Obese or overweight teenagers are at a greater risk of developing gallstones compared to teenagers who are of healthy weight.

The risk was greater, up to six times more likely among those classified as extremely obese.
Stating that the rates of gallstone cases were rising among children, lead researcher Corinna Koebnick said, “Although gallstones are relatively common in obese adults, gallstones in children and adolescents have been historically rare. These findings add to an alarming trend - youth who are obese or extremely obese are more likely to have diseases we normally think of as adult conditions.”
