Puberty: The Time of Physical and Emotional Changes in Girls

Puberty is the time when a child’s body begins to mature and develop into that of an adult. In girls, puberty typically starts between the ages of 8 and 13 and lasts until the age of 14 to 19. During this time, girls experience a wide range of physical and emotional changes. In this article, we will discuss the changes seen in girls at the time of puberty, including physical changes, emotional changes, and the onset of menstruation.


Physical Changes


Growth: One of the most notable physical changes during puberty is growth. Girls will experience a significant increase in height and will go through a growth spurt. They may grow as much as 4 inches per year during this period.


Body Shape: As girls enter puberty, their body shape begins to change. They will develop a more curvy shape, with more hips, breasts, and a wider waist. They will also start to develop more body fat.


Hair Growth: Girls will start to notice hair growth in several areas, such as under their arms, on their legs, and around the pubic area. They will also experience an increase in oil production, which can lead to acne.


Breast Development: Breast development is one of the first signs of puberty in girls. The breasts will start to grow and develop until they reach their adult size.


Emotional Changes


Mood Swings: Girls may experience emotional changes during puberty, such as mood swings and irritability. Hormonal changes in the body can cause fluctuations in mood, which can make girls feel out of control.

Mood Swings

Self-consciousness: As girls’ bodies change, they may become self-conscious and worried about how they look. This can lead to feelings of insecurity and low self-esteem.


Social Changes: Puberty can also be a challenging time socially, as girls may feel pressure to conform to societal norms and expectations, which can cause feelings of stress and anxiety.


Onset of Menstruation

Menstrual Cycyle

Menarche: Menarche is the first menstrual period. It typically occurs between the ages of 11 and 14, but can occur as early as age 8 or as late as age 16.


Cycle: Menstrual cycles typically last 28 days, but can range from 21 to 35 days. The duration of bleeding can also vary, lasting anywhere from 2 to 7 days.


Hormonal regulation: The menstrual cycle is regulated by hormones such as estrogen and progesterone. These hormones regulate the growth and shedding of the lining of the uterus.




Puberty is a time of significant physical and emotional changes for girls. Physical changes include growth, body shape, hair growth, and breast development, while emotional changes include mood swings, self-consciousness, and social pressure. The onset of menstruation, or menarche, is also a significant event during puberty and is regulated by hormones such as estrogen and progesterone. It is important to understand that these changes are normal and that every girl goes through them differently, and at different pace. Support from family and friends, and access to accurate information, can help girls navigate these changes and feel more comfortable with their developing bodies.
