The slower Minimed bolus is a real advantage if you are using humalog and for
large meals where distributing the insulin over even a slightly longer period
helps me come out much more evenly, especially when you eat meals with fat,
protein, or a good sized portion. This is especially helpful if you have been
diabetic for a while and have those small undiagnosed signs of gastroparesis.
The fast delivery can also cause the insulin to burn a little bit and if you
have hypertrophy from the sensitivity to the insulin, slowing the delivery down
even a little bit will help (it will help as much as you slow it down so
obviously more is better but even a little helps)
Having said that...the faster smoother delivery is a real advantage if you
forget to bolus ahead, if you eat very fast high carb foods non fat candy, if
you are too high and need a bang to bring you down.
Since I tend to encounter both situations often, and the first ones just a
little more often than the second, the Minimed is fine. But basically, a new
diabetic might find the disetronic more comfortable, someone who has been
diabetic for a long time might find the Minimed more helpful, etc.... I suspect
most of us encounter both kinds of circumstances periodically.
