What is PMDD? Understanding premenstrual dysphoric disorder and its impact on mental health

Let’s get one thing straight: PMDD is not the same as PMS. While many people experience premenstrual syndrome (PMS) in the days leading up to their period, Premenstrual Dysphoric Disorder (PMDD) is a much more severe condition that affects both physical and mental health and it deserves proper recognition and support.

Despite affecting up to 10% of menstruating people, PMDD is still widely misunderstood. Here’s your guide to what PMDD is, how it differs from PMS, and how to manage its symptoms with compassion and care.

What is PMDD?

Premenstrual Dysphoric Disorder (PMDD) is a chronic, hormone-related mood disorder that occurs in the luteal phase of the menstrual cycle, typically the week or two before your period starts. Unlike PMS, PMDD can cause debilitating emotional and physical symptoms that interfere with daily life, relationships, and mental well-being. It’s not just feeling a bit off before your period. PMDD can make it difficult to work, socialize, or even get out of bed. That’s why awareness, diagnosis, and support are so crucial.

What causes PMDD?

PMDD is classified as an endocrine disorder, meaning it’s rooted in hormonal fluctuations. While the exact cause is still being researched, most experts agree that PMDD is linked to hypersensitivity to normal hormonal changes, especially the drop in estrogen and serotonin after ovulation.

Some studies suggest that genetics, trauma, or chronic stress may also play a role in triggering PMDD. But the truth is, we still have a lot to learn and that’s why open conversations and continued research are so important.

PMDD symptoms: emotional, physical & behavioral

PMDD symptoms vary from person to person, but they tend to be intense, cyclical, and disruptive. Here’s a breakdown of common signs:

Emotional Symptoms

Severe mood swings;
Irritability or anger;
Anxiety and overwhelm;
Depression;
Suicidal thoughts or ideation.

Physical Symptoms

Breast tenderness;
Headaches or migraines;
Muscle and joint pain;
Fatigue and lethargy;
Cramping and bloating;
Panic attacks.

Behavioral Symptoms

Food cravings or binge eating;
Withdrawal from relationships or hobbies;
Sleep disturbances;
Difficulty concentrating.

If you think you may have PMDD, there are a few things you can do to help you understand your symptoms better and advocate for yourself when you go to the doctors.

Also note: PMDD symptoms typically appear only during the luteal phase of your cycle - that’s the time between ovulation and your period. If you’re feeling this way all month long, it could point to a different mental health condition. In that case, it’s important to talk to a healthcare provider who can help you explore what’s really going on and guide you toward the right support.

How is PMDD diagnosed?

Getting a diagnosis can be challenging. PMDD is still under-recognized, and many people are dismissed or misdiagnosed, especially when period-related symptoms are normalized or minimized.

Here’s how to advocate for yourself:

Track your cycle

Keep a detailed record of your symptoms for at least three consecutive cycles. Use a period tracking app or a journal to note emotional, physical, and behavioral changes.

Bring resources to your appointment

Print or bookmark PMDD guidelines from trusted sources like:

National Institute for Health and Care Excellence (NICE);
National Association for Premenstrual Syndrome (NAPS);
Royal College of Obstetricians & Gynecologists (RCOG).

Ask for a referral

Request a referral to a gynecologist or mental health specialist familiar with PMDD. They may offer more nuanced support and treatment options.

Managing PMDD: Holistic support strategies

While PMDD currently has no cure, many people find relief through a combination of medical treatment, lifestyle adjustments, and self-care. Here are some holistic ways to support your mental health during your cycle:

Know your cycle

Understanding your luteal phase can help you plan ahead. If you know this is a time of low energy or emotional sensitivity, avoid high-stress commitments and schedule gentle, supportive activities instead, like cozy nights in or low-key meetups with trusted friends.

Prioritize rest

PMDD can disrupt sleep, so give yourself permission to rest. Take naps, go to bed early, and allow yourself slow mornings when needed. Practices like meditation, breathwork, or gentle yoga can also help regulate your nervous system.

Nourish your body

Support your mood and energy with nutrient-rich foods. Focus on:

Omega-3 and Omega-6 fatty acids (e.g. salmon, flaxseed, walnuts);
Low-sugar meals to stabilize blood sugar;
Whole grains, leafy greens, and magnesium-rich foods.

Movement can also help. Even a short walk or stretching session can boost serotonin and ease tension.

PMDD is real. It’s painful. And it’s often invisible. But with awareness, empathy, and the right tools, people who menstruate can feel more empowered and supported in their journey.
