Women with irregular periods should be checked for PMOS, NHS says
The NHS has issued new guidance stating that women with irregular periods should be checked for Polyendocrine Metabolic Ovarian Syndrome (PMOS). PMOS is a common condition that can have a significant impact on health and wellbeing, and is often underdiagnosed and inconsistently managed. The new guidance aims to improve consistency of care and increase awareness of the condition, with the goal of supporting earlier diagnosis and management.
- ▪Up to 4 million women with irregular periods should be investigated for PMOS, according to the new NHS guidance.
- ▪PMOS is associated with a greater risk of developing type 2 diabetes, cardiovascular disease, and mental health issues.
- ▪The condition can be more prevalent among black, Asian, and mixed ethnicity women, and healthcare professionals should consider this when assessing symptoms.
