olycystic ovary syndrome
(PCOS) is a disorder that
occurs when levels of certain
hormones are abnormal. Women
with PCOS may have irregular or
no menstrual periods, infertility,
and excess hair growth. PCOS
also can cause long-term health
problems in women, but it can be
treated. This pamphlet will
explain:
- What is PCOS
- How it is diagnosed
- How PCOS can be treated
|
|
With proper treatment,
PCOS can be managed and
your symptoms can be
relieved. |
Signs and Symptoms
Women with PCOS have a history of irregular menstrual
bleeding and often have difficulty getting
pregnant. They also may have unwanted hair
growth in places such as on the face (mainly on the
upper lip and chin), between their breasts, in the
lower part of the abdomen, and on the inner thighs.
In severe cases, PCOS can lead to balding, lowering
of the voice, and bigger muscles.
Many women with PCOS produce too much
insulin or the insulin they produce does not work
as it should. This is one reason why women with
PCOS tend to gain weight or have a hard time losing
weight. They also have an increased risk of diabetes
(a condition in which the levels of sugar in
the blood are too high), high blood pressure, and
heart disease.
Causes
Each month an egg matures in a woman's ovary.
The egg is surrounded by a sac called a follicle. The
cells of the follicle first produce the hormone estrogen.
The egg is then released (ovulation), and the
follicle cells begin to produce progesterone as well
as estrogen.
Women with PCOS produce an excess amount
of male sex hormones called androgens. All
women produce a certain amount of these hormones.
When too much is produced, it can prevent
ovulation. This can result in infertility. Too much
androgen also can result in excess hair growth and
irregular bleeding.
Diagnosis
Women who are not ovulating and have signs of
androgen excess are considered to have PCOS. The
diagnosis is based on a medical history, physical
exam, and lab tests. Your doctor will ask you about
your health, your menstrual cycle, and any unwanted
hair growth. During a complete physical exam
your doctor will look for signs of androgen excess
and measure your blood pressure. He or she also may
measure your waist, hips, height, and weight. Blood
tests may be done to look for signs of diabetes or to
check the levels of hormones or other substances.
An ultrasound exam may be done to look for
small cysts on the ovary. These cysts often occur
with PCOS.
Treatment
PCOS is a lifelong condition, but it can be treated in
a number of ways. Treatment depends on the symptoms
and whether a woman wants to become pregnant.
Long-term treatment may be needed to help
prevent endometrial cancer, diabetes, and heart
disease.
Lifestyle Changes
Daily exercise improves the body's use of insulin and
can help relieve symptoms of PCOS. Many of the
symptoms of PCOS may be improved by daily exercise
for at least 30 minutes a day.
In some women with PCOS, weight loss will
lower insulin levels enough to allow ovulation to
begin. It also may help slow new hair growth. Talk
to your doctor or a nutritionist for advice on how
to lose weight.
Medication
Your doctor may prescribe progesterone (or other
hormones) or birth control pills to bring on regular
menstrual bleeding. Women who wish to become
pregnant may be given medications to help them
ovulate. Some women with PCOS will be prescribed
medication to lower their insulin levels.
Your doctor also may prescribe birth control
pills and other medications to help slow the
growth of new body hair. It may take a number of
months for you to notice any results. These medications
likely will not remove hair that is already
there. Unwanted hair can be removed by shaving,
electrolysis, or other hair removal methods.
If needed, other medications may be used to
treat diabetes, high blood pressure, and high cholesterol
levels.
Finally...
With proper treatment, PCOS can be managed and
your symptoms can be relieved. You should have
long-term health care to look for disorders that may
arise. If you have PCOS, changes in your lifestyle
will improve your health.
