[IP] Downward pressure on BG

Dear group,
I think there is some confusion in the terminology being
used to explain the physiology of food absorption and
glucose use. There is no downward pressure involved unless
osmotic pressure or hydrostatic pressures are what is
intended. Glucose in the blood needs insulin as a
transporter to carry into the cell where it can be used. If
the blood glucose is high because of insufficient,
deficient, or non-existent insulin, or the cellular wall is
resistant to insufficient or deficient insulin, then the
cell itself is hypoglycemic. The liver will try to dump
glucose (if there is any glycogen stored there to be broken
down), and the liver will influence the breakdown of fats to
make glucose (in the absence of insulin), and stress
hormones can trigger protein conversion to glucose. The high
glucose will pull water out of the cells trying to dilute
the higher than normal blood glucose, increasing the blood
volume and the amount of fluid moving through the kidneys
(increased urination and continued dehydration).

Might this be what the original comment was about? I see no
relationship, however to pressure and hypoglycemia, other
than a possible initial blood pressure increase from an
adrenalin release that tries to raise the heart rate and BP
to get more glucose transported to the brain, but with
insufficient glucose to feed the brain, that BP increase may
lead to a blood pressure decrease. Someone with heart or
kidney disease might not fare very well to this compensatory

Other medical responses?????
