Cecily never really worried that her periods weren't regular
because, like many girls, she assumed her monthly cycle would take
time to settle down. But then Cecily's periods stopped for
several months, so she went to see her doctor.
The doctor noticed that Cecily's acne had worsened and that
she had gained a lot of weight since her last appointment. She said
she wanted to check Cecily for a condition called
polycysticovary sydrome (PCOS)
.
What Is Polycystic Ovary Syndrome?
Polycystic (pronounced: pah-lee-
sis
-tik) ovary syndrome is a common health problem that affects
teenage girls and young women. Although no one really knows what
causes PCOS, it seems to be related to an imbalance in a girl's
hormones.
Both girls and guys produce sex hormones, but in different
amounts. In girls, the ovaries produce the hormones
estrogen
and
progesterone
, and also
androgens
. These hormones regulate a girl's menstrual cycle and
ovulation. Even though androgens are sometimes referred to as
"male hormones," every female produces them.
In girls with PCOS, the ovaries produce higher than normal
amounts of androgens, and this can interfere with egg development
and release. Some of the eggs develop into
cysts
, which are little sacs filled with liquid. Instead of being
released during ovulation, as an egg is during a normal menstrual
cycle, the cysts build up in the ovaries and may become enlarged.
Because girls with PCOS are not ovulating or releasing an egg each
month, it's common for them to have irregular or missed
periods.
Although PCOS (which used to be called Stein-Leventhal syndrome)
was first recognized in the 1930s, doctors can't say for sure
what causes it. Research has suggested that PCOS may be related to
increased insulin production in the body. Women with PCOS may
produce too much insulin, which signals their ovaries to release
extra male hormones. PCOS seems to run in families, too, so if
someone on your mom's or dad's side of the family has it,
you might be more likely to develop it.
If PCOS is not treated properly, it can put a girl at risk for
lots of problems. Girls with PCOS are more likely to have
infertility, excessive hair growth, acne, obesity, diabetes, heart
disease, high blood pressure, abnormal bleeding from the uterus,
and cancer.
The good news is that, although there's no cure for PCOS, it
can be treated. The most important step is diagnosing the
condition, because getting treatment for PCOS reduces a girl's
chances of having serious side effects.
What Are the Signs and Symptoms?
A key sign of PCOS is irregular or missed periods because the
effects of the condition on the ovaries can make a girl stop
ovulating. However, because it can take up to 2 years after her
first period for a girl's menstrual cycle to become regular,
missed periods may not be a reliable sign of PCOS in teen girls.
Imbalanced hormone levels can cause changes in a girl's entire
body, not just her ovaries.
So doctors also look for these other signs that might indicate
PCOS:
- very heavy periods or periods that come more than once a
month
- weight gain, obesity, or difficulty maintaining a normal
weight, especially when the extra weight is concentrated around
the waist
- a condition called
hirsutism
(pronounced:
her
-suh-tiz-um), where a girl grows extra hair on her face, chest,
abdomen, nipple area, or back (a little of this is normal for
most girls, though)
- thinning hair on the head (doctors call this alopecia)
- acne and clogged pores
- darkened, thickened skin around the neck, armpits, or breasts
(this is called
acanthosis nigricans
)
- high blood pressure, high cholesterol, or diabetes mellitus
(high levels of sugar in your blood)
Girls who show certain signs of puberty early - such as girls
who develop underarm or pubic hair before the age of 8 - may be at
greater risk of having PCOS later on.
How Is Polycystic Ovary Syndrome Diagnosed?
If you've taken your concerns about your body to your
doctor, you're on the right track. Your doctor may refer you to
a gynecologist or an endocrinologist for a diagnosis.
The gynecologist or endocrinologist will ask you about any
concerns and symptoms you have, your past health, your family's
health, any medications you're taking, any allergies you may
have, and other issues. He or she will also ask you lots of
questions specifically about your period and its regularity. This
is called the
medical history
.
In addition to your medical history, your doctor will do a
physical examination
, which includes checking your weight, and checking especially for
physical signs such as acne, hair growth, and darkened skin. If you
are sexually active, the doctor may perform a
gynecologic examination
to rule out other possible causes of your symptoms, but this is not
always necessary for diagnosis.
A doctor may also perform blood tests to diagnose PCOS or other
conditions, such as thyroid or other ovarian or gland problems.
Blood tests allow doctors to measure androgen, insulin, and other
hormone levels. The results of these tests can help doctors to
determine the type of treatment a girl will receive. Your doctor
may also order another test, called an ultrasound, to look at your
ovaries and to determine if you have cysts or other abnormalities
of the ovaries. Because cysts are not always visible, this test is
not always used.
Early diagnosis and treatment for PCOS are important because the
condition can put girls at risk for long-term problems. Getting
treated for PCOS is a good idea if you want to have a baby someday
- PCOS often causes infertility if it's not treated. But when
PCOS is treated properly, many women with the condition have
healthy babies.
Also, many girls with PCOS can get pregnant. If you are sexually
active and do not want to become pregnant, be sure to use condoms
every time you have sex even if you have PCOS. This is important
even if you are not being treated for PCOS.
How Is It Treated?
Although there's no cure for PCOS, there are several ways
that the condition can be treated and managed.
If a girl is overweight or obese, a doctor will recommend that
she lose weight. Weight loss can be very effective in lessening
many of the health conditions associated with PCOS, such as high
blood pressure and diabetes. Sometimes weight loss alone can
restore hormone levels to normal, causing many of the symptoms to
disappear or become less severe. Your doctor or a registered
dietitian can look at your food intake and your exercise and
activity to tailor a weight-loss program for you. Exercise is a
great way to help combat the weight gain that often accompanies
PCOS as well as a way to reduce bloating, another symptom girls
with PCOS sometimes experience.
Sometimes doctors prescribe medications to treat PCOS. A doctor
might first have a girl try birth control pills or another hormone
pill called progesterone to help reduce the androgen levels in her
body and regulate her menstrual cycle. These medicines may help
control acne and excessive hair growth in some girls, but they
don't work for everyone.
Other medications used to treat PCOS include
antiandrogens
, which counter the effects of excess androgens on a girl's
body. Antiandrogens can help clear up skin and hair growth problems
in girls with PCOS. Another medication, metformin, which is used to
treat diabetes, can lower insulin levels. In some girls with PCOS,
it can help control ovulation and androgen levels. This can make a
girl's menstrual cycles more regular. Some girls and women
treated with metformin have also experienced weight loss and
lowering of high blood pressure.
Coping With Polycystic Ovary Syndrome
Having PCOS can be hard on a girl's self-esteem because some
of the symptoms, such as skin and hair problems and weight gain,
are so noticeable. Fortunately, there are things you can do to
reduce the physical symptoms - and take care of the emotional side
of living with PCOS.
Although the medications used to treat PCOS will slow down or
stop excessive hair growth for many girls, there are lots of
different types of products available to help a girl get rid of
hair where she doesn't want it. Depilatory creams can gently
remove facial hair on the upper lip or chin. Be sure to follow the
instructions carefully so you don't develop a rash or allergic
reaction.
Tweezing and waxing are other things you can do at home to
manage hair growth. A girl can also visit a dermatologist (a doctor
who specializes in skin problems) or qualified hair removal
specialist for electrolysis and laser surgery treatments. These
procedures offer longer term removal of unwanted hair, but they are
more expensive.
If you have severe acne as a symptom of PCOS, it may improve if
part of your treatment includes birth control pills or
antiandrogens. If it doesn't, your doctor may refer you to a
dermatologist for further acne treatment. A dermatologist may also
be able to recommend medications to help reduce skin darkening or
discoloration, and to prevent hair growth.
Some girls with PCOS may become depressed, in which case it may
help to talk to a therapist or other mental health professional.
Talking with other teens and women with PCOS is a great way to
share information about treatment and get support. Your doctor may
be able to recommend a local support group.
If you can't find a local group, the Polycystic Ovarian
Syndrome Association offers a "Big Cyster" program for
teen girls as well as online message boards. If you join,
you'll be hooked up with other women or teen girls with PCOS to
whom you can turn for advice, support, or just a listening ear.
