What it is
PMDD is a severe form of premenstrual symptoms that significantly affects mood, energy, and daily life. Symptoms appear in the week or two before a period and improve within a few days after it starts. PMDD is different from typical PMS and from depression/anxiety that occur all month.
Common symptoms
- Mood: marked irritability, anger, sadness, tearfulness, mood swings
- Mind/body: anxiety, tension, brain fog, low energy
- Physical: bloating, breast tenderness, appetite/sleep changes, headaches, joint/muscle pain
- Impact: conflict at home/work, missed activities, reduced functioning
Patterns matter: tracking cycles helps confirm that symptoms cluster premenstrually and remit after onset of period.
Why it happens
- Sensitivity to normal hormonal changes across the menstrual cycle (not “too much” hormone, but heightened brain sensitivity)
- Stress, sleep disruption, and underlying depression/anxiety can worsen symptoms
- Thyroid, iron deficiency, or other medical issues can contribute to fatigue—worth checking
What helps right now
- Symptom tracking: use a daily log for 2–3 cycles to confirm timing
- Sleep and light: consistent sleep; morning light exposure can improve energy and mood
- Movement and nutrition: regular activity; steady meals with complex carbs; reduce alcohol
- Targeted supplements (discuss with clinician): calcium (1,000–1,200 mg/day), vitamin B6 (≤100 mg/day), magnesium (dose varies)
- Stress tools: brief breathing exercises; schedule lighter workloads in the most symptomatic days where possible
Evidence-based treatments
- First-line:
- SSRIs (e.g., fluoxetine, sertraline, escitalopram) taken daily or only during the luteal phase (the two weeks before a period) can be very effective
- CBT for mood regulation, stress management, and planning around symptom windows
- Hormonal strategies:
- Combined oral contraceptives (especially those with drospirenone) may help; continuous dosing can smooth hormonal fluctuations
- In severe, refractory cases, GnRH analogs under specialist care
- Address co-occurring conditions:
- Treat coexisting depression/anxiety; screen for thyroid and iron deficiency
- Lifestyle supports:
- Regular exercise, sleep routine, caffeine moderation, social support
When to seek help now
- Severe mood swings with risk to relationships or work
- Thoughts of self-harm or not wanting to live (seek urgent help)
- Symptoms that persist all month long (may indicate another condition; get evaluated)
How to talk to a clinician
- “I have severe mood and energy symptoms in the 1–2 weeks before my period that improve after it starts. I’ve tracked two cycles. I’d like to discuss SSRI options (daily or luteal phase), CBT, and whether a contraceptive might help.”
Outlook
With cycle tracking, targeted treatments, and support, most people see substantial relief within 1–2 cycles of treatment changes.
