It is not the first time when it has been said that obesity brings along a lot many health complications. A recent research has found yet another problem of obesity and that is of gallstones.

Gallstones are pebble-like substances made of cholesterol in gall bladder. The gall stones can differ in size, as they can be as small as a grain of sand and can be as big as a golf ball. Kaiser Permanente, who is a UK obesity expert, has found that obese children are more likely to suffer from the problem of gallstones.

In order to reach at the above given result, Permanente said that he had assessed 510,000 children who were aged between 10 and 19 years. The study, which has also been published in the Journal of Pediatric Gastroenterology and Nutrition, found that 766 children were having gallstones.

Permanente explained that children who were moderately obese were four times more at the risk of having gallstones. However, the risk was six times high among extremely obese children.

"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", said Corinna Koebnick, who is the lead researcher of the study.
