PCOS

What is actually driving it

PCOS is diagnosed on a combination of irregular or absent ovulation, raised androgens, and the appearance of the ovaries on ultrasound. What that description leaves out is the mechanism most amenable to treatment: insulin resistance is present in a large majority, including in many women of normal weight.

The chain is reasonably direct. Higher insulin drives the ovaries to produce more androgens and lowers the protein that binds them in circulation, so more free androgen is available. That produces the irregular cycles, the acne and the hair changes. Improving insulin sensitivity works backwards along that chain, which is why it affects symptoms that look unrelated to blood sugar.

What helps

• Modest weight loss where there is excess — around 5–10% can restore ovulation in a meaningful proportion of women. Modest is the operative word; this is not a transformation project.
• Lower glycaemic load, and carbohydrate distribution — no single "PCOS diet" has proven superior, but approaches that blunt the insulin response have the most consistent support.
• Resistance training — muscle improves insulin sensitivity directly, and it works for lean PCOS where weight loss is neither available nor appropriate.
• Protein and fibre at each meal, which changes the glycaemic response of the same food.
• Inositol — reasonable evidence for insulin sensitivity and ovulatory function, and one of the few supplements in this area worth discussing seriously.

What does not help: being told to lose weight without support, and restrictive dieting, which has a particularly poor record in a population with an elevated rate of disordered eating.

Lean PCOS is not a different disease

Perhaps a fifth to a third of women with PCOS are not overweight, and they are routinely dismissed — told they cannot have it, or given advice built entirely around weight loss they do not need.

Insulin resistance is frequently present anyway. The levers are the same minus the weight one: carbohydrate distribution, resistance training, protein and fibre, sleep. If you have been told your PCOS is not real because of your weight, that is worth pushing back on.

The long game

PCOS carries elevated long-term risk of type 2 diabetes, gestational diabetes and cardiovascular disease, and that risk is present regardless of whether fertility is the current concern.

Which reframes the work. The same changes that regularise cycles are the ones that address the metabolic risk sitting behind them, so this is worth doing in the years when nothing is urgent rather than only when something is.

What the first appointment covers

• Cycle history, and what has already been tried
• Markers: HbA1c or fasting insulin, lipids, and androgens if available
• Whether fertility is a current goal, which changes the timeline but not the direction
• Carbohydrate distribution across the day, before any restriction
• Resistance training, particularly where weight loss is not the target
• Any history of disordered eating, asked directly, because it changes how this should be approached

When to see a doctor

Diagnosis, medication such as metformin or hormonal treatment, and fertility care belong with your physician, gynaecologist or endocrinologist. Nutrition works alongside those rather than instead of them.

Absent periods, rapid onset of significant hair growth or voice change, or sudden severe pelvic pain need medical assessment rather than dietary advice.

Booking, and what it costs

Two routes, and which one is cheaper depends entirely on your plan rather than on which sounds better.

Through insurance. Medical nutrition therapy is a covered benefit on many plans, sometimes with no copay at all. Booking runs through Fay Nutrition, which checks your benefits before the first appointment so you know the number in advance rather than six weeks later.

Self-pay. A flat $140 per session through CognitiveMind — no benefits check, no prior authorization, no denial arriving after the fact. If your coverage is thin, absent, or has a deductible you will not meet this year, this is often the more predictable of the two.
