I got back from A&E as my sugar levels were high (around 15mmol) and I kept getting the alarm on my CGM so thought I should get checked out. They tested my blood, said it was around the 12 mark and lowering and said i had no ketones and sent me home. However, since coming back hme I've had the alarm go off again a couple of times - it's jumped to 14.2 just as I type and I haven't eaten anything for over 12 hours. Does anyone know what is causing these weird spikes? I'm terrified I'll go into DK again.
