Is morbid obesity hereditary?

Background: The influence of genetics on obesity is well established. Adoption studies and twin studies suggest that about 80% of the obesity risk is genetic.

Can obesity be genetically inherited?

One gene or many? Rarely, obesity occurs in families according to a clear inheritance pattern caused by changes in a single gene. The most commonly implicated gene is MC4R, which encodes the melanocortin 4 receptor.

Can obesity be passed down?

Science shows that genetics plays a role in obesity. Genes 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.

Can obesity run in the family?

Obesity can run in families — not because of genetics, but because of habits and environment, she says. More than a third of adults in the United States are obese, Moustaid-Moussa says.
