Well loss of hypo awareness symptoms is certainly one as you have highlighted Stephanie, but there are many more reasons to why pump therapy might be offered.
Over the last year we have had countless members change from MDI to pumps, some have only been diagnosed for a year or two (and have good diabetes control) but still have been offered the chance of a pump to improve their quality of life, only recently I've been provisionally approved myself for a pump due to the fact that I'm having on-going injection site problems, by changing over will mean I will go from injecting up to 15 times over 3 day to inserting a cannula every 3 days, this will help my diabetes control in the long term as it will give my sites time to recover from the relentless needle stick injuries, although I've never really had any issues with the injecting insulin, especially since the arrival of the modern insulin pens and small gauge needles.
