Treatment will begin only after you and your child have thoroughly discussed the treatment with the doctor. Children treated with growth hormone grow an average of 2 inches from what was expected. But this happens only after many years of treatment. If your child is treated, his or her growth response will be measured after 6 to 12 months. This will help the doctor decide if treatment should continue. Complications might also happen. Rare complications include increased pressure inside the skull. Or, the top part of the thigh bone might slip out of place. It is not known what other complications might happen over time. If complications happen, treatment might be stopped, temporarily or permanently.
