Overview
Premenstrual syndrome is the mix of physical and emotional symptoms that many women get in the days before a period, easing once it starts. It includes mood swings, irritability, bloating, breast tenderness and tiredness, linked to the natural hormone changes of the cycle. For most it is mild, but for some it is severe enough to disrupt work and relationships. Lifestyle measures, and for severe cases medical treatment, can markedly reduce the symptoms.
Symptoms
- Mood swings, irritability or low mood before periods
- Bloating and breast tenderness

When to see a doctor
See a doctor if premenstrual symptoms are severe enough to disrupt your daily life, work or relationships each month.
Causes
