PCOS (Now PMOS): Symptoms, Diagnosis and Lifestyle Habits That Can Help

Polycystic ovary syndrome (PCOS) is a common condition that affects how the ovaries work. The NHS now calls it polyendocrine metabolic ovarian syndrome (PMOS), so you may see either name. There is no cure, but treatment from your GP and lifestyle changes can help with the symptoms. This guide covers the signs to look out for, how it is diagnosed in the UK, and the everyday habits the NHS recommends.

Why the name changed

The NHS now uses the name polyendocrine metabolic ovarian syndrome (PMOS). The new name reflects that the condition involves several hormones and the body's metabolism, not just the ovaries. Many people, websites and support groups still say PCOS, and both names describe the same condition.

Common symptoms

Symptoms usually start at puberty and can continue until the menopause. According to the NHS, they can include:

• Irregular periods, or long gaps between periods
• Excess hair growth on the face or body, or thinning hair on the head
• Weight gain or difficulty losing weight
• Oily skin or acne
• Feeling very tired
• Difficulty getting pregnant
• Low mood, depression or anxiety

Not everyone has all of these, and many of them have other possible causes. That is why getting a proper diagnosis matters.

What causes it?

The exact cause is unknown. It may be linked to hormones such as insulin and testosterone not working properly, and it can run in families.

How it is diagnosed in the UK

See a GP if you think you might have PCOS (PMOS), or if your symptoms are affecting your everyday life, work or relationships. A GP may arrange blood tests and an ultrasound scan, and may refer you to a specialist such as a gynaecologist or endocrinologist.

A lifestyle assessment or coaching service, including ours, cannot diagnose PCOS. Always start with your GP.

Lifestyle habits the NHS recommends

The NHS lists several things you can do to help with symptoms:

• Eat a healthy, balanced diet
• Exercise regularly
• Try to lose weight if you are overweight
• Try talking therapy if some symptoms are causing depression or anxiety

In practice, that can mean building meals around protein, vegetables and high-fibre carbohydrates, finding movement you enjoy, such as walking, strength training or Pilates, and keeping a regular sleep routine. Small, steady changes are easier to keep up than strict diets. The free NHS Better Health tools can help you get started.

Why regular check-ups matter

PCOS (PMOS) can increase the risk of some longer-term conditions, including type 2 diabetes, high blood pressure and heart disease. The NHS advises regular check-ups, and healthy habits can help lower these risks. Your GP can tell you which checks you need and how often.

Lifestyle coaching alongside your GP's care

HormoFlow is a lifestyle coaching service. We do not diagnose or treat PCOS (PMOS). If you have a diagnosis and want structured, practical support to stick with the eating, movement and sleep habits your GP has recommended, our coaches can help you fit them around your working day.
