Understanding PMDD
What is PMDD?
Many people notice emotional changes before their period, but PMDD–premenstrual dysphoric disorder–is more than mood swings. It's a severe, cyclical condition that can disrupt work, relationships, and daily life.

PMDD isn’t ‘just PMS’
It’s a real, diagnosable condition affecting 1 in 20, driven by biology–not willpower.

What Causes PMDD?
PMDD isn’t just about hormones—it’s about how your body responds to them. People with PMDD have a unique sensitivity to normal hormonal changes, affecting mood, energy, and overall well-being.
The Science Behind It
Hormonal Sensitivity
Normal hormonal levels, but heightened brain response
Genetics Matter
PMDD runs in families, certain gene variations increase vulnerability
Brain Chemistry
Serotonin and GABA alterations affect mood and stress regulation
Inflammation & Stress
Higher inflammation and cortisol levels can worsen symptoms

Brain Chemistry
Hormonal fluctuations impact mood and stress regulation, particularly serotonin and GABA
Inflammation & Stress
Linked to higher inflammation and cortisol levels, which can worsen symptoms

The Luteal Shift: When the Tides Turn
PMDD symptoms tend to hit during the luteal phase–the second half of the menstrual cycle, lasting almost half the cycle.

Why Early vs Late Matters
We break it into two phases because hormonal changes affect emotions differently.
Early Luteal
Rising progesterone → Irritability, lower stress tolerance
Late Luteal
Dropping hormones → Sadness, anxiety, fatigue, emotional overwhelm

Why Early vs Late Matters
We break it into two phases because hormonal changes affect emotions differently.
Early Luteal
Rising progesterone—Irritability, lower stress tolerance
Late Luteal
Dropping hormones—Sadness, anxiety, fatigue, emotional overwhelm
Premenstrual Dysphoric Disorder, or PMDD, is a condition where someone experiences severe mood swings and other symptoms that come and go in a predictable pattern related to their menstrual cycle. These symptoms usually start in the second half of the cycle, just before menstruation begins, and get better a few days after menstruation starts. About 5.5% (1 in 20) of women and people assigned female at birth who are in their childbearing years may have this disorder. PMDD is linked to the menstrual cycle but isn't caused by having too much or too little of any hormone. Instead, it's thought to be due to the brain's strong negative response to the normal changes in the hormones estrogen and progesterone.

PMDD & Relationships
PMDD doesn't just affect you–it affects those around you, and can lead to:
Increased misunderstandings
Heightened conflict
Emotional distance

Our Approach
Luteal Health is for education and support—not medical care. We don’t diagnose, treat, or provide therapy. Always consult a healthcare professional for medical or mental health concerns. If you’re struggling, professional support can help. Talk to a doctor, therapist, or 24/7 confidential crisis line (988) for the care you deserve.
PMDD affects an estimated 1.6%-5% of menstruating individuals, depending on diagnostic criteria. Many go undiagnosed due to symptom overlap with other conditions and general lack of awareness.
