Leo went to the ER Sunday night for projectile vomiting. His BG that evening was 138 so not high but higher than he was reading this week without insulin. The ER dr. said they found trace ketones in urine but his BG was only 160 (way higher than when I tested him at home before we left for the ER-he was very very stressed). Are trace ketones a cause for concern even if BG is not high? I swear I think I'm having a nervous breakdown since all this started. Another massive vet bill and poor Leo being dragged again to the hospital.
