Re: [IP] RE:Dawn phenomenon? Is it really?

 The dawn effect can be coped with by setting the basal rate to deliver enough
insulin to prevent it.
 To do so it is necessary to test your fasting blood sugar throughout the night.
The tests will indicate when you have the dawn effect and basal insulin can be
increased to cover it. If you have an endocrinologist, they can best explain
what has to be done. They might be able to provide a loaner CGM that would make
the test simpler to do. One of the main things about the test is to have no
bolus insulin remaining when you start.

 Like you said, not much has been said about the actual ABSORPTION of insulin
being a factor,
 I agree in fact I believe that it is the major flaw with insulin pumps. Since
going on the pump, the insulin delivering infusion sets have not been reliable.
I took shots for 44 years and never had the problems that l have had with
infusion sets. Steel needle SureTs have worked best for me because the delivery
is as good as a shot yet the problem of pooling takes over a portion of my body
and I must relocate. It takes about a year before I can use the area again. That
makes me wonder if the insulin delivery isn't too slow because as compared to
shots where the insulin delivery is really fast.

 I agree that pumps are only a partial solution to the problem and unless they
can come up with a better delivery system, the future closed loop system can
expect the same problems as the current pumps., namely unreliable absorption.

 The CGM is an excellent tool for tracking blood sugar readings plus it is
fantastic for setting both bolus and basal rates.
