PCOS Isn't Just About Periods: A Functional Medicine Lens

PCOS often gets introduced through one symptom — an irregular cycle. But it usually shows up as a cluster: stubborn weight, fatigue, skin and hair changes, mood swings, cravings. Looking at the whole picture, rather than one symptom at a time, is where a functional approach earns its keep.

The thread running through it: insulin

For most women with PCOS, insulin resistance sits underneath the symptoms. When cells respond less well to insulin, the body makes more of it — and that ripples into cycles, energy, skin and weight. Insulin sensitivity responds well to daily lifestyle levers, which is why it's the highest-leverage place to start.

Markers worth tracking

Beyond a scan, the metabolic and hormonal picture matters: fasting insulin, the triglyceride-to-HDL ratio, HbA1c, and androgens like free testosterone and DHEA-S. These show whether insulin resistance and inflammation are driving the pattern — and they're the numbers that shift as your habits change.

Levers that work

• Plate shape: protein and fibre first, refined carbs and sugar dialled down — this blunts the spikes that drive insulin.

• Movement after meals: even a short walk helps muscles soak up blood sugar.

• Strength work: more muscle means better insulin sensitivity over time.

• Sleep and stress: both directly affect blood sugar and cravings — they're core, not soft.

'Eat better and exercise' is true but useless on its own. The work is turning it into specific, doable habits that fit an Indian kitchen and a real schedule — and staying consistent long enough to see your cycles, energy and labs shift.
