Precocious Puberty Home A-Z Health Information Health Library A-Z Precocious Puberty Overview Precocious puberty refers to the condition characterised by premature onset of puberty before the age of 8 in girls and before age 9 in boys. This can lead to rapid growth and development changes too early in life. Causes Hormonal imbalances, abnormalities in the central nervous system, or certain tumours. Early puberty can lead to emotional and social challenges, as well as an increased risk for short stature due to early closure of growth plates. Diagnosis Blood tests to assess hormone levels, imaging studies, and sometimes a bone age assessment. Treatment Aims to halt or reverse the early onset of puberty and can include medications like GnRH analogues, which delay further development until the appropriate age.
