The medical costs for an obese child total about $19,000 during that child's lifetime.
That's according to a new analysis by the Duke Global Health Institute and it means the lifetime medical costs for all obese 10-year-olds in the U.S. today would be about $14 billion.
The study's lead author says the estimates highlight potential savings from obesity prevention programs to reduce or delay the onset of the problem.
He also noted the real cost of childhood obesity comes from the higher risk of those kids developing serious adult health conditions later on.
Those conditions include heart disease, Type Two diabetes and certain cancers.
The study is published in the online edition of the journal "Pediatrics."
