Yes. CGMs measure the glucose concentration in interstitial fluid, which will lag behind blood glucose levels. All CGMs work like this (you'd have to insert the sensor into an artery to get around that or something).My Doctor says they are no good at preventing a Hypo because they are all half an hour behind. Is this true?
That's not gonna happen, sorry. The NHS will pay for pumps if certain conditions are met (severe hypos, or failure to control HbA1c despite patient's best efforts with MDI) but there are no guidelines for CGMs. InfoWill put my case to my Consultant and see what he says about NHS helping to fund it.
