In girls getting treatment for early puberty, how fast they're growing after a year is linked to their height, weight, and how much weight they've gained during that time.

For girls who start puberty too early, a treatment using certain hormones can help them grow taller than expected — especially if they get a combo of two hormone treatments.

In girls who start puberty too early and are treated with a certain hormone therapy, those who are taller than average at the start, gain more weight in the first 6 months, or have higher levels of a growth-related hormone might grow faster during treatment — which could help doctors spot who will respond best early on.

Girls with early puberty who take certain hormone treatments might grow more slowly later on if their bones are maturing too fast — this could mean they stop growing sooner than others.

For girls with early puberty who are treated with two hormones (one for puberty and one for growth), the ones who grow more during treatment tend to have started with a lower predicted adult height and more mature bones. How long or how much growth hormone they take doesn’t seem to affect how much they grow.

Giving certain hormone treatments to girls who start puberty too early can help them grow taller as adults.
