Premenstrual dysphoric disorder

PMDD

Chronic condition

PMDD causes severe mood and physical symptoms in the 1 to 2 weeks before a period. They improve soon after bleeding starts and disrupt work or relationships. It's a real, treatable medical condition, and more than bad PMS.

What happens

Hormone levels are typically normal in PMDD. The current thinking is that the brain is unusually sensitive to the normal shifts in estrogen and progesterone during the cycle, and that serotonin is involved. Timing is the defining pattern: symptoms come on in the week or two before your period, ease within a few days of it starting, and are minimal or gone in the week after it. This sets PMDD apart from depression or anxiety that worsens before a period, where symptoms persist through the rest of the month.

Who gets it

PMDD affects about 1 in 20 women of reproductive age. It can begin any time after periods start. Risk is higher with a personal or family history of depression, anxiety, or postpartum depression, and with past trauma or high stress.

Signs worth getting checked

  • Marked mood swings
  • Irritability or anger
  • Depressed mood or hopelessness
  • Anxiety or feeling on edge
  • Losing interest in things you usually enjoy
  • Trouble concentrating
  • Fatigue or low energy
  • Appetite changes or food cravings
  • Sleeping too much or too little
  • Feeling overwhelmed or out of control
  • Breast tenderness, bloating, joint or muscle aches, or headaches

Labs to ask about

  • There's no blood test for PMDD. Diagnosis rests on a daily symptom diary over at least 2 cycles, such as the Daily Record of Severity of Problems.
  • TSH, since thyroid symptoms overlap
  • CBC and ferritin, to check for anemia and low iron
  • A pregnancy test, if relevant
  • Screening for depression and anxiety

Treatments your doctor may discuss

  • SSRIs (fluoxetine, sertraline, or paroxetine CR), taken daily or only in the 2 weeks before your period
  • Certain birth control pills containing drospirenone, taken with a shortened or skipped hormone-free interval
  • Cognitive behavioral therapy (CBT)
  • For severe cases that don't respond, specialist-guided ovarian suppression with a GnRH agonist plus add-back hormones
  • Removal of the ovaries, a rare last resort

Supportive steps to discuss with your provider

  • Track your symptoms daily to show the pattern.
  • Plan around your difficult days when you can.
  • Protect your sleep, move regularly, and eat regular meals.
  • Some studies support calcium for PMS symptoms. Ask what fits you.
  • Tell people close to you what to expect.

See a doctor promptly if you have

  • Thoughts of suicide or harming yourself: call or text 988, or call 911 if you're in immediate danger
  • Symptoms that disrupt work, school, or relationships
  • Symptoms that don't lift after your period starts
  • Symptoms that began or worsened after starting or changing hormonal birth control or an antidepressant. Don't stop an antidepressant suddenly; call your provider first
