Dx in DKA with BG of 540+ and A1C of 20+%. Spilling ketones, and blood was like vinegar.
Initially dx Type 1. Antibody tests came back negative, C-peptide was low.
Dx changed to 'your diabetes is so rare, atypical and interesting that medical science doesn't have an official type for it yet. Maybe they'll know what type it is 100 years down the line'.
