What the fuck is PMDD?

Most people who menstruate get some premenstrual symptoms. PMDD is more severe. The emotional symptoms in particular can be intense enough to damage relationships, work and daily functioning.

• Severe mood swings, or sudden sadness and sensitivity to rejection
• Intense irritability, anger, or conflict with other people
• Depressed mood, hopelessness, or self-critical thoughts
• Anxiety, tension, or feeling on edge
• Difficulty concentrating, brain fog
• Fatigue and low energy
• Sleep changes — too much or too little
• Appetite changes or food cravings
• Feeling overwhelmed or out of control
• Physical symptoms such as bloating, breast tenderness, joint or muscle pain, headaches

PMDD symptoms typically appear in the week or two before a period — the luteal phase — and then ease off within a few days after bleeding starts, with a symptom-free stretch afterwards.

That pattern is what separates PMDD from conditions that are present all month. It's also why it can feel like you become a different person on a schedule.

Diagnosis depends heavily on the recurring pattern of symptoms across menstrual cycles. Clinicians usually ask for daily symptom ratings over at least two cycles, and will rule out or consider other conditions such as depression, anxiety, thyroid problems, or the premenstrual worsening of an existing condition.

No one can diagnose PMDD from a website, including this one.

PMDD responds to treatment. Options can include medication, hormonal approaches, psychotherapy such as CBT, and support and lifestyle strategies. What's right depends on the person, and that's a conversation for a qualified healthcare professional.
