-> The pituitary gland in the brain makes the hormones luteinizing hormone (LH) and follicle stimulating hormone (FSH).
-> After getting the signal from the hormones LH and FSH, the ovaries make estrogen and progesterone, the female sex hormones. All normal ovaries also make a small amount of the androgen, testosterone, but the ovaries of a girl with PCOS make too much testosterone.
-> High levels of insulin, secreted by the pancreas, can also cause the ovaries to make more of the testosterone hormone.
Why do young women with PCOS have irregular menstrual cycles?
Having PCOS means that a young woman’s ovaries are not getting the right hormonal signals from the pituitary gland. Without these signals they will not ovulate regularly. Their periods may be irregular or absent.
-> Normally 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 PCOS cycle shows where the menstrual 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, the surge that sets off the chain reaction causing ovulation does not happen. Without this LH surge, ovulation does not occur and periods are irregular.
What types of tests will a doctor do to diagnose PCOS?
Generally a young woman’s doctor 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 the uterus and ovaries may also be obtained.
Why do young women with PCOS get acne and/or extra hair on their body?
Acne and extra hair on the face and body can happen if a young woman’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 in young women with PCOS?
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 a young woman’s fertility?
Women with PCOS have a normal uterus and healthy eggs. Many women with PCOS have trouble getting pregnant, 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. Their doctor will explain the current medical therapies that are available. Reassure the young woman that good nutrition, weight control in girls who are overweight, and reducing insulin and glucose levels may induce normal ovulation, improving her fertility outcome. Remind her that medical treatment is constantly moving forward.
Is there anything girls with PCOS can personally do to help themselves?
While there is no 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 five percent 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. The doctor 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 or cyclically. The birth control pill works by:
1) Correcting the hormone imbalance
2) Lowering the level of testosterone which will improve acne and lessen hair growth
3) Regulating her menstrual periods
4) Lowering the risk of endometrial cancer (which is higher in young women who don’t ovulate regularly)
Are there any other medications used to treat PCOS?
Yes. Metformin is a relatively new medicine which helps the body lower the insulin level. 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 her kidney and liver function checked before taking this medication. Since this medicine isn’t appropriate for everyone, it is important to encourage a young woman to ask her doctor whether this medicine is right for her. Because a young woman may ovulate while on this medication, she will also need to use birth control if she is sexually active. Alcohol should be avoided when taking metformin. Some young women may be 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, which is a prescription anti-hair growth medication, electrolysis, and laser treatment. A young woman may require help finding a local salon that provides high quality, cost-effective services that will help her to choose the right option.
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 doctor or nutritionist about healthy ways to lose weight and increase her 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. Encourage the young woman with PCOS to:
1) Choose nutritious, high-fiber carbohydrates instead of sugary carbohydrates.
2) Balance carbohydrates with protein and healthy fats.
3) Eat small meals and snacks throughout the day instead of large meals.
4) Exercise regularly to help manage insulin levels and her weight.
Is it normal for a young woman with PCOS to feel concerned about her health?
When a teen or a young woman is initially diagnosed with PCOS, she often feels confused. It is a difficult diagnosis to comprehend and the symptoms are 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 doctor 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!
Is there anything else I should know?
It is important that girls with PCOS follow-up regularly with their doctor and take their medication. The prescribed treatment will regulate her 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 every few years. Girls who are on hormonal pills to treat PCOS and who smoke should receive counseling on smoking cessation.
