I recently had to check my urine and today I had large keytones but my blood sugar is normal? I didn’t quite understand how they work but usually they’re negative or just a trace..is this bad?? My dietician said when they’re higher I need more carbs but I had a good amount of carbs today. My blood sugars 5.2mmol. Any advice will help as I can’t get ahold of my doctor🙈 been trying since lunch time to get through!
