I read an interesting article at
www.medscape.com/viewarticle/549150?src=mp.
Basically it shows that in an observational prospective study (n=644
patients) in Australia where many "primary care physicians conform to
the prevailing clinical practice of using
metformin as first-line
phamrmacologic treatment for obese diabetics and sulfonylureas for
nonobese subjects", sulfonylureas and metformin decreases similarly the
progression of microvascular complications in nonobese and normal
weight individuals with T2 Diabetes. They state that "there is evidence
that metformin not only performs well in the nonobese individuals but
might work even better in thin patients with type 2 diabetes.
