2 million U.S. children
between the ages of 12 and 19 have a pre-diabetic condition linked to obesity

cardiovascular problems.
The Centers for Disease Control and Prevention, working with the National

glucose) in nearly 1,000 teens.

in abnormal heart rhythms.
This problem specifically affects the right ventricle. It was found in nearly 90
percent of ultra-endurance athletes.
