What is premenstrual dysphoric disorder (PMDD)?

Premenstrual dysphoric disorder (PMDD) is a serious form of premenstrual syndrome that affects both mood and physical health. It is linked to the hormonal changes that happen during the menstrual cycle.

Unlike typical PMS, PMDD symptoms are intense and can make it difficult to function at work, at home, or in relationships.

What causes PMDD?

The exact cause isn’t fully understood. Experts believe it’s related to how the brain responds to normal hormone changes during the menstrual cycle. Changes in serotonin, a chemical that affects mood, may also play a role.

Risk factors include:

• Personal or family history of depression or anxiety
• Family history of PMS or PMDD
• Smoking

Symptoms

PMDD symptoms usually appear in the week before your period and improve shortly after it begins.

Common symptoms include:

• Mood swings, irritability, or anger
• Depression or feelings of hopelessness
• Anxiety or feeling overwhelmed
• Trouble concentrating
• Low energy or fatigue
• Difficulty sleeping
• Bloating or weight changes
• Breast tenderness
• Headaches or body aches
• Changes in appetite or food cravings

These symptoms can be severe enough to disrupt daily life.

How is it diagnosed?

There isn’t a single test for PMDD. Your provider will focus on understanding your symptoms and how they follow your menstrual cycle.

Diagnosis typically includes:

• Reviewing your health history
• Tracking symptoms over at least two cycles
• Physical and pelvic exams
• Screening for other conditions like thyroid disorders or mood disorders

A diagnosis is made when symptoms are consistent, cycle-related, and significantly affect daily functioning.

How is it treated?

Treatment for PMDD focuses on reducing symptoms and improving quality of life. Most care plans begin with simple, noninvasive steps and progress if needed.

Lifestyle approaches may include:

• Eating a balanced diet and limiting caffeine, sugar, and alcohol
• Staying physically active
• Managing stress through relaxation techniques
• Nutritional supplements such as calcium or vitamin B6
• Medications like antidepressants (SSRIs), which can help regulate mood
• Hormonal birth control to stabilize hormone changes
• Pain relievers for physical discomfort

PMDD is a long-term condition, but symptoms can be effectively managed with the right care. Treatment may be adjusted over time based on your needs.
