PMS or PMDD? When Period Mood Changes Need Attention
Mood swings, irritability or sadness before your period? The difference between PMS and PMDD, how to track your symptoms, and the treatments that help.
Key takeaways
- Many women have some PMS. PMDD is a more severe form that seriously affects daily life and relationships.
- Symptoms appear in the week or two before a period and ease within a few days after it starts.
- Tracking symptoms for two cycles helps you and your doctor understand what is happening.
"You're just hormonal" is something many women hear when they feel low, irritable or anxious before their period. Premenstrual changes are real, and for some women they are severe enough to disrupt work, studies and relationships every month.
What is PMS?
Premenstrual syndrome (PMS) is a group of physical and emotional changes in the days before a period. Many women have at least some symptoms, such as:
- Mood swings, irritability or feeling tearful
- Bloating, breast tenderness and headaches
- Tiredness and food cravings
- Trouble sleeping or concentrating
For most, these are uncomfortable but manageable.
What is PMDD?
Premenstrual dysphoric disorder (PMDD) is a more severe condition that affects a smaller number of women (roughly 3 to 8 in 100). The emotional symptoms are intense, such as:
- Deep sadness or hopelessness
- Severe anxiety or tension
- Anger and irritability that strains relationships
- Feeling out of control or overwhelmed
- Sometimes thoughts of self-harm
The key pattern: symptoms appear in the week or two before your period and ease within a few days after it starts, with a symptom-free time after.
Why does it happen?
PMDD is not caused by abnormal hormone levels. Instead, some brains appear to be more sensitive to the normal rise and fall of hormones during the cycle, which affects brain chemicals like serotonin. Stress, poor sleep and other mental health conditions can make it worse.
PMDD or something else?
Depression and anxiety can also get worse before a period (called premenstrual exacerbation). The difference is that with PMDD, you feel well for part of the month. Tracking helps tell them apart.
Track your symptoms
For two cycles, note each day how you feel (mood, anxiety, irritability, sleep, physical symptoms) and when your period starts. A simple notebook or app works. Take it to your doctor or therapist.
What helps
- Lifestyle: regular exercise, sleep, less caffeine and alcohol, and steady meals can ease PMS.
- Planning: if you know your difficult days, plan lighter schedules and more rest.
- Talking therapy: CBT can help you manage symptoms and their impact on relationships.
- Medical treatment: for PMDD, doctors may suggest certain antidepressants (sometimes only in the second half of the cycle) or hormonal treatments. A psychiatrist or gynaecologist can explain the options.
