==What causes Polycystic Ovary Syndrome?==
==What causes Polycystic ovary syndrome?==
The cause of PCOS is unknown. Most researchers think that more than one factor could play a role in developing PCOS. Genes are thought to be one factor. Women with PCOS tend to have a mother or sister with PCOS. Researchers also think insulin could be linked to PCOS. Insulin is a hormone that controls the change of sugar, starches, and other food into energy for the body to use or store. For many women with PCOS, their bodies have problems using insulin so that too much insulin is in the body. Excess insulin appears to increase production of androgen. This hormone is made in fat cells, the ovaries, and the adrenal gland. Levels of androgen that are higher than normal can lead to acne, excessive hair growth, weight gain, and problems with ovulation.

'''What causes the symptoms of PCOS?'''The ovaries are two small organs, one on each side of a woman's uterus. A woman's ovaries have follicles, which are tiny sacs filled with liquid that hold the eggs. These sacs also are called cysts. Each month about 20 eggs start to mature, but usually only one matures fully. As this one egg grows, the follicle accumulates fluid in it. When that egg matures, the follicle breaks open to release it. The egg then travels through the fallopian tube for fertilization. When the single egg leaves the follicle, ovulation takes place.

When the single egg leaves the [[follicle]], [[ovulation]] takes place.


In women with PCOS, the ovary doesn't make all of the hormones it needs for any of the eggs to fully mature. Follicles may start to grow and build up fluid. But no one follicle becomes large enough. Instead, some follicles may remain as cysts. Since no follicle becomes large enough and no egg matures or is released, ovulation does not occur and the hormone progesterone is not made. Without progesterone, a woman's menstrual cycle is irregular or absent. Plus, the cysts make male hormones, which also prevent ovulation.

==Who is at risk for Polycystic Ovary Syndrome?==
==Who is at highest risk?==
About one in ten women of childbearing age has PCOS, and it can occur in girls as young as 11 years old. In addition, most researchers think that PCOS runs in families. Women with PCOS tend to have a mother or sister with PCOS.

==Diagnosis==
==When to seek urgent medical care?==
There is no single test to diagnose PCOS. Your doctor will take a '''medical history''', perform a '''physical exam''', and possibly take some tests to rule out other causes of your symptoms. During the physical exam the doctor will want to measure your blood pressure, body mass index (BMI), and waist size. He or she also will check out the areas of increased hair growth, so try to allow the natural hair growth for a few days before the visit. Your doctor might want to do a '''pelvic exam''' to see if your ovaries are enlarged or swollen by the increased number of small cysts. A '''vaginal ultrasound''' also might be used to examine the ovaries for cysts and check out the endometrium, the lining of the uterus. The uterine lining may become thicker if your periods are not regular. You also might have blood taken to check your hormone levels and to measure glucose (sugar) levels.
Talk with your doctor if you have irregular, scant or no [[menstrual period]]s, are [[overweight]], and have [[acne]] or excess facial hair growth.  


==When to seek urgent medical care==
It appears to be higher rates of miscarriage, [[gestational diabetes]], pregnancy-induced high blood pressure (pre-eclampsia), and premature delivery in women with PCOS. Researchers are studying how the diabetes medicine metformin can prevent or reduce the chances of having these problems while pregnant.

Researchers are studying how the diabetes medicine metformin can prevent or reduce the chances of having these problems while pregnant.  
Women with PCOS have greater chances of developing several serious, life-threatening diseases, including [[type 2 diabetes]], [[cardiovascular disease]] (CVD), and [[cancer]]. Recent studies found that:
*More than 50 percent of women with PCOS will have [[diabetes]] or pre-diabetes (impaired glucose tolerance) before the age of 40.
*Women with PCOS have a four to seven times higher risk of [[heart attack]] than women of the same age without PCOS.
*Women with PCOS are at greater risk of having [[hypertension]].
*Women with PCOS have high levels of LDL (bad) cholesterol and low levels of HDL (good) cholesterol.
The chance of getting endometrial cancer is another concern for women with PCOS. Irregular menstrual periods and the absence of [[ovulation]] cause women to produce the hormone estrogen, but not the hormone [[progesterone]]. Progesterone causes the endometrium to shed its lining each month as a menstrual period. Without progesterone, the endometrium becomes thick, which can cause heavy [[bleeding]] or irregular bleeding. Over time, this can lead to endometrial hyperplasia, when the lining grows too much, and cancer.

Because there is no cure for PCOS, it needs to be managed to prevent problems. Treatment goals are based on your symptoms, whether or not you want to become pregnant, and lowering your chances of getting heart disease and diabetes. Many women will need a combination of treatments to meet these goals. Some treatments for PCOS include:

===Birth Control Pills===
For women who don't want to become pregnant, birth control pills can control menstrual cycles, reduce male hormone levels, and help to clear acne. However, the menstrual cycle will become abnormal again if the pill is stopped. Women may also think about taking a pill that only has progesterone to control the menstrual cycle and reduce the risk of endometrial cancer. But progesterone alone does not help reduce acne and hair growth.

The medicine metformin is used to treat type 2 diabetes. It also has been found to help with PCOS symptoms, although it is not FDA-approved for this use. Metformin affects the way insulin controls blood glucose (sugar) and lowers testosterone production. Abnormal hair growth will slow down, and ovulation may return after a few months of use. Recent research has shown metformin to have other positive effects, such as decreased body mass and improved cholesterol levels.

===Fertility Medications===
Lack of ovulation is usually the reason for fertility problems in women with PCOS. Several medications that stimulate ovulation can help women with PCOS become pregnant. Even so, other reasons for infertility in both the woman and man should be ruled out before fertility medications are used. Also, there is an increased risk for multiple births (twins, triplets) with fertility medications. Another option is in vitro fertilization (IVF). IVF offers the best chance of becoming pregnant in any one cycle and gives doctors better control over the chance of multiple births. But, IVF is very costly.

===Surgery===
===[[Surgery]]===
"Ovarian drilling" is a surgery that brings on ovulation. It is sometimes used when a woman does not respond to fertility medicines. The doctor makes a very small cut above or below the navel and inserts a small tool that acts like a telescope into the abdomen. This is called laparoscopy. The doctor then punctures the ovary with a small needle carrying an electric current to destroy a small portion of the ovary. This procedure carries a risk of developing scar tissue on the ovary. This surgery can lower male hormone levels and help with ovulation. But these effects may only last a few months. This treatment doesn't help with loss of scalp hair and increased hair growth on other parts of the body.

Keeping a healthy weight by eating healthy foods and exercising is another way women can help manage PCOS. Many women with PCOS are overweight or obese. Eat fewer processed foods and foods with added sugars and more whole-grain products, fruits, vegetables, and lean meats to help lower blood sugar (glucose) levels, improve the body's use of insulin, and normalize hormone levels in your body. Even a 10 percent loss in body weight can restore a normal period and make a woman's cycle more regular.

The National Institue of Child Health and Human Development’s Division of Epidemiology, Statistics, and Prevention Research (DESPR) is exploring early signs of PCOS in teenage girls. Some research suggests that certain signs of PCOS are present at or before puberty. The DESPR research study is examining the relationships among ovarian shape and size, obesity around the waist, and biomarkers of insulin resistance as signs of PCOS in girls who have not yet reached puberty.

Overview

Polycystic ovary syndrome (PCOS) is a health problem that can affect a woman's menstrual cycle, ability to have children, hormones, heart, blood vessels, and appearance. With PCOS, women typically have:

  • High levels of androgens. These are sometimes called male hormones, although females also make them.
  • Missed or irregular periods
  • Many small cysts in their ovaries. Cysts are fluid-filled sacs.

PCOS is the most common cause of female infertility.

What are the symptoms of Polycystic ovary syndrome?

Not all women with PCOS share the same symptoms. These are some of the symptoms of PCOS:

What causes Polycystic ovary syndrome?

The cause of PCOS is unknown. Most researchers think that more than one factor could play a role in developing PCOS. Genes are thought to be one factor. Women with PCOS tend to have a mother or sister with PCOS. Researchers also think insulin could be linked to PCOS. Insulin is a hormone that controls the change of sugar, starches, and other food into energy for the body to use or store. For many women with PCOS, their bodies have problems using insulin so that too much insulin is in the body. Excess insulin appears to increase production of androgen. This hormone is made in fat cells, the ovaries, and the adrenal gland. Levels of androgen that are higher than normal can lead to acne, excessive hair growth, weight gain, and problems with ovulation.

What causes the symptoms of PCOS?The ovaries are two small organs, one on each side of a woman's uterus. A woman's ovaries have follicles, which are tiny sacs filled with liquid that hold the eggs. These sacs also are called cysts. Each month about 20 eggs start to mature, but usually only one matures fully. As this one egg grows, the follicle accumulates fluid in it. When that egg matures, the follicle breaks open to release it. The egg then travels through the fallopian tube for fertilization. When the single egg leaves the follicle, ovulation takes place.

In women with PCOS, the ovary doesn't make all of the hormones it needs for any of the eggs to fully mature. Follicles may start to grow and build up fluid. But no one follicle becomes large enough. Instead, some follicles may remain as cysts. Since no follicle becomes large enough and no egg matures or is released, ovulation does not occur and the hormone progesterone is not made. Without progesterone, a woman's menstrual cycle is irregular or absent. Plus, the cysts make male hormones, which also prevent ovulation.

Who is at highest risk?

About one in ten women of childbearing age has PCOS, and it can occur in girls as young as 11 years old. In addition, most researchers think that PCOS runs in families. Women with PCOS tend to have a mother or sister with PCOS.

When to seek urgent medical care?

Talk with your doctor if you have irregular, scant or no menstrual periods, are overweight, and have acne or excess facial hair growth.

It appears to be higher rates of miscarriage, gestational diabetes, pregnancy-induced high blood pressure (pre-eclampsia), and premature delivery in women with PCOS. Researchers are studying how the diabetes medicine metformin can prevent or reduce the chances of having these problems while pregnant.

Women with PCOS have greater chances of developing several serious, life-threatening diseases, including type 2 diabetes, cardiovascular disease (CVD), and cancer. Recent studies found that:

  • More than 50 percent of women with PCOS will have diabetes or pre-diabetes (impaired glucose tolerance) before the age of 40.
  • Women with PCOS have a four to seven times higher risk of heart attack than women of the same age without PCOS.
  • Women with PCOS are at greater risk of having hypertension.
  • Women with PCOS have high levels of LDL (bad) cholesterol and low levels of HDL (good) cholesterol.

The chance of getting endometrial cancer is another concern for women with PCOS. Irregular menstrual periods and the absence of ovulation cause women to produce the hormone estrogen, but not the hormone progesterone. Progesterone causes the endometrium to shed its lining each month as a menstrual period. Without progesterone, the endometrium becomes thick, which can cause heavy bleeding or irregular bleeding. Over time, this can lead to endometrial hyperplasia, when the lining grows too much, and cancer.

Diagnosis

There is no single test to diagnose PCOS. Your doctor will take a medical history, perform a physical exam, and possibly take some tests to rule out other causes of your symptoms. During the physical exam, the doctor will want to measure your blood pressure, body mass index (BMI), and waist size. He or she also will check out the areas of increased hair growth, so try to allow the natural hair growth for a few days before the visit. Your doctor might want to do a pelvic exam to see if your ovaries are enlarged or swollen by the increased number of small cysts. A vaginal ultrasound also might be used to examine the ovaries for cysts and check out the endometrium, the lining of the uterus. The uterine lining may become thicker if your periods are not regular. You also might have blood taken to check your hormone levels and to measure glucose (sugar) levels.

Treatment options

Because there is no cure for PCOS, it needs to be managed to prevent problems. Treatment goals are based on your symptoms, whether or not you want to become pregnant, and lowering your chances of getting heart disease and diabetes. Many women will need a combination of treatments to meet these goals. Some treatments for PCOS include:

However, the menstrual cycle will become abnormal again if the pill is stopped. Women may also think about taking a pill that only has progesterone to control the menstrual cycle and reduce the risk of endometrial cancer.

Talk to your doctor about treating all your symptoms, rather than focusing on just one aspect of your PCOS, such as problems getting pregnant. Also, talk to our doctor about getting tested for diabetes regularly. Eating right, exercising, and not smoking also will help to reduce your chances of having other health problems.

Possible complications

  • Increased risk of endometrial cancer
  • Infertility (early treatment of polycystic ovary disease can help prevent infertility or increase the chance of having a healthy pregnancy)
  • Obesity-related (BMI over 30 and waist circumference greater than 35) conditions, such as high blood pressure, heart problems, and diabetes
  • Possible increased risk of breast cancer

Prevention

The National Institue of Child Health and Human Development’s Division of Epidemiology, Statistics, and Prevention Research (DESPR) is exploring early signs of PCOS in teenage girls. Some research suggests that certain signs of PCOS are present at or before puberty. The DESPR research study is examining the relationships among ovarian shape and size, obesity around the waist, and biomarkers of insulin resistance as signs of PCOS in girls who have not yet reached puberty.

Hopefully, ways to prevent PCOS will arise as research on the syndrome continues.
