PCOS: what it is, and what it is not

A great many women arrive at a first appointment already believing they have PCOS, usually on the strength of one ultrasound report from some years earlier. Often they have carried a lot of worry about their fertility since that day, and often nobody has sat down and explained what the diagnosis does and does not mean.

A scan alone is not the diagnosis

Polycystic-looking ovaries — many small follicles visible on a scan — are common, particularly in younger women, and on their own they do not make the diagnosis. They are one of three findings, and the diagnosis usually needs two of the three.

The other two are irregular or absent ovulation, and signs of raised male-type hormones, either on a blood test or clinically. Thyroid problems and one or two other conditions can produce a similar picture, which is why blood tests matter and why a report saying 'polycystic ovaries' is a starting point rather than a conclusion.

What it actually means for you

PCOS can make periods irregular and can make conceiving take longer. It does not mean you cannot have children — most women with PCOS can — and it is not a condition that gets steadily worse over time.

It is associated with a higher long-term risk of diabetes, which is the part that gets least attention and probably matters most. That is worth knowing early, because it is the part you can do something about.

Be specific about what is troubling you

PCOS presents as several quite different problems and they have different answers. Irregular periods, unwanted hair growth, weight that will not shift, and difficulty conceiving are not one problem with one treatment.

When you come in, it is worth deciding which of these actually brought you. Treatment for someone who wants to conceive this year is different from treatment for someone who wants her cycle to settle and is not thinking about children yet.

On cures

PCOS is managed rather than cured, and for many women it becomes much less troublesome over time and with treatment. Anyone offering you a cure — a diet, a supplement, a course of treatment that permanently resolves it — is not being straight with you.

What can be done is real and worth doing. It is just not a cure, and the difference matters.
