Congestive heart failure
From WikiCover
More than 4.5 million Americans suffer from congestive heart failure, which also is one of the most common complications of type 2 diabetes. CHF is a condition in which the heart cannot pump enough blood to the body's other organs, which can result in fluid retention, or edema. It is also well known that TZDs can cause some fluid retention, which can lead to or worsen CHF.
