- PCOS is a hormone imbalance that can cause irregular periods, unwanted hair, and acne.
- PCOS can be treated with diet, exercise, and medication.
- The tiny cysts on the ovaries are not harmful and don’t need to be removed.
Polycystic Ovary Syndrome (PCOS) is the most common reproductive endocrine disease among women of childbearing age. Although this condition has not received much publicity, it impacts many young women. In fact 5-10% of teens and young women have this diagnosis. The most common symptoms are irregular periods, weight gain, acne, and excess facial and body hair. The severity of the symptoms varies from girl to girl. Many teens are distressed with how the symptoms impact their life and self-esteem. Having an understanding of this disease, the etiology, current trends in medical treatment, and the important role of good nutrition and exercise will help you to support your daughter.
What is PCOS?
Polycystic ovary syndrome (PCOS) is a hormone imbalance that can cause irregular periods, unwanted hair growth, and acne. The name “Poly”, meaning “many”, and “Cystic”, meaning “cysts”, refer to the fact that those with PCOS may have enlarged ovaries that contain many very small cysts. These small cysts also called follicles develop in the ovary but the eggs are only rarely released. The outer wall of the ovaries thickens giving the ovary a polycystic appearance. These cysts are not cancerous and do not need to be surgically removed. It is not uncommon for girls with PCOS to have normal appearing ovaries but still have an imbalance in their hormone levels. Generally, symptoms of PCOS begin during the teenage years around the start of menstruation and can be mild or severe.
What are the signs of PCOS?
Young women with PCOS commonly have one or more signs.
Some of the most common signs include:
- Irregular periods – periods that come every few months, not at all, or too frequently
- Hirsutism – extra hair on the face or other body parts
- Weight gain and/or trouble losing weight, and in some cases, obesity
- Patches of dark skin on the back of the neck and other areas, called “acanthosis nigricans”
- Infertility or impaired fertility due to irregular periods or lack of ovulation
Other less common signs/symptoms may include:
- Hair thinning (on the top of the head)
- Skin tags under the armpits or neck area
- High total cholesterol and/or low HDL “good cholesterol”
- High blood pressure
- Pre-diabetes or in some cases, diabetes
How can I tell if my daughter has PCOS?
If your daughter has 2 or more of the above symptoms, she could have PCOS. There can be other reasons for these symptoms and therefore only a health care provider can tell for sure. If you or your daughter is distressed about the symptoms she is experiencing, you should make an appointment for her to be evaluated by her primary care provider. While she is waiting for her appointment, you can help her keep a log of her menstrual cycles and symptoms. She should bring the log with her when she meets with her provider. After an initial evaluation is completed, she may be referred to an adolescent gynecologist, adolescent medicine specialist, or an endocrinologist for further testing.
What causes PCOS?
PCOS is caused by an imbalance in the hormones secreted by the pituitary gland that in turn affects the ovaries. Many girls with PCOS also have higher than normal levels of insulin from the pancreas. PCOS usually happens when the luteinizing hormone (LH) levels or the insulin levels are too high, which then causes the ovaries to make extra amounts of testosterone.
For a more detailed explanation, take a look at the female reproductive anatomy image:
- The pituitary (pi-tu-i-tary) gland in the brain makes the hormones luteinizing (lu-tin-iz-ing) hormone (LH) and follicle (fall-i-call) stimulating hormone (FSH).
- After getting the signal from the hormones LH and FSH, the ovaries make estrogen (es-tro-gen) and progesterone (pro-ges-ter-own), the female sex hormones.
- All normal ovaries also make a little bit of the androgen testosterone (an-dro-gen tes-tos-ter-own), a male sex hormone. The pancreas (pang-cree-us) is an organ that makes the hormone insulin. High levels of insulin can also cause the ovaries to make more of the hormone testosterone.
Why does my daughter have irregular menstrual cycles?
Having PCOS means that your daughter’s ovaries are not getting the right (hormonal) signals from her pituitary gland. Without these signals she will not ovulate regularly. Her periods may be irregular or absent.
- The menstrual cycle starts when the brain sends LH and FSH to the ovaries. A big surge of LH is the signal that tells the ovaries to ovulate, or release a ripe egg.
- The egg travels down the fallopian tube and into the uterus. Progesterone from the ovary tells the lining of the uterus to thicken.
- If the egg isn’t fertilized, the lining of the uterus is shed and the menstrual period will start.
- After the menstrual period, the cycle begins all over again.
The diagrams show a normal menstrual cycle and a PCOS cycle. The PCOS cycle stops just before ovulation. As a result, girls with PCOS may ovulate occasionally or not at all so periods may be too close together or more usually, too far apart. Some girls may not get a period at all.
- With PCOS, LH levels are often high when the menstrual cycle starts. The levels of LH are also higher than FSH levels.
- Because the LH levels are already quite high, there is no surge. Without this LH surge, ovulation does not occur, and periods are irregular.
What types of tests will my daughter need to have?
It’s likely that your daughter’s health care provider will ask her a lot of questions about her menstrual cycle and her general health and then do a complete physical examination. She most likely will need to have a blood test to check her hormone levels, blood sugar, and cholesterol. An ultrasound test to check her uterus and ovaries may also be ordered.
Does PCOS mean that my daughter has cysts on her ovaries?
The term “polycystic ovaries” means that there are many tiny cysts, or bumps, inside of her ovaries. Some young women with PCOS have these cysts; others only have a few. Even if your daughter has a lot of them, they are not harmful and they do not need to be removed.
Why does my daughter have acne and/or extra hair on her body?
Acne and extra hair on the face and body can happen if your daughter’s body is making too much testosterone. All women make testosterone, but with PCOS, the ovaries make more testosterone than they are supposed to. Skin cells and hair follicles are extremely sensitive to the slight increases in testosterone found in young women with PCOS, which contributes to excess hair growth in areas such as the upper lip, chin, sideburn area, chest, and stomach.
What causes the patches of dark skin that my daughter has?
Many adolescents with PCOS have higher levels of the hormone, insulin, in their blood. Higher levels of insulin can sometimes cause patches of darkened skin on the back of the neck, under the arms, and in the groin area. This condition is called acanthosis nigricans.
Will PCOS affect my daughter’s fertility?
Women with PCOS have a normal uterus and healthy eggs. Many women with PCOS have trouble getting pregnant (because they don’t ovulate regularly), but some women have no trouble at all. There are new options available including medications that aim to lower insulin levels, which stimulate ovulation. Girls with PCOS should talk to their primary care provider even if they are not interested in becoming pregnant right away. There are several medical therapies that are available to enhance fertility. Your daughter should be reassured by her health care provider and you that good nutrition, weight control if she’s overweight, and reducing insulin and glucose levels may induce normal ovulation and, in turn, improve her fertility outcome. Medical treatment continues to get better.
Is there anything girls with PCOS can personally do to help themselves?
While there is no miracle-cure for PCOS, it can be treated. A healthy lifestyle that includes nutritious foods and daily exercise can have a profound and positive effect on the endocrine system, particularly in cases when a young woman is overweight or obese. Studies have shown that losing even 5% of body weight in overweight and obese women with PCOS can eliminate some of the symptoms associated with this disorder. Although there are some young women with PCOS who are either underweight or average weight, some find that they gain weight easily, so for them daily exercise is a way to be proactive about their health.
What are the treatment options for girls with PCOS?
The most common form of treatment for PCOS is the birth control pill; however, other kinds of hormonal therapy may include the “vaginal ring” and “the patch”. Even if a young woman is not sexually active, her health care provider may prescribe birth control pills because they contain the hormones that her body needs to treat her PCOS. The birth control pill may be prescribed continuously (one pill is taken every day without any breaks) or cyclically (1 hormone pill is taken for 21 days then a placebo or “remember” pill with no hormones is taken for 7 days).
The birth control pill works by:
- Correcting the hormone imbalance
- Lowering the level of testosterone (which will improve acne and lessen hair growth)
- Regulating menstrual periods
- Lowering the risk of endometrial cancer (which is slightly higher in young women who don’t ovulate regularly)
- Preventing an unplanned pregnancy, if she is sexually active
Are there any other medications used to treat PCOS?
Another medicine which helps the body lower the insulin level is called Metformin. It is particularly helpful in girls who have high levels of insulin or have pre-diabetes or diabetes. It is necessary for a young woman to have a blood test to check her kidney and liver function before taking this medication. Since this medicine isn’t appropriate for everyone, it is important to talk with your daughter’s health care provider to see whether this medicine is right for her. Because there is a possibility that ovulation can occur while taking this medication, your daughter will be counseled on the importance of using birth control if she is sexually active. Additionally, if your daughter is prescribed Metformin, she will be advised to avoid alcohol. Some young women are treated with both Metformin and birth control pills at the same time.
What about treating excess hair growth?
Treatment is individually based. Options may include bleaching, waxing, depilatories, Spironolactone (spi-ro-no-lac-tone), electrolysis, and laser treatment. Spironolactone is a prescription medicine that can decrease hair growth and make hair lighter and finer. However, it can take up to 6-8 months to see an improvement.
Are there any special treatments for acne associated with PCOS?
There are various ways to treat acne in general, including the birth control pill, topical creams, oral antibiotics, and other medications. These treatments are not necessarily specific to PCOS. Studies have shown that when insulin and glucose levels are controlled and ovulation resumes, acne and other skin conditions may improve greatly.
What about weight loss plans?
Losing excess weight when someone is overweight may reduce some of the symptoms of PCOS. It is often beneficial for a young woman with PCOS to talk to her health care provider or nutritionist about healthy ways to lose weight and increase exercise. Following a nutrition plan that helps manage insulin levels may help girls with PCOS manage their weight too. It also keeps the heart healthy and lowers a girl’s risk of developing diabetes.
If your daughter has PCOS, encourage her to:
- Choose nutritious, high-fiber carbohydrates instead of sugary carbohydrates
- Balance carbohydrates with protein and healthy fats
- Eat small meals and healthy snacks throughout the day instead of large meals
- Exercise regularly to help manage insulin levels and weight
Is it normal for a young woman with PCOS to feel worried about her health?
When a teen or a young woman is first diagnosed with PCOS, she often feels confused. It is a difficult diagnosis to understand and the symptoms can be distressing. Girls may also feel frustrated and/or sad if they are having a hard time losing weight, dealing with acne, excess body hair, and menstrual irregularities. When a health care provider takes the time to explain what PCOS is and offers treatment options, a young woman may feel relieved that at last there is an explanation and treatment for the problems she has been suffering with. Having a diagnosis without an easy cure can be difficult. However, it is important for girls with PCOS to know they are not alone. Finding a doctor who knows a lot about PCOS and who they feel comfortable talking to is very important. Keeping a positive attitude and working on a healthy lifestyle even when results seem to take a long time is very important too! Many girls with PCOS tell us that talking with a counselor about their concerns can be very helpful. The Center for Young Women’s Health offers a free and confidential monthly (internet) chat for girls and young women with PCOS that is moderated by a nurse and registered dietitian.
Is there anything else I should know to help my daughter?
It’s important that girls with PCOS follow-up regularly with their doctor and take their medication. The prescribed treatment will regulate your daughter’s periods and lessen her chance of getting diabetes and other problems. Because young women with PCOS have a slightly higher chance of developing diabetes, her doctor may suggest that she have her blood sugar tested once a year or have a glucose challenge test (oral glucose tolerance test) every few years. Girls who are on hormonal pills to treat PCOS and who smoke should receive counseling on smoking cessation.
Supporting your daughter in her efforts to make even small changes in nutrition and physical exercise can help her to take charge of her health. Understanding and learning more about PCOS will help you to be supportive to your daughter’s emotional needs. Resources such as educational websites and monitored internet chats may provide additional support.
