Puberty in girls involves a set of coordinated physical and hormonal changes that prepare the body for reproductive maturity, mainly regulated by estrogen.
Major changes include:
- Breast development
One of the earliest visible signs, indicating hormonal activity has begun.
- Onset of menstruation (menarche)
The start of the menstrual cycle, showing that the reproductive system is functioning.
- Growth spurt
Increase in height, usually earlier than in boys.
- Widening of hips
Body shape changes to support reproductive functions.
- Hair growth
Appearance of hair in the underarm and pubic regions.
- Skin changes
Oil glands become more active, sometimes leading to acne.
- Fat distribution
Increase in body fat around hips and thighs, contributing to body shape.
Clarification:
The timing and sequence of these changes can vary, but all are normal indicators of healthy development.
