The guidelines recommend when to suspect PMOS, how to assess women and how to diagnose the condition.

They also say PMOS should not be discounted in women who have been through the menopause.

PMOS is thought to be more common in women of Black, Asian and mixed ethnicity, and healthcare professionals "should consider this when assessing symptoms", NICE says.

Living with PMOS can have a significant impact on mental health and quality of life too, and the draft guidelines say depression and anxiety are common.

For those planning a pregnancy, advice on weight, diet, nutrition, exercise, sleep and mental health is recommended.

Marie Anne Ledingham, consultant clinical advisor for women's and reproductive health at NICE, said recommending a "simple" annual review was an "important step".

"This new guideline will help improve consistency of care, increase awareness of the condition, and support earlier diagnosis and management."

The draft guideline is open for consultation from 1 July to 11 August 2026, and NICE is inviting feedback from healthcare professionals, patients and the public. NICE expects to publish its final guideline on PMOS in December 2026.
