PolyCystic Ovarian Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women during their reproductive years. It is characterized by irregular menstrual periods or infrequent periods that may last longer than usual. One of the key factors in PCOS is an elevated level of androgen, a male hormone, in the body.

With PCOS, small fluid-filled sacs called cysts develop along the outer edge of the ovaries. These cysts contain immature eggs, known as follicles, which fail to be released regularly. The exact cause of PCOS is still unknown, but early diagnosis and treatment, along with weight loss, can help lower the risk of long-term complications such as type 2 diabetes and heart disease.

The symptoms of PCOS can vary. They often begin around the time of the first menstrual period, but they may develop later. It is regarded as a syndrome because of the symptomatic presentations (a syndrome is a group of symptoms which consistently occur together or a condition characterized by a set of associated symptoms). To receive a PCOS diagnosis, you should have at least two of the following symptoms:

1. Irregular periods: Having fewer menstrual periods or experiencing irregular periods is a common sign of PCOS. Periods may last for many days or occur less frequently, such as fewer than nine periods a year with intervals of more than 35 days. Difficulty getting pregnant can also be associated with irregular periods.
2. Excess androgen: Elevated levels of androgen hormone can lead to excessive facial and body hair growth, a condition called hirsutism. Severe acne and male-pattern baldness can also occur in some cases.
3. Polycystic ovaries: Women with PCOS may have enlarged ovaries with multiple follicles containing immature eggs. The ovaries may not function properly in releasing eggs as they should.

It’s important to note that symptoms of PCOS can be more severe in individuals with obesity. If you are concerned about your periods, experiencing difficulties in getting pregnant or displaying signs of excess androgen, it is advisable to consult with a healthcare provider.

The exact cause of PCOS is not yet fully understood. However, several factors may contribute to its development, including:

1. Insulin resistance: Insulin is a hormone produced by the pancreas that helps cells utilize sugar for energy. In insulin resistance, cells become less responsive to insulin, resulting in higher levels of insulin in the body. This can lead to increased production of androgen hormones, disrupt ovulation, and contribute to PCOS symptoms. Signs of insulin resistance may include dark patches of skin, increased appetite, and weight gain.
2. Low-grade inflammation: Individuals with PCOS often experience a chronic, low-grade inflammation that triggers the production of androgens by the polycystic ovaries. This inflammation can contribute to heart and blood vessel problems.
3. Heredity: There is evidence to suggest that certain genes may be linked to PCOS. Having a family history of the condition may increase the likelihood of developing PCOS.
4. Excess androgen: PCOS is associated with high levels of androgen hormones produced by the ovaries. Elevated androgen levels can disrupt ovulation, preventing eggs from developing and being released regularly. Additionally, excess androgens can cause hirsutism and acne.

Complications

Several health disorders may arise from PCOS because it affects hormones and causes instability in the body. Complications include:

1. Infertility: PCOS is a leading cause of female infertility. Hormonal imbalances and irregular ovulation can make it difficult for women with PCOS to conceive.
2. Gestational diabetes or pregnancy-induced high blood pressure: Women with PCOS have an increased risk of developing gestational diabetes (high blood sugar during pregnancy) and pregnancy-induced high blood pressure (preeclampsia).
3. Miscarriage or premature birth: Women with PCOS have a higher risk of experiencing miscarriages or giving birth prematurely compared to women without PCOS.
4. Nonalcoholic steatohepatitis (NASH): NASH is a severe inflammation of the liver caused by the buildup of fat in the liver. Women with PCOS, particularly those who are overweight or obese, have an increased risk of developing NASH.
5. Metabolic syndrome: Metabolic syndrome is a cluster of conditions, including high blood pressure, high blood sugar, unhealthy cholesterol levels, and excess abdominal fat. Women with PCOS are more likely to develop metabolic syndrome, which significantly increases the risk of cardiovascular diseases such as heart disease and stroke.
6. Type 2 diabetes or prediabetes: PCOS is associated with insulin resistance, a condition in which the body’s cells become less responsive to insulin. This can lead to elevated blood sugar levels and an increased risk of developing type 2 diabetes or prediabetes.
7. Sleep apnea: Sleep apnea is a sleep disorder characterized by interrupted breathing during sleep. Women with PCOS have a higher prevalence of sleep apnea, likely due to factors such as obesity and hormonal imbalances.
8. Depression, anxiety, and eating disorders: PCOS can have a significant impact on a woman’s emotional well-being. Hormonal imbalances, fertility challenges, and body image concerns can contribute to depression, anxiety, and eating disorders.
9. Cancer of the uterine lining (endometrial cancer): Women with PCOS have an increased risk of developing endometrial cancer, which is cancer of the lining of the uterus. This risk is primarily associated with the hormonal imbalances and irregular menstrual cycles seen in PCOS.

Management options

While polycystic ovary syndrome (PCOS) cannot be cured, the symptoms can be managed through various treatment options. Here are some of the main treatment options for PCOS:

1. Lifestyle changes: In overweight women, losing excess weight can significantly improve the symptoms and reduce the risk of long-term health problems associated with PCOS. Even a modest weight loss of 5% can have a positive impact. Lifestyle changes may include regular exercise and a healthy, balanced diet.
2. Medications: Different medications can be used to address specific symptoms of PCOS. Some examples include:

• Irregular or absent periods: The contraceptive pill or intermittent courses of progestogen tablets can be used to induce regular periods and reduce the risk of endometrial cancer.
• Fertility problems: Clomifene is a medication that may be recommended to stimulate ovulation in women trying to get pregnant. If clomifene is not effective, metformin may be prescribed to lower insulin and blood sugar levels, stimulate ovulation, and reduce the risk of miscarriage.
• Unwanted hair growth and hair loss: The combined oral contraceptive pill can help manage excessive hair growth (hirsutism) and hair loss (alopecia). Eflornithine cream can be used to slow down the growth of unwanted facial hair. Laser hair removal and other hair removal methods may also be options.
• Other medications: Anti-androgens like cyproterone acetate, spironolactone, flutamide, and finasteride may be prescribed for excessive hair growth. Minoxidil cream can be recommended for hair loss on the scalp.

Conclusion

It’s important to note that the specific treatment plan for PCOS should be tailored to each individual’s symptoms and needs. Consulting with a healthcare professional, such as a gynecologist or endocrinologist, is crucial to determine the most appropriate treatment approach. They can evaluate your specific situation, discuss potential risks and benefits, and provide personalized recommendations for managing PCOS.
