precocious puberty
"I was diagnosed with precocious puberty when I was 8 and started getting a lupron shot once a month. It stopped all signs of puberty except the mood swings which often worsened in the week before I got a shot. After 3 years I was taken off the medicine and started puberty normally. I had continued to grow taller throughout that time and am now 5'1", my grandmother and cousin both had precocious puberty as well and neither were treated, they both stopped growing around age nine and neither reached five feet."
