Glipizide can be a hunger inducer and source of weight gain because it
pushes the pancreas to produce more endogenous
insulin which stimulates
appetite.
Having taken the drug for years (before electing to start insulin
injections early) I always suspected that Glipizide dosing was inexact
relative to its effect. One is given a fixed dose by his doctor, but add
exercise and you get an unexpected low, something that often happened to me.
On the other hand, eat a little too much due to the hunger that is
stimulated by the drug and you get a high reading. Add to that the
typical rising level of blood sugar from awaking to the late morning for
many Type II's and you find that a static dose of Glipizide leaves you
with an afternoon high. Try covering that with more drug and you're
likely to get a low.
I used to shave Glipizide pills to better adjust my dosage to
conditions, and had some success with it.
