General information; not independently clinically reviewed. How we prepare our guides.

Understand PCOS, now called PMOS, and keep useful notes about periods, symptoms and prescribed treatment without relying on restrictive food rules.

A condition name may change while your questions remain much the same: why your periods are irregular, what treatment is for and how to make everyday care manageable.

Start your food and symptom diary

Understanding Polycystic ovary syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is now called polyendocrine metabolic ovarian syndrome (PMOS). It is a hormonal condition that can affect periods, hair growth, skin, fertility and metabolic health. You may see both names in appointment letters or older information. [1]

Care and everyday food decisions

Treatment depends on your symptoms and goals, including menstrual, fertility and metabolic needs. It may involve medicines and support with eating and activity. Ask for an individual plan rather than assuming a special diet or supplement is required. [1]

Keeping a useful personal record

Keep symptom and period notes, prescribed medicines and practical food questions together. Record what changed without using a meal to explain every fluctuation. One Food Forward can help you prepare for review, but cannot assess hormone levels, ovulation or fertility.

Does the new name mean I have a different condition?

The NHS describes PMOS as the condition previously called PCOS. Ask your clinician how the terminology applies to your records; a name change does not replace an individual treatment review. [1]

Keep the details somewhere you can find them

There is no need to tell the whole story at once. Start with today’s meal, a symptom or a few words about how you felt. Those small entries give you something to return to when it is time to talk about your care.

Start your food and symptom diary

One Food Forward organises the information you record. It does not diagnose or treat conditions, monitor emergencies or replace professional medical advice.

Your healthcare team should guide diagnosis, treatment and changes to your diet or medicines.
