin I was prescribed, and my PCP had to be talked into even considering another possibility. Scary.
