Early and Late Puberty in Children
Puberty is the stage when a child’s body begins to change into an adult body. These changes include growth in height, development of body hair, voice changes in boys, and breast development in girls.
Puberty usually starts:
-
Between 8–13 years in girls
-
Between 9–14 years in boys
If puberty starts too early or too late, it may affect a child’s physical growth and emotional well-being.
There are two main types of puberty concerns in children:
Early Puberty (Precocious Puberty) When puberty starts earlier than normal.
Late Puberty (Delayed Puberty) When puberty does not start at the expected age.
Symptoms of Early and Late Puberty
Symptoms depend on whether puberty is starting too early or too late.
If you notice these signs, it is important to consult a specialist for evaluation.

Hormonal Imbalance
The brain and reproductive organs may not send or receive puberty signals at the right time.
Genetic Factors
Family history of early or late puberty can increase the chances.
Brain or Gland Conditions
Problems in the brain, thyroid, adrenal glands, or ovaries/testes may affect puberty timing.
Nutrition and Overall Health
Poor nutrition, obesity, chronic illness, or excessive weight loss can delay or trigger puberty.
