Re: [IPk] my response to the DAFNE trial published in the BMJ
To me the question of whether or not a long-acting insulin can match
your regular daily insulin requirements misses the single greatest
advantage of the pump, at least for me.
I hate long-acting insulin with a vengeance - I still remember (4 years
ago now, and only one year of MDI since diagnosis) the horrors of the
ongoing hypos - sense of being dragged into the depths when I least
expected it by the silent claws of the long-acting insulin.
I can't be the only person whose insulin requirements are so sensitive
to exercise, stress etc - and the exercise does not have to be
something you think of as major exercise - indeed my major form of
exercise is walking - I do sometimes go on hikes for several hours, in
which case I certainly have to adjust the pump rate down, but all sorts
of things are exercise and reduce my insulin requirement temporarily:
for example if I just have to rush around picking up shopping from
different shops, then carry a supermarket load up the 3 flights of
stairs to our flat, respond to sudden 'urgent' requests from husband or
kids to go somewhere or do something, or rush around at work. I work in
a large hospital - and some days mostly sit at my desk, other days, due
to unpredictable factors may run to the medical school library at the
other end of the building, up 7 flights of stairs (the lifts are so
slow to come - I have no patience) for a meeting with colleagues in
another department, or a friend suddenly turns up from out of town and
we go for a walk together - i.e. not planned deliberate exercise at
times I could foresee - yet a series of such activities in quick
succession could easily send me badly hypo in the old days of MDI. A
life with no spontaneity seems to me cruelly restrictive, and a life
with none of what for me is normal exercise, obtained in the course of
my daily activities, would also not be physically healthy.
One day when I was still on MDI, my endocrinologist asked me why I
didn't seem able to eat at predictable times - he understood about
lunch at work, but said "What about breakfast, at least you should
always be able to eat breakfast at the same time?" I then told him the
story of that particular morning when one of our teenage daughters had
overslept and needed driving quickly in order to get to school in time
for an important test - he then laughed and said that his similarly
aged son had done something comparable the same day, and he too had not
eaten his breakfast as intended (and as a non-diabetic not thought
twice about that) - since then he has clearly realized that I too have
a life, and never once expected me to have a rigid routine.
