Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder that affects people with ovaries, often during their reproductive years. It is estimated to affect 1 in 10 women, though the prevalence can vary. The condition is named for the numerous small cysts that often form on the ovaries, though not everyone with PCOS will have cysts.

Key Features of PCOS:
Hormonal Imbalance:

People with PCOS often have an imbalance of reproductive hormones, including elevated levels of androgens (often referred to as "male hormones," like testosterone).
This can disrupt the normal menstrual cycle, leading to irregular periods, anovulation (lack of ovulation), and infertility.
Irregular Menstrual Cycles:

Many individuals with PCOS experience infrequent or absent periods, which can make it difficult to predict ovulation or conceive.
Ovarian Cysts:

In PCOS, the ovaries may become enlarged and contain multiple small cysts (fluid-filled sacs). These cysts are actually immature follicles that failed to release eggs, a result of hormonal imbalances.
Excess Androgens:

Elevated androgen levels can cause physical symptoms like excess facial or body hair (hirsutism), acne, and scalp thinning (alopecia).
Insulin Resistance:

Many people with PCOS also have insulin resistance, which means their cells don’t respond well to insulin. This can lead to higher levels of insulin in the blood, which in turn can exacerbate hormonal imbalances and increase the risk of type 2 diabetes.
Symptoms:
Irregular or absent periods
Excess facial or body hair (hirsutism)
Acne or oily skin
Thinning hair (scalp hair loss)
Weight gain or difficulty losing weight
Dark patches of skin (acanthosis nigricans), often in body folds like the neck or armpits
Infertility or difficulty getting pregnant
Fatigue and mood disturbances
Causes:
The exact cause of PCOS is unknown, but several factors may contribute:

Genetics: A family history of PCOS increases the likelihood of developing the condition.
Hormonal Imbalance: Elevated androgens and insulin resistance are key factors in the development of PCOS.
Environmental Factors: Diet, stress, and other lifestyle factors may influence the severity of symptoms.
Diagnosis:
To diagnose PCOS, healthcare providers typically look for:

Irregular menstrual cycles (or lack of ovulation).
Signs of excess androgens (e.g., hirsutism, acne, male-pattern hair loss).
Ultrasound: Many people with PCOS will have a characteristic appearance on an ultrasound, including enlarged ovaries with multiple small cysts.
The diagnosis often follows the Rotterdam Criteria (2003), which requires at least two of the following:

Irregular or absent ovulation (menstrual cycles).
Elevated androgen levels or symptoms.
Ovarian cysts on ultrasound.
Management & Treatment:
There’s no cure for PCOS, but treatments can help manage symptoms:

Hormonal Birth Control:

Birth control pills, patches, or rings can regulate menstrual cycles, reduce excess hair growth, and improve acne.
Metformin:

This medication is often prescribed to help manage insulin resistance and improve ovarian function. It may also assist with weight management.
Anti-androgen Medications:

Drugs like spironolactone can block the effects of androgens, reducing symptoms like hirsutism and acne.
Ovulation-Inducing Drugs:

For those trying to conceive, medications like clomiphene citrate or letrozole can help stimulate ovulation.
Lifestyle Changes:

Maintaining a healthy weight and engaging in regular physical activity can help improve insulin sensitivity, regulate periods, and improve fertility.
Fertility Treatments:

If medication doesn’t work, assisted reproductive technologies like in vitro fertilization (IVF) may be considered for people with fertility struggles.
Other Symptom Management:

For cosmetic issues like excessive hair growth, laser hair removal or electrolysis may be recommended.
Topical or oral medications can also help manage acne.
Long-Term Health Risks:
PCOS is associated with a number of long-term health risks, especially if left untreated:

Type 2 diabetes: Due to insulin resistance.
Heart disease: Increased risk due to higher levels of insulin and other metabolic disturbances.
Endometrial cancer: Irregular periods can lead to a buildup of the uterine lining, increasing the risk of cancer over time.
Sleep apnea: People with PCOS are at higher risk for sleep apnea, especially if they are overweight.
Conclusion:
While PCOS can be challenging to manage, many people with the condition can live healthy lives with appropriate treatment and lifestyle changes. If you suspect you have PCOS or are struggling with symptoms, it’s important to see a healthcare provider to discuss diagnosis and treatment options. Early intervention can help manage symptoms and reduce the risk of long-term complications.
