Preparing myself for a lot of work at the start. Seems to take a good few months of 'Argh!' and relearning how everything works before you begin to get more reliable results.
Hi Mike,
Like you I was on MDI for a fairly long time and I too was 'pretty well controlled' although not without hypos and feeling that I could do better but not on the insulin regime that was available. My main problem on MDI was my Basal (Lantus) I was never confident about the dose, time of dose, whether to split the dose and how long it was working in my body for (consistently). I did get complacement with my diabetes for several years i.e not testing often enough and carb counting was only introduced after 10 years of living with diabetes (it was never mentioned to me before!
😱)
I have been on my pump for 6 months now and although not a perfect cure it is much,much better than being on MDI, I never really minded taking injections it was the sometimes inconsistent readings I would get that frustrated me so much. You are right that starting pump therapy is like being diagnosed again, however your diabetes education is such that I expect you will adjust to it with few problems. The differences or problems I faced were:
1. Getting the basal rates right....and even when you think you have, you may need to change them again! (Lots of tiring fasting testing). My basal rates are massively different per hour eg 3 units per hour early morning (to combat DP) v 1 unit per hour in the afternoon, plus many other rates in between for the rest of the 24 hour period! So much better than MDI!
2. I had problems with the type and length of cannula and transfusion sets to use, I was getting high readings due to 'tunneling' with teflon so changed to metal cannulas. Also I have to pay close attention to the siting area, sometimes the absorbtion rate may not be perfect (high readings will confirm this) If I find an area that is a bit lumpy it is almost as if no insulin is working at all....at first you think that your pump is broken or you have air bubbles in your cannula or all manner of 'reasons' why you are high, instead of going back to basics.
3. Finding the right Temporary Basal rates for periods of activity/inactivity or illness...this takes time also and is really trial and error, for example when I play golf I give myself a TBR of 10% and if I'm on a long journey (plane etc) I up it to 200%. I haven't been really ill yet, just recovering from a heavy cold which didn't really affect my levels.
4. I change my cannula every 2 days, I don't leave it for 3 days as recommended because for me after 2 days the insulin doesn't deliver as well and my levels start to climb.
To think I've already missed 930 injections during my 6 month pump therapy makes me smile!
Good luck when you get it, I'm sure you will adjust with few problems.
