An enlarged heart can occur of one does not eat healthy and exercise or does not get proper treatment for the issue. Scientists have found that having an enlarged heart can also increase the chance of getting diabetes.

"High-blood-pressure patients treated for enlarged heart (left ventricular hypertrophy, LVH) who have regression or prevention of LVH may also have a better chance of preventing diabetes. Led by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, the research is published in the November Hypertension, a journal of the American Heart Association."
