Right now I am on insulin pens , but my good friend with diabetes type 1 is saying that insulin pump is good choice . Is it true ?
It depends really.
Most people who have switched (including me) think pumping is great.
However, as pumps are more expensive, in the UK, it is usual for those of us on pumps to have had challenges with injections.
For me this was managing my BG during exercise. For some people it was managing Dawn Phenomenon and others, especially children, need smaller doses of insulin than you can take with a pen.
I believe you still need a good justification for getting a pump although this is becoming easier.
There are downsides to having a pump depending upon how you feel being connected to a machine 24x7, your ability to understand and configure machines (there are far more variable to tweak and if you are going to get the most out of a pump, you will be tweaking) and how you cope with machine failure. Ok, this is rare but it will never ever happen at a good time so you need to be able to calmly revert back in injecting remembering what you doses are with injections.
There are also sartorial issues which may or may not be an issue for you: I really struggled at first because I felt my diabetes was on display all the time and I didn't like it. I could put my pump in a pump belt but, being small, it always left a bulge. OK. I accept it, I am vain.
So, is pumping better. Yes it is for me but it takes no less effort (maybe more) and you have to learn how to manage your diabetes almost from scratch again (whilst not forgetting what you learnt before).
I am looking forward to closed loop but again, things can fail so I am glad I have time to get used to not having it.
