I have been aT1 diabetic for 40 years and last year was put on medotronic pump, recently I have been getting high BSs for no apparent reason so I take an extra bolus I do not play around with my basal amounts cos the hospital sets them, it still does not go down well very slowly, I have a libre sensor for monitoring, I change the site of my catheter so it is not that, any advice? Can antibiotics effect levels as I am on them for 5 days with a urine infection.
