Is PMS common?

Yes. Dr Nick Panay, consultant gynaecologist, estimates that:

• 90 per cent of women experience some changes premenstrually.
• Between 5 and 10 per cent of women – about 800,000 women in the UK – are so severely affected that it dominates their life during this phase of the cycle.
• A further one-third of women experience 'moderate' physical discomfort or psychological ill health.
