precocious puberty
"I was diagnosed with CPP at the age of 7 and began the course of Lupron shots monthly and would go every six months for check-ups. I did get my period one time when I was 8 years old while still on the shot. I must have started treatment too late because I never reached my full adult height. Now, at the age of 22, I am right under 5 ft. (4'11). It caused a lot of weight gain as well."
