Sorry if this an issue which is clear from other threads, but I'm not good with forums and rarely submit posts, although I've followed this forum for a long time. I'm 65 and type 1 for 52 years, on insulin throughout. Libre has improved my HBA1c levels to best ever, 42 (6.0%). However I've been put on a steroid for a liver problem, autoimmune hepatitis, 9mg of budesonide (Cortiment), and it is causing havoc to my levels after only two days. I've had no carbohydrate all day and took 25% more insulin this morning, but level was not falling below 12 so tonight I doubled my usual insulin dose, and my level is still between 12 and 13. I had a different steroid prednisolone a few years ago for another problem, polymyalgia rheumatica, and that also neede an increase in insulin dose, but today is getting a bit worrying. Anyone any suggestions? I'm on quite an old insulin regime of 30 units Hypurin Porcine 30/70 mix am and 40 units Hypurin Isophane pm, but until now it has been working extremely well.
