(LET’S KNOW MORE ABOUT MENSTRUATION)
Puberty and Periods
Menstruation
(a period) is a major stage of puberty in girls. It's one of the many physical
signs that a girl is turning into a woman.
Menstruation
can be confusing, just like a lot of the other changes that come with
puberty. Some girls can't wait to start their periods. Others may feel afraid
or anxious. Many girls (and most guys!) don't have a complete understanding of
a woman's reproductive system or what actually happens during the menstrual
cycle. That can make the process seem even more mysterious.
Girls
usually start to go through puberty between the ages of 8 and 13. Their
bodies and minds change in many ways. Hormones kick off changes
like growth and breast development. About 2 to 2½ years after a girl's
breasts begin to develop, she usually gets her first menstrual period.
About 6
months or so before getting her first period, a girl might notice an increased
amount of clear vaginal discharge. This discharge is common. There's no need
for a girl to worry about discharge unless it has a strong odor or causes
itchiness.
When a
girl first gets her period, doctors call it menarche. Menarche doesn't happen until all the parts of a girl's
reproductive system have matured and are working together
When a
girl starts puberty, the pituitary gland releases hormones that stimulate the
ovaries to produce other hormones called estrogen and progesterone. These
hormones have many effects on a girl's body, including physical maturation, growth,
and emotions.
About
once a month, a tiny egg leaves one of the ovaries — a process called ovulation
— and travels down one of the fallopian tubes toward the uterus. In the days
before ovulation, the hormone estrogen stimulates the uterus to build up its
lining with extra blood and tissue, making the walls of the uterus thick and
cushioned. This happens to prepare the uterus for pregnancy: If the egg is
fertilized by a sperm cell, it travels to the uterus and attaches to the
cushiony wall of the uterus, where it slowly develops into a baby.
If the
egg isn't fertilized, though — which is the case during most of a woman's
monthly cycles — it doesn't attach to the wall of the uterus. When this
happens, the uterus sheds the extra tissue lining. The blood, tissue, and
unfertilized egg leave the uterus, going through the vagina on the way out of
the body. This is a menstrual period.
This
cycle happens almost every month for several more decades (except, of course,
when a female is pregnant) until a woman reaches menopause and no longer
releases eggs from her ovaries.
How
Often Does a Girl Get Her Period?
Just as
some girls begin puberty earlier or later than others, the same applies to
periods. Some girls may start menstruating as early as age 10, but others may
not get their first period until they are 15 years old.
The
amount of time between a girl's periods is called her menstrual cycle (the
cycle is counted from the start of one period to the start of the next). Some
girls will find that their menstrual cycle lasts 28 days, whereas others might
have a 24-day cycle, a 30-day cycle, or even longer. Following menarche,
menstrual cycles last 21–45 days. After a couple of years, cycles shorten to an
adult length of 21–34 days.
Irregular
periods are common in girls who are just beginning to menstruate. It may take
the body a while to sort out all the changes going on, so a girl may have a
28-day cycle for 2 months, then miss a month, for example. Usually, after a
year or two, the menstrual cycle will become more regular. Some women continue
to have irregular periods into adulthood, though.
As a
girl gets older and her periods settle down — or she gets more used to her own
unique cycle — she will probably find that she can predict when her period will
come. In the meantime, it's a good idea to keep track of your menstrual cycle
with a calendar.
How Long and How Much?
The
amount of time that a girl has her period also can vary. Some girls have
periods that last just 2 or 3 days. Other girls may have periods that last 7
days. The menstrual flow — meaning how much blood comes out of the vagina — can
vary from girl to girl, too.
Some girls may worry that
they're losing too much blood. It can be a shock to see all that blood, but
it's unlikely that a girl will lose too much, unless she has a medical
condition like von willebranch
disease. Though it may look like a
lot, the average amount of blood is only about 2 tablespoons (30 milliliters)
for an entire period. Most girls change pads 3 to 6 times a day. They'll
probably change pads more often when their period is heaviest, usually at the
start of the period.
You may
be worried about whether your period is normal in other ways. This is normal
when a girl first gets her period and isn't sure what to expect. Your doctor or
nurse can answer any questions about your period. Here are some times it's
especially important to talk to a doctor or nurse if:
·
your period lasts longer than a week
·
your blood soaks thorough more than one pad every 1–2 hours
·
you go longer than 3 months between periods
·
you have bleeding in between periods
·
you have an unusual amount of pain before or during your period
·
your periods were regular then became irregular
Cramps
Lots
of girls notice body or mood changes around the time of their periods.
Menstrual cramps are pretty common. More than half of all women who get
periods say they have cramps during the first few days. Doctors think that
cramps are caused by a chemical called prostaglandin that causes the
muscles of the uterus to contract.
Cramps
can be dull and achy or sharp and intense. Sometimes a woman feels cramps in
her back as well as her tummy area. Some girls find their cramps
aren't as bad as they get older. Sometimes they go away completely.
Many
girls and women find that over-the-counter pain medicine (like acetaminophen or
ibuprofen) can help cramps. So can taking a warm bath or putting a warm
heating pad on the lower abdomen. Exercising regularly throughout the
monthly cycle may help lessen cramps, too. If these things don't help, ask your
doctor for advice.
PMS and
Pimples
Some girls and women find that they feel sad or easily irritated
during the few days or week before their periods. Others may get angry more
quickly than normal or cry more than usual. Some girls crave certain foods.
These types of emotional changes may be the result of premenstrual syndrome (PMS).
PMS is
related to changes in the body's hormones. As hormone levels rise and fall
during a woman's menstrual cycle, they can affect the way she feels, both
emotionally and physically. Some girls, in addition to feeling more intense
emotions than they usually do, notice physical changes along with their periods
— some feel bloated or puffy because of water retention, others notice swollen
and sore breasts, and some get headaches.
PMS
usually goes away soon after a period begins, but it can come back month after
month. Eating right, getting enough sleep, and exercising may help relieve some
of the symptoms of PMS. Talk to your doctor if you are concerned about your
premenstrual symptoms.
It's
also not uncommon for girls to have an acne flare-up during certain times of
their cycle; again, this is due to hormones. Fortunately, the pimples
associated with periods tend to become less of a problem as girls get older.
