I was diagnosed with cancer of uterus about 5 weeks ago and was due to have surgery next Tuesday. I went for my pre up last Wednesday and have been self isolating since then. The diabetes nurse rang me this morning to tell me they were postponing the op as my hb1c was 85. I have to reduce my bg urgently as I need the op ASAP. I am so upset and I'm in a total panic. How do I reduce my bg quickly?
