Puberty: Some Important things you must know
Puberty is the name for the time when your body
goes through changes and you begin to go from being a child to an adult. Your
hormone levels will change, you will develop breasts, grow taller, and start
your menstrual periods. Puberty usually starts between 8 and 13 years of age.
During puberty, the same changes happen to all girls, but the time they happen
is different for every girl. These changes are all part of becoming a woman.
They are something to celebrate!
When the time is right, your body sends a signal
(FSH, LH) from the pituitary gland in your brain to your ovaries for puberty to
begin.
Breast development. Your breasts
will start to grow. Your breasts will start as breast “buds”, small mounds beneath the nipple and areola. (The areola
is the dark area surrounding your nipple.) One breast may start growing before
the other, sometimes even 6 months before the other. In the beginning, they may hurt sometimes and be
tender when they are touched. But this will go away as your breasts become
rounder and fuller. The nipple and areola also darken. Many girls have breasts
that develop unevenly; one breast may be bigger than the other. This is
perfectly normal. Many women have one breast that is slightly larger than the
other, but the difference in breast size usually decreases as your breasts
develop. Young women may have different breast sizes because of differences in
families, hormones, and weight. Rapid development of breasts can lead to
spoke-like stretch marks, but these will lighten with time. Towards the end of
puberty, you may also grow a small amount of hair around your areola.
You may need to start thinking about wearing a bra
to support your breasts. Talk to your mother, an older sister, or an adult that
you feel comfortable with about buying some bras.

below show the 5 stages of breast development:
Pubic and underarm hair. You will
start to grow hair around your pubic area (around your vagina) and under your
arms. This usually happens after you start to develop breasts, but for many
girls, pubic hair starts first. You will probably get pubic hair before you get
underarm hair. Underarm hair usually comes near the end of puberty. At first,
you will probably just have a few fine hairs in your pubic area and under your
arms. Late in puberty, the hair will become thicker and curlier. Some girls
decide to shave the hair under their arms. There are no health reasons to do
so, but some girls simply prefer not to have underarm hair. It is up to you if
you want to shave. Talk to your mom or another adult that you feel comfortable
talking to about this.

Growth spurt and body shape change.
Most girls have a growth spurt the year before they get their menstrual period.
Your feet and hands will usually be the first parts to grow, and then the rest
of your body will follow. After you get your first period, you will grow more
slowly. But you will probably grow about another 1 or 2 inches after your first
period. During puberty, your hips will get wider as your waist gets smaller.
You will develop a healthy, curvy shape. Talk to your health care provider if
you are not growing and changing by age 13. It's important to get check-ups
during puberty to make sure that your height and weight are normal.
Vaginal discharge. Most girls
notice a yellow or white stain in the crotch of their underpants as they go
through puberty. This is a normal fluid that helps clean and moisten your
vagina. However, if you have itching, odor, or irritation around your vagina,
this could mean that you have an infection. If you have any of these symptoms,
talk to your health care provider. You will usually get your period a year after
you first have discharge from your vagina.
Skin. Your skin may get oilier.
You may get some pimples and acne. This is because of more hormones and oil
glands that become more active during puberty. You should be washing your skin
at least once daily with soap and warm water. Don't scrub too hard because this
can irritate your skin and cause even more acne. Wash your hair regularly and
keep your face and hands clean. You can treat acne with medications that you
can buy in a drugstore, or get from your primary care clinician or a
dermatologist (a doctor that treats skin problems) if the problem is more
serious. Birth control pills that you take by mouth often make acne better.
Sweat/Perspiration. Your sweat
glands will become more active during puberty. This can cause perspiration
odor. This is a good time to go shopping for deodorant, to help fight the odor.
Menstruation. You will also start
getting your monthly period. Most girls start getting their periods about 2 and
a half years after they first start developing breasts, some girls may start
just 1 year after breast development, and other girls often start 3-4 years
after breast development. Most girls have their first period between the ages
of 12 and 13, but some girls start as early as age 9, and others as late as 15
or 16.
