PCOS: Recognizing the Signs and Living Well With It

Polycystic ovary syndrome, usually shortened to PCOS, affects roughly one in ten women of reproductive age. It is the single most common hormonal disorder in this group, and across Africa it remains widely under-diagnosed. Many women live with PCOS for years before getting a clear answer.

The name is misleading. What look like cysts in PCOS are actually small, immature follicles on the ovaries that show up on ultrasound. They are not dangerous on their own, and you can have PCOS without visible cysts on imaging. The diagnosis rests on a broader picture, not on the ovary alone.

Three core features define PCOS, and you need at least two of them for a diagnosis. The first is irregular or absent periods. The second is signs of high androgens (male-pattern hormones), which can show up as persistent acne, hair growth on the chin or chest, or scalp hair thinning. The third is polycystic-appearing ovaries on ultrasound.

Insulin resistance sits at the centre of most PCOS cases. The body's cells stop responding well to insulin, the pancreas compensates by making more, and high insulin pushes the ovaries to produce more androgens. That cascade explains both the period changes and the metabolic risks.

Beyond fertility, PCOS raises long-term risk for type 2 diabetes, high blood pressure, fatty liver disease, and cardiovascular conditions. These are not certainties, but they are real probabilities that early management can reduce significantly.

Common signs that something might be off include cycles that are consistently irregular or longer than 35 days, weight that is hard to shift even with reasonable habits, persistent acne in adulthood, sudden hair loss or thinning, dark velvety patches on the skin (a condition called acanthosis nigricans, often around the neck), and fatigue that does not match your sleep.

Diagnosis is straightforward when the right tests are run. A doctor will typically order hormonal blood work (testosterone, free androgen index, LH, FSH, prolactin, thyroid function), a fasting insulin and glucose, sometimes a HbA1c, and a pelvic ultrasound. The pattern of results, not any single number, is what confirms PCOS.

Treatment is multi-layered. There is no single cure, but there are well-evidenced strategies that meaningfully change the trajectory. Lifestyle changes form the foundation, followed by targeted medication where useful.

Diet matters more in PCOS than in most conditions. The goal is to keep insulin and blood sugar steady. That means meals built around protein, fibre, and healthy fats, with refined carbohydrates kept to a minimum. White bread, sugary drinks, and ultra-processed snacks tend to worsen symptoms quickly. Local options that work well include beans, lentils, fish, eggs, leafy greens, plantain in moderation, and whole-grain cereals.

Exercise is one of the most powerful single interventions. Even 30 minutes of brisk walking five times a week improves insulin sensitivity within weeks. Strength training adds another layer of benefit, building muscle that acts as a metabolic sink for glucose.

Sleep is often overlooked. Poor sleep worsens insulin resistance directly, and PCOS is associated with higher rates of obstructive sleep apnoea. If you snore, wake up tired despite enough hours, or have noticed others mention pauses in your breathing at night, mention it to your doctor.

Medications fill specific gaps. Metformin improves insulin sensitivity and often regulates cycles. Combined oral contraceptive pills can manage cycles, reduce androgens, and clear acne. Spironolactone is helpful for stubborn unwanted hair and acne. For those trying to conceive, ovulation-induction medications such as letrozole are first-line.

Mental health needs deliberate attention. PCOS roughly doubles the risk of depression and anxiety, partly because of hormonal changes and partly because of the toll of weight changes, fertility concerns, and skin or hair issues. Therapy, peer support, and medication where indicated are not afterthoughts.

Most importantly, PCOS is manageable. With the right combination of changes, women with PCOS run businesses, raise families, and live full lives. The condition rewards consistent care more than dramatic interventions, and small habits compounded across years are often what move the needle most.
