Great to hear your pancreas scan was all clear and good that they are investigating a slight abnormality in your liver.
Just to be clear, are you now injecting your insulin twice a day, morning and evening?
Libre should be available in every part of the UK to Type 1 diabetics who would like it. It may be because you are currently on a mixed insulin and not diagnosed Type 1 that you don't qualify for it yet. Hopefully that will change if/when you are confirmed Type 1.
Libre is a wonderful bit of kit BUT it has it's limitations. Many of us apply it a day before we activate it to allow the tissue that the filament is injected into to react to a foreign body in it's midst and then settle down as some of us found the first day or so of reading were often less reliable. Giving it a day after application to settle gave better results from the off once it was activated.
I will post a link to a thread about the limitations which is worth reading, particularly about "compression lows" which are false low readings during the night if you lie on the sensor arm. You should check any low or high reading that it gives with a finger prick reading if the way you feel doesn't correspond to the reading and you should always assess recovery from a hypo with a finger prick 15 mins after treatment and ignore Libre, because Libre will almost always show your levels continuing to drop for a further 30+ mins whereas a finger prick reading after 15 mins will usually show you are recovering. If you rely on the Libre at this time, it will almost certainly panic you and cause you to over treat hypos and end up too high which of course then needs insulin to bring you down again and that can set you on a roller coaster, whereas a finger prick will usually reassure you that your initial hypo treatment is working. Those are the main times when Libre is unreliable and needs to be double checked.
Moderator Note: This helpful reply was copied from another thread as it details some of the commonly experienced limitations of continuous glucose sensors.
My blood sugar has been in perfect range for days now, but although I haven't changed anything, I'm starting to get very short periods of hypos while I sleep and this morning I had a hypo alarm.
If these are very short periods of lows and occur overnight, they are more likely to be compression lows - when pressure is applied to a sensor, it will report a false low. The reason I say this is more likely to happen at...
It takes time and trial and error to find the best placement to reduce compression lows and where you won't catch it on door frames or bra straps etc, but Abbott are pretty good about replacing ones that come unstuck or are unreliable. Usually if it is consistently within 2mmols of your finger prick readings when levels are reasonably stable then it is useable. More that 2mmols out on 3 occasions and Abbott will usually replace.
I find for my body, Libre usually consistently reads lower than my finger prick by about a half to one mmol when levels are stable, which is perfectly acceptable and I am very happy to base all my insulin doses on the readings it gives me. Generally I will do a couple of finger prick checks in the first couple of days of a new sensor when levels have been stable for about half an hour to make sure it isn't way out and after that I am happy.
