A 16-year-old teenager spent $2,350 on growth therapy sessions over six months, but lost the 1.4 centimeters he had gained in just two weeks after quitting the therapy. One Chinese teenager convinced his family to spend about 16,700 yuan ($2,350) on growth therapy sessions over a period of six months, but he was ultimately disappointed because the 1.4 centimeter he gained during that period of time vanished soon after the therapy stopped. The boy’s father, surnamed Huang, told the South China Morning Post that the teen’s height had increased from 165 cm to 166.4 cm in six months, but that extra 1.4 cm went away in the two weeks after the growth therapy ended. Mr. Huang said that he took his son to growth therapy sessions every week. Wu Xueyan, Chief Physician of the Department of Endocrinology at Peking Union Medical College Hospital, said that forced physical stretching was not a scientifically-proven growth therapy.
