[IPu] A Bit More On Exercise ...



Hi All,
I went back to "review the books" about issues with exercise.

If you have Smart Pumping, try pages 146 - 154.

I have reproduced some of page 151 - 152 about Hyperglycemia with exercise.

"Some extra help preventing hyperglycemia
While Hypogycemia is the most common worry when it comes with exercise,
hypergycemia is also a possiblitiy.  There are a few reasons this may happen,
The two most common are:

* Insulin deficiency.  This can be a very serious concern if you have T1
diabetes.  As discussed earlier, insulin levels in the blood drop during
exercis, and with the pump you can learn to mimic these changes.  However, if
you reduce your insulin levels too much, or if for some reason your insulin
supply is interrupted and you start exercising, the fuel needs of your body
will not be met.  Remember that dropping insulin levels trigger your body to
release fuels into your bloodstream, either through glucose from your liver or
fatty acids from your fat cells.  However, since your insulin levels are low,
you will not be able to use these fuels.  Making matters worse, when insulin
levels are low, your liver will convert the fatty acids in your bloodstream
into ketones.  Suddenly you have an extraordinary amount of glucose in your
bloodstream, with ketones to boot.  As you've probably guessed, the end result
of this can be diabetic keyoacidosis.  Always be sure you're recieving insulin
from your pump before you exercise.

*Very strenuous exercise.  When you're engaged in intense bursts of very
strenuous activity, such as baskeball, hockey, weightlifting, or sprinting,
your bodywill respond in the exact opposite way it normally does to exercise.
During these strenuous activities, your body will releaseexcessive amounts of
counter-regulatory hormones, including adrenaline, which do exactlythe
opposite of insulin and work to increase your blood glucose levels.  By
bothtriggering the liver to release stored glucose and making your bodyless
sensitive to insulin, they can cause BG levels to rise rapidly.  These effects
can last for hours.  Stress from a competitive activity can also cause your
body to release these hormones.  For example, a marathon runner might take a
little extra insulin on actual race days, as opposed to practice day to
counteract the effects of his race day "jitters" and added stress.

There is another way you can end up with high BG levels after exercising.  If
you experience a low in the middle of you exercise session and don't realize
it, you can havean exercise rebound.  Just like the rebound effect from common
hypoglycemia, an exercise rebound is an increase in glucose levels triggered
by a low blood sugar episode.  If you have target readings going into your
exercise session and end with high glucose levels, and you're certain your
pump is working properly, there's a good chance you suffered a low during your
activity and your experiencing a rebound.  Do extra glucose checks during your
next session to see if you need more or less insulin."



A table format provides some examples next ... I might type these in
tomorrow.

I wonder whether these possibilities may be the cause of the high BGs listed
by list members ..... ???

Pumping Insulin also covers similar ground, in Chapter 18 Exercise, but I
actually found it a bit more complicated to read.


Hope this helps, have to get back to Leytons Tennis match now !
Warm Regards,
Janette
