Puberty is often recognised as a transition from childhood to adulthood. Puberty occurs as a result of hormonal changes. The main hormones involved in puberty are oestrogen, progesterone and testosterone.
Puberty usually starts between the ages of 8 and 16 years and can last anywhere from 18 months to 5 years.
Although experiences of puberty vary widely, most changes are experienced by everyone, but to different degrees. If you’re worried or struggling, seek help from an adult you trust, a doctor or a support service.
