What should you know about pathophysiology of precocious puberty?

Puberty is coordinated by signals from the brain to the pituitary gland, followed by hormones from the ovaries or testes. In central precocious puberty, this signalling pathway switches on early. In another pattern, the body makes sex hormones without the usual early activation of the brain pathway. These hormones can lead to breast development, pubic or underarm hair, body odour, acne, growth acceleration or menstrual bleeding, depending on the child’s body and the hormones involved.

A clinician considers the sequence of changes, growth pattern, family history and any medicines or hormone exposure. Testing may include examination, growth review, bone-age assessment and selected hormone tests. A Female Hormone Blood Panel may be discussed when blood hormone levels need clarification.

Arrange a paediatric or endocrinology assessment if puberty changes appear unusually early or progress quickly. Keep a simple record of when each change began, including growth spurts, breast or testicular development, hair, acne and bleeding. Bring the child’s medication list and mention creams, supplements or household hormone products. Treatment depends on the cause, the child’s age, the pace of change and predicted effects on growth; some children need monitoring, while others may be offered medicine to pause pubertal progression.

Seek prompt medical advice for rapid progression, vaginal bleeding, severe headache, vision changes, vomiting, seizures or a new neurological change. These features do not identify one cause, but they can signal a need for urgent assessment. Sudden changes after possible hormone exposure also deserve timely advice.

Which physical changes suggest central or peripheral precocious puberty? What tests are appropriate now? Could a medicine, supplement or hormone exposure be contributing? How might early puberty affect growth and emotional wellbeing? When should we return for review?
