Right -- because you have insufficient insulin available, cells cannot utilize the glucose. So your blood glucose rises. If BG is too high for too long, ketones build up, leading to diabetic ketoacidosis (bad), which is different than the ketosis (good) sought by a ketogenic dieter. People with T1D are taught to check keytones if BG is very high (CDC says > 240 mg/dL; we were taught > 300) for an extended period of time, or also when sick. https://www.cdc.gov/diabetes/basics/diabetic-ketoacidosis.html https://www.cdc.gov/diabetes/basics/diabetic-ketoacidosis.ht...
