Is PCOS Dangerous? Polycystic Ovary Syndrome (PCOS): Symptoms, Risks and Treatment

What is Polycystic Ovary Syndrome (PCOS)?

Polycystic ovary syndrome (PCOS), also known as polycystic ovarian syndrome, is a common hormonal disorder caused by an imbalance of reproductive hormones in females of reproductive age. This hormonal imbalance can affect the ovaries and may lead to changes in your menstrual cycle, fertility and overall health and appearance. PCOS affects about 5% to 26% of women worldwide.

If you have been experiencing irregular or missed periods, unexpected weight changes, acne or difficulty getting pregnant, PCOS could be one of the possible reasons. These symptoms can feel confusing or easy to ignore at first, but they often point to an underlying hormonal imbalance that needs attention.

PCOS is a common but manageable cause of infertility. Normally, the ovaries release an egg each month as part of a healthy menstrual cycle. However, in women with PCOS, the egg may not develop properly or may not be released during ovulation. This can lead to symptoms such as irregular or missed menstrual periods.

Why is it named Polycystic Ovarian Syndrome (PCOS)?

It is named so because of the appearance of the ovaries, which contain multiple immature follicles, also called cysts or small, fluid-filled sacs. These undeveloped follicles develop due to hormonal imbalances that prevent eggs from maturing and being released, leading to an accumulation of follicles that may appear as cysts on an ultrasound.

However, the name is misleading, as the “cysts” in the ovaries are not typically true fluid-filled ovarian cysts; instead, they are immature follicles.

Is PCOS Dangerous?

PCOS is not inherently life-threatening. However, if left untreated, polycystic ovary syndrome can lead to long-term health risks such as heart disease, type 2 diabetes, endometrial cancer and other metabolic complications.

Being informed about the symptoms, risks and treatment options for PCOS can help you make the right lifestyle changes and healthcare decisions to manage the condition effectively and support long-term health.

What are the Symptoms of PCOS?

You may start noticing symptoms of PCOS soon after your first period, or you may only discover the condition later when you experience weight gain or difficulty getting pregnant. Symptoms of polycystic ovary syndrome can vary widely, but some of the most common signs include:

• Irregular or Missed Periods

  One of the most significant symptoms of PCOS is irregular menstrual periods. If you have the condition, you may have oligomenorrhea (fewer periods) or amenorrhea (absence of periods). Some females get fewer than eight menstrual periods, and some do not get periods at all. The lack of ovulation can make it difficult to conceive and also lead to a hormonal imbalance.

• Weight Gain and Difficulty Losing Weight

  Unexplained weight gain, especially around the abdomen, and difficulty losing weight are common symptoms of polycystic ovary syndrome. About 4 in 5 women with PCOS are affected by obesity. However, this rate can vary depending on region and population.

• Heavy Periods

  Heavy periods can be a challenging symptom of PCOS. In some cases, fewer periods may become heavier or longer than usual because the uterine lining builds up over time.

• Acne or Oily Skin

  Increased androgen levels (male sex hormones) can lead to oily skin and acne breakouts, especially on the face, upper back and chest, in women with PCOS. This type of acne is often resistant to over-the-counter (OTC) treatments and may require hormone-based treatment.

• Excess Hair Growth (Hirsutism)

  Increased androgen levels can also lead to excess hair growth (hirsutism) on the face, abdomen, back and chest.

• Thinning of Hair or Male Pattern Baldness

  You may also experience hair thinning or male-pattern baldness in PCOS. This happens because higher levels of androgens can cause hair follicles to shrink, leading to hair thinning.

• Darkening of Skin

  Dark, velvety patches of skin may appear on the breasts, neck and groin. This condition, called acanthosis nigricans, is often associated with insulin resistance.

• Mood Swings and Mental Health Problems

  The hormonal imbalance and physical symptoms of PCOS can lead to mood swings and mental health issues such as depression, stress and anxiety.

What are the Risks for PCOS?

You may be at greater risk of developing polycystic ovary syndrome if you have:

• First Degree Relatives

  A 2019 study suggests that polycystic ovary syndrome runs in families. If your mother or sister has PCOS, you are more likely to develop the condition. However, having close relatives with PCOS does not always mean you will also have it.

• Insulin Resistance

  According to 2023 research, 65% to 95% of women with PCOS also have insulin resistance and hyperinsulinemia. When body cells do not respond properly to insulin, insulin demand increases. The pancreas produces more insulin to compensate, resulting in hyperinsulinemia. This excess insulin can trigger the ovaries to produce more androgens.

• Inflammation

  Inflammation is another risk factor for PCOS. If you have polycystic ovary syndrome, increased levels of inflammation may be present in your body. Obesity and insulin resistance are common contributing factors. Studies have linked excess inflammation to higher levels of male sex hormones (androgens).

• Premature Adrenarche

  Premature adrenarche (PA) refers to the early development of pubic hair or body odour before age 8. It is considered a PCOS risk factor because it may act as a precursor to persistent hyperandrogenism, ovarian dysfunction and insulin resistance.

How is PCOS Dangerous?

PCOS is not immediately life-threatening, but it can become dangerous when left untreated over time. If not managed, it may increase the risk of several long-term health complications.

• Infertility: To conceive, ovulation is required. However, in PCOS, ovulation may become irregular or absent. This can reduce fertility, and PCOS is one of the leading causes of infertility in women.
• Metabolic Syndrome: Metabolic syndrome includes high blood pressure, high blood sugar, low “good” cholesterol and high “bad” cholesterol. Together, these increase the risk of heart disease, stroke and type 2 diabetes. This is one way PCOS can become dangerous if unmanaged.
• Depression: Hormonal imbalance and ongoing symptoms can affect mental health. Women with PCOS may have a higher risk of depression, anxiety and mood-related disorders.
• Endometrial Hyperplasia and Cancer: PCOS can increase the risk of endometrial hyperplasia due to irregular or absent menstrual cycles. This leads to thickening of the uterine lining (endometrium), which over time may increase the risk of endometrial cancer if left untreated.
• Cardiac Issues: One of the more serious long-term risks of unmanaged PCOS is cardiovascular disease. This includes an increased risk of heart attack and stroke, especially in women who also have obesity, diabetes or hypertension.

What is the Treatment of PCOS?

Treatments for PCOS can include non-pharmacological as well as pharmacological approaches. These methods aim to manage PCOS symptoms, improve hormonal balance and reduce long-term health risks.

1. Non-Pharmacological Therapies

Lifestyle Tips to Manage PCOS Symptoms: Treatments for PCOS can include non-pharmacological therapy, such as lifestyle modifications to manage the symptoms.

• Start with weight management. Maintaining a moderate weight can help regulate menstrual cycles and improve PCOS symptoms.
• Diet is also important. A low-carbohydrate diet may help with insulin resistance, weight loss, total cholesterol and LDL levels.
• Exercise is key. The International PCOS guidelines recommend at least 150 minutes of moderate physical activity, 70 minutes of intense activity or a combination of both.

Psychological Counselling and Support: PCOS can cause physical as well as emotional challenges, especially related to infertility, body image concerns and other complications.

• Supportive psychological counselling, such as CBT (Cognitive Behavioural Therapy) and DBT (Dialectical Behavioural Therapy), can help address emotional concerns and promote coping and resilience.
• Integrative care may also include couples counselling, which can support sexual health and fertility-related concerns.

2. Pharmacological Therapies

Medications

• Birth control pills and other hormonal medications can help regulate menstrual cycles and relieve symptoms of PCOS, such as acne and excess hair growth.
• Taking birth control pills or progestins can help restore hormonal balance, regulate cycles and reduce the risk of endometrial cancer.
• Metformin is a medication used to treat type 2 diabetes by improving insulin sensitivity. It can also help improve insulin levels in women with PCOS and may support ovulation and menstrual regularity.
• Clomiphene may be prescribed if you have PCOS and are trying to conceive. However, it can increase the chance of multiple births, so medical supervision is important.
• Hair removal medications such as eflornithine cream can help slow unwanted hair growth caused by PCOS.

Surgery

Surgery may be considered as a last option to improve fertility if other treatments do not work.

Laparoscopic ovarian drilling is a procedure that can reduce androgen levels and improve ovulation in women with PCOS. It uses laser or heat to create small holes in the ovaries to help restore ovulation.

Conclusion

PCOS (Polycystic ovary syndrome) is a hormonal condition that affects the ovaries due to an imbalance in reproductive hormones. This can disrupt ovulation, meaning eggs may not be released regularly or at all, leading to irregular menstrual cycles and fertility challenges.

When asking, “Is PCOS dangerous if left untreated?” The answer is that while it is not immediately life-threatening, unmanaged PCOS can increase the risk of long-term complications such as diabetes, cardiovascular disease and endometrial cancer. This underscores the importance of early diagnosis and consistent management.

PCOS is not a condition you “live with” without support. With the right combination of lifestyle changes, medical treatment and ongoing care, most symptoms can be effectively managed, and many women can improve their fertility and long-term health outcomes.
