Polycystic Ovary Syndrome (PCOS): Types of PCOS, causes, symptoms, and best treatment options

Key Points

• 5-10% of women in their reproductive years have PCOS, a hormonal disorder characterised by high testosterone, irregular ovulation, and the potential for metabolic problems if left untreated.
• There are four types that require particular tests: post-pill (post-contraceptive onset), inflammatory (chronic inflammation driven), adrenal (stress induced), and insulin-resistant (most prevalent, metabolic-linked).
• Genetics (20-40% risk if familial), insulin resistance, inflammation, and environmental factors such as endocrine disruptors are all contributing factors.
• Treatment focusses on lifestyle (diet/exercise), medications (metformin, contraceptives), and therapies like inositol. Remission rates can reach 50% with continued care. Symptoms include irregular menstruation, excess hair/acne, weight gain, infertility, and mood swings.

Introduction

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women of childbearing age. Recent estimates from health organisations say that it affects about 5–10% of women around the world. This condition is caused by an imbalance in reproductive hormones, which can cause a number of physical and metabolic problems. It is important to know what PCOS is in order to find it early and treat it.
This article talks about the different types of PCOS, what causes it, what the symptoms are, and what the best ways to treat it are. It also talks about the signs and symptoms of PCOS, the causes of PCOS, the different ways to get rid of PCOS, and things to think about when trying to permanently cure PCOS.

What is PCOS?

PCOS, or polycystic ovary syndrome, is characterized by the ovaries producing excessive amounts of androgens, the hormones typically associated with males. This hormonal imbalance can result in the formation of small, fluid-filled sacs (cysts) on the ovaries, though not all women with PCOS develop these cysts. The syndrome disrupts normal ovulation and menstrual cycles, often leading to fertility challenges.

Diagnosis typically requires at least two of the following criteria: irregular ovulation, elevated androgen levels (evident through blood tests or physical signs), and polycystic ovarian morphology on ultrasound. PCOS is not curable but can be effectively managed to reduce symptoms and prevent complications such as type 2 diabetes, cardiovascular disease, and endometrial cancer. Early intervention is key, as it can mitigate long-term health risks.

What are the types of PCOS

Types of PCOS are classified based on underlying mechanisms, which influences tailored treatment plans. While traditional diagnostics focus on general symptoms, recent classifications identify four primary phenotypes. These distinctions help clinicians address root causes more precisely.

1. Insulin-Resistant PCOS: This is the most prevalent form, accounting for 65-70% of cases. It stems from the body’s reduced sensitivity to insulin, a hormone that regulates blood sugar. High insulin levels stimulate the ovaries to produce more androgens, exacerbating symptoms. Women with this type often experience central weight gain and metabolic disturbances.
2. Inflammatory PCOS: Chronic inflammation plays a central role here, driven by factors like poor diet, environmental toxins, or gut dysbiosis. Elevated inflammatory markers, such as C-reactive protein, are detectable in blood tests. This type amplifies androgen production and is linked to fatigue, joint pain, and skin issues beyond standard symptoms.
3. Adrenal PCOS: Also known as stress-related or hidden-cause PCOS, this variant involves overproduction of androgens by the adrenal glands, particularly DHEA-S. It is commonly triggered by prolonged stress, which activates the hypothalamic-pituitary-adrenal axis. Unlike other types, insulin resistance is minimal, but cortisol imbalances predominate.
4. Post-Pill PCOS: Symptoms emerge or intensify after discontinuing oral contraceptives. The pill can suppress natural hormone production, and withdrawal unmasks underlying imbalances. This type often resolves with time but requires monitoring to prevent persistence.

Identifying the specific type of PCOS involves comprehensive testing, including hormone panels and inflammation markers. This classification, supported by endocrinologists, allows for targeted interventions.

PCOS causes: Underlying factors

The specific cause of PCOS is unknown. Factors that may play a role are:

Insulin resistant: Insulin is a hormone that the pancreas produces. It enables cells to utilise sugar, the body’s major energy source. If cells develop resistant to insulin, blood sugar levels can rise. This can cause your body to produce more insulin in order to lower blood sugar levels.

Too much insulin may cause your body to produce too much of the male hormone androgen. You could have problems with ovulation, which is the process by which eggs are released from the ovary. One sign of insulin resistance is dark, velvety patches of skin on the lower part of the neck, armpits, groin or under the breasts. A bigger appetite and weight gain may be other signs.

Low-grade irritation:  When an infection or injury occurs, white blood cells produce chemicals. We refer to this reaction as low-grade inflammation. According to research, PCOS patients have a kind of chronic, low-grade inflammation that causes polycystic ovaries to manufacture androgens. Heart and blood vascular issues may result from this.
Genetics:  Certain genes may be connected to PCOS, according to research. The development of PCOS may be influenced by a family history of the disorder.

Excess androgens: PCOS can cause the ovaries to produce excessive amounts of androgen. Excess androgen interferes with ovulation. This means that eggs are not produced on a regular basis and are not released from the follicles in which they develop. Excess androgen can cause hirsutism and acne.

PCOS symptoms: Recognizing the signs

PCOS symptoms usually appear around the first menstrual period. Sometimes symptoms appear after you’ve had periods for a while.

The symptoms of PCOS vary. PCOS is diagnosed when you have at least two of the following:

Irregular periods: Common indications of PCOS include having few menstrual periods or irregular periods. Periods that linger for several days or longer than usual are also considered abnormal. For example, you may have fewer than nine periods every year. These intervals may occur more than 35 days apart. You may have difficulty getting pregnant.

Too much androgen: Excess facial and body hair may be caused by elevated amounts of the hormone androgen. This is called hirsutism. Severe acne and male-pattern baldness can also occur.

Polycystic ovaries: Your ovaries might be larger. Many follicles carrying immature eggs may form along the ovary’s border. The ovaries might not function properly.

Polycystic ovary syndrome symptoms can onset during adolescence but may worsen with age. Not all women experience cysts; the term “polycystic” refers more to the hormonal profile than ovarian appearance.

PCOS Treatment:

Effective PCOS symptoms and treatment strategies focus on symptom relief and risk reduction. Treatment is individualized, prioritizing goals such as fertility, weight management, or cosmetic concerns.

Lifestyle Modifications

Foundational to all PCOS treatment, these changes yield significant improvements. A balanced diet emphasizing low-glycemic index foods, such as vegetables, whole grains, and lean proteins, helps stabilize insulin levels. Studies show that losing 5-10% of body weight can restore ovulation in 50-60% of women.

Regular exercise, combining aerobic activity (150 minutes weekly) and resistance training, enhances insulin sensitivity and reduces androgens. Stress management techniques, including mindfulness or yoga, are particularly beneficial for adrenal PCOS.

Pharmacological options

Medications address specific PCOS symptoms:

• Hormonal contraceptives: Combined oral pills regulate cycles, lower androgens, and improve acne/hirsutism in 70% of users.
• Insulin sensitizers: Metformin reduces insulin resistance, aids weight loss, and boosts fertility rates by 30-50%.
• Anti-androgens: Spironolactone or finasteride targets hair growth and acne, often combined with contraception to prevent pregnancy risks.
• Ovulation inducers: Clomiphene or letrozole for fertility, with success rates of 60-80% in responsive patients.

For inflammatory PCOS, anti-inflammatory agents like omega-3 supplements or NSAIDs may be adjunctive. Surgical options, such as ovarian drilling, are reserved for refractory infertility.

How to Get Rid of PCOS: Long-Term Management

How to get rid of PCOS involves sustained efforts rather than quick fixes, as the condition is chronic. While how to cure PCOS permanently is not currently possible, PCOS persists lifelong for most women, symptom remission is achievable. Up to 50% of women achieve regular cycles through persistent lifestyle adherence.

Monitoring includes annual screenings for glucose intolerance and lipids. Emerging therapies, such as inositol supplements, show promise in improving insulin signaling and ovulation. Multidisciplinary care, involving endocrinologists, dietitians, and gynecologists, optimizes outcomes. Research as of 2025 highlights gut microbiome modulation via probiotics as a potential avenue for reducing inflammation.
