Despite being just 3-years-old, a toddler from China already weighs the equivalent of an adult, tipping the scales at a staggering 140 pounds.

Xiao Hao dwarfs his petite mom and is so big that he's been banned from several nurseries because he is a "health hazard" to other kids.

His mother, Xiao Lin, of Guangzhou, southern China, is now begging doctors to help her son lose weight.

"He means no harm he is just big and likes to play,” she said. “I take him swimming for exercise but it is hard finding trunks to fit him and even the rubber rings are too small."

Some doctors believe he may have a growth hormone disorder while others say he is a victim of China's "Little Emperor" syndrome where families are allowed only one child, who is then spoiled rotten by doting relatives.

"He is not just overweight, but very tall as well, so we may be able to treat him if it really is hormonal,” Dr. Lu Hong from the Guangdong children's hospital said. “But he cannot remain like this or his heart will never stand the strain."
