What genetic factors cause childhood obesity?

What genetic factors cause childhood obesity?

Obesity may be linked to rare genetic conditions, such as Prader Willi syndrome. Prader Willi syndrome is a disease that is present from birth (congenital). It is the most common genetic cause of severe and life-threatening childhood obesity.

Can obesity be caused by genetics?

Genetics can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight.

Is childhood obesity genetic or environmental?
