Hi Linz,
This is a good site to check out for pump info and what they do
http://www.input.me.uk/
A pump is only as good as the user though, ie, it's not plug and play. So in a nutshell you only get out what you put in.
You need a good understanding of carb counting and how dif types of foods effect your blood sugars.
There is a lot of hard work involved in pumping as well, as in a lot of basal testing and adjusting the pump to suit your own needs. Which does mean quite a few sleepless nights to start with.
As long as you understand what you need to do with the data from basal testing and can carb count then you will be fine but if you can't on MDI work out your own adjustments or understand what you are doing then pumping wont help you. There are many who's main problem is they do not have a flat basal so no basal insulin will match it thus all the problems of the yoyo effect on blood sugars.
That's the warts :lol:
But if you put in the hard work then pumping is fantastic and the quality of life has the wow factor :thumbup:
A very good book for any pumper to have is pumping insulin by John Walsh. It's known as the pumpers Bible and worth it's weight in gold. Can be bought from Amazon
