Overview
Premenstrual dysphoric disorder is a severe form of premenstrual syndrome that causes intense emotional and physical symptoms in the days or weeks before a period. Unlike ordinary PMS, the mood symptoms are severe enough to disrupt relationships, work, and daily life. Symptoms reliably ease once the period begins. It is a recognized medical condition, not simply 'bad PMS', and effective help is available.
Symptoms
- Severe mood swings, irritability, or anger
- Marked anxiety or tension
- Deep low mood or feelings of hopelessness
- Difficulty concentrating
- Fatigue and low energy
- Changes in appetite or sleep
- Breast tenderness, bloating, and aches
- Feeling overwhelmed or out of control
- Symptoms that ease once the period starts
Causes & risk factors
- Abnormal sensitivity to normal hormonal changes in the menstrual cycle
- Effects of hormonal fluctuations on brain chemistry
- Genetic factors
- History of depression, anxiety, or trauma may increase risk
Treatment & self-care
A clinician may ask you to track symptoms across cycles to confirm the pattern, then discuss options that can include approaches to the menstrual cycle, treatments aimed at mood symptoms, and lifestyle measures. PMDD is treatable, and a doctor will help find what works for you. Mental health support is an important part of care for many people.
See a doctor urgently if
- Mood symptoms before your period regularly disrupt your life, work, or relationships
- You feel persistently low, hopeless, or unable to cope
- You have thoughts of harming yourself (seek urgent help immediately)
- Symptoms do not improve with self-care measures
