Yao Defen was born on July 15th, 1972 in China. She is 7'8" tall and weighs 440 pounds.
Her massive size is due to a tumor which was on her pituitary gland but was removed to halt her growing.
Her growth started very early. At six years of age, she was already eating three times the normal amount of food compared to other children in her village. At eleven years old, she was already over six feet tall. By fifteen, she was six feet and nine inches in height.At fifteen, she saw a doctor to see if he could figure out what was causing her abnormal growth. She saw several doctors before they were finally able to diagnose the cause, however, her family was unable to do anything about it because the surgery would cost 4000 yuan ($640 USD), which they did not have.
