I came across a few studies a while back linking glucosamine with
insulin resistance. I've also come across studies showing no effect.
What type of diabetes does your mom have? I'd be more worried with type
II. I would assume, based on the general patterns for all life on earth,
that there's a normal (aka bell) curve with this compound and some
people will be more affected than others. There also may be a subgroup
that is more severely affected and not enough research has been done yet
to elucidate that the outliers are actually a subgroup and their stats
should not be discarded from the statistical data set. This is a study
that causes me condern with regards to your mother and her diabetes:

ctPlus&list_uids=16818461&query_hl=1&itool=pubmed_docsum

If it were my mother, I would /strongly/ discourage her from continuing
to use glucosamine. If her doctor was encouraging it without knowing the
research with regards to people with her health problems, then I'd find
a new doctor.

Jan,

I'm a Type 1 (IDDM) and I've taken glucosamine chondritin MSM in the past
and it doesn't contain enough glucose in it to effect a diabetics readings.
If
your mom has good control now she should be able to handle the small
increase.

Best advice is for her to take it and test a bit more frequently the first
week and
see what it's doing.  This I can defiantely tell you. Pain increases your
glucose
FAR WORSE then the glucosamine ever would.

Best of Luck...
