PCOD, PCOS and PMOS are the same thing

In India a report might say PCOD, a website says PCOS, and the newest papers say PMOS. All three are one condition, and nothing about a diagnosis changes between those words.

What the letters actually say

PCOD is polycystic ovarian disease. PCOS is polycystic ovary syndrome. The difference between those two names is one word at the end.

A syndrome is a group of features that turn up together. That is what this is: irregular or absent periods, raised androgens, and the appearance of the ovaries on an ultrasound. A diagnosis needs two of those three, which is why two women with the same diagnosis can look quite different on paper, and why the ovaries can look entirely ordinary.

PCOD is the older term and it stayed in everyday use in India long after the literature moved on. Plenty of clinics, labs and reports still print it.

Three names, one set of criteria

Whichever word is written at the top of a report, the condition is identified the same way. The Rotterdam criteria are what a diagnosis is made against, and they also require other causes to be ruled out first, thyroid disease and raised prolactin among them. That is part of why a thyroid panel turns up so often in this workup.

The largest Indian prevalence study applied those criteria to 8,993 women aged 18 to 40 across eight states, and found 19.6%, close to one in five (Ganie et al., 2024). The range around that figure is wide, 12.7% to 29.2%.

So a different name does not mean a different test, a different threshold, or a milder version of the same thing. The name is the only part that varies.

Why there are now three

In May 2026 the condition was renamed again, to Polyendocrine Metabolic Ovarian Syndrome. That decision came out of a consensus process involving 56 organisations and 14,360 survey responses (Teede et al., 2026).

The reasoning is covered in what the rename changed. The short version is that the old name pointed at ovarian cysts, which are not required for a diagnosis, and at one organ, in a condition that works across the hormonal and metabolic systems.

That means PCOD, PCOS and PMOS will all be in circulation for some time. Records and requisitions take years to catch up, and the two older names are what most of the internet still says.

If your reports say PCOD

You can read anything written about PCOS or PMOS as being about your own condition.

Ask at your next appointment which name your records use, so that referrals and test requests stay consistent as you move between a GP, a gynaecologist and an endocrinologist. If you are unsure which of those to see, there is a guide on which doctor handles hormonal symptoms.
