Quick answer
What is Precocious (early) puberty?
Precocious puberty means the physical changes of puberty begin unusually early — broadly, before around age 8 in girls and age 9 in boys. It involves the early development of features such as breast development or periods in girls, testicular and penis enlargement in boys, along with pubic hair, body odour, acne, and an early growth spurt.
- How it is treated: Assessment aims to confirm that puberty has genuinely started early, to work out the type, and to look for any underlying cause — through a history, examination, blood tests, a hand X-ray to assess bone age, and, in some cases, scans (such as of the brain or other glands).
- Self-care: This is a condition requiring medical assessment rather than lifestyle management.
- When to seek help: See a GP if a child shows signs of puberty unusually early (before about 8 in girls or 9 in boys), for assessment to check for any underlying cause and consider whether treatment is needed.
What it is
Precocious puberty means the physical changes of puberty begin unusually early — broadly, before around age 8 in girls and age 9 in boys. It involves the early development of features such as breast development or periods in girls, testicular and penis enlargement in boys, along with pubic hair, body odour, acne, and an early growth spurt. Because puberty involves a growth spurt followed by the bones finishing growing, starting too early can, if untreated, sometimes lead to a shorter final adult height, as well as having emotional and social effects for a child who is developing ahead of their peers. There are two main types: one driven by the brain's hormonal signals starting early (which in girls is often just an early-but-normal process with no serious cause, but is always assessed), and one driven by hormones from elsewhere. Sometimes only one feature develops early (such as breast development or pubic hair alone), which can be a normal variation. Assessment is important to identify any underlying cause.
How it is treated
Assessment aims to confirm that puberty has genuinely started early, to work out the type, and to look for any underlying cause — through a history, examination, blood tests, a hand X-ray to assess bone age, and, in some cases, scans (such as of the brain or other glands). Whether treatment is needed depends on the cause, the age, how fast it is progressing, and the likely effect on final height and wellbeing. For the common brain-driven type with no serious cause, treatment (with medicines that pause the pubertal process) may be offered, particularly in younger children or where rapid progression risks a reduced final height or causes distress, and is stopped at an appropriate age to allow puberty to resume normally. Where an underlying cause is found, it is treated. Support for the child and family, including with the emotional and social aspects, is important. Care is guided by a specialist (paediatric endocrinologist). The reassuring message is that many cases, especially in girls, have no serious underlying cause, but assessment ensures the right care.

Beyond medication
Lifestyle and self-care
This is a condition requiring medical assessment rather than lifestyle management. Support for the child's emotional and social wellbeing, given they are developing ahead of peers, is an important part of care alongside any medical treatment.
When to get help
When to see a doctor
See a GP if a child shows signs of puberty unusually early (before about 8 in girls or 9 in boys), for assessment to check for any underlying cause and consider whether treatment is needed.

Answers
Precocious (early) puberty: frequently asked questions
What causes early puberty?
It can be driven by the brain's hormonal signals starting early (often with no serious cause in girls, but always assessed) or by hormones from elsewhere. Sometimes only one feature develops early, which can be a normal variation. Assessment identifies any underlying cause.
Does early puberty need treatment?
It depends on the cause, age, how fast it is progressing, and the effect on final height and wellbeing. Medicines that pause puberty may be offered for some children, and any underlying cause is treated. Support for the child is important.
