Understanding PMDD vs. PMS: A Comprehensive Guide

Understanding PMDD vs. PMS: A Comprehensive Guide


Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder (PMDD) are conditions that many women experience. Both relate to the menstrual cycle, but their severity and impact on daily life can differ vastly. Let's dive deep into understanding these conditions better.

Definition and Symptoms

Premenstrual Syndrome (PMS):

  • It's estimated that up to 75% of women experience PMS to some degree.
  • Symptoms often start 5-10 days before menstruation and usually improve when the period starts.
  • Common physical symptoms include fatigue, bloating, weight gain, breast tenderness, headache, and joint or muscle pain.
  • Emotional symptoms might include mood swings, irritability, depression, crying spells, and social withdrawal.

Premenstrual Dysphoric Disorder (PMDD):

  • PMDD affects between 3-8% of women.
  • Emotional symptoms are particularly intense and can interfere significantly with a woman's daily life.
  • Symptoms can include feelings of sadness or despair, anxiety or tension, moodiness, irritability or anger, and even suicidal thoughts.


The exact cause remains a mystery, but it's believed that the brain's response to hormone changes during the menstrual cycle plays a role.
Lower levels of serotonin, a neurotransmitter, have been linked to both PMS and PMDD.


Professionals rely on symptom patterns. Symptoms must be present in the two weeks before menstruation and improve once menstruation starts.
For PMDD, at least five symptoms, including one mood-related (e.g., depression), must be present.

Differentiating Between PMDD and PMS

Understanding whether you have PMDD or PMS is crucial for effective management and treatment. Here's how to differentiate:

Intensity of Symptoms: The most distinguishing factor is the severity of emotional symptoms.

PMS: While mood swings and irritability can occur, they are usually manageable and don't drastically disrupt daily activities.

PMDD: Emotional symptoms are intense, often leading to feelings of sadness, hopelessness, or even suicidal thoughts. They can interfere significantly with work, school, relationships, and daily activities.

Duration and Timing: Both PMDD and PMS symptoms typically begin in the luteal phase (the two weeks before menstruation) of the menstrual cycle.

PMS: Symptoms usually alleviate with the onset of menstruation or shortly after.

PMDD: Symptoms can persist into menstruation and may not always dissipate as quickly.

Physical Symptoms: Both conditions share physical symptoms like bloating, breast tenderness, and fatigue. While they might be more intense with PMDD, the distinction is more about the accompanying severe emotional symptoms in PMDD.

Disruption to Daily Life: Ask yourself how much the symptoms disrupt your daily life.

PMS: Might cause some discomfort or mood swings but usually doesn't result in missed workdays or significant relationship strains.

PMDD: Can feel debilitating. Women with PMDD often report missing work, avoiding social events, or experiencing strained relationships because of their symptoms.

Track and Monitor: One of the best ways to determine if you have PMDD or PMS is to keep a symptom diary. Document your symptoms daily for at least two menstrual cycles. This can provide clarity on symptom patterns and intensity. Sharing this information with a healthcare professional can aid in an accurate diagnosis.

Treatment Options

Lifestyle Changes: Regular exercise can help alleviate cramping and mood disturbances. Maintaining a balanced diet, reducing caffeine and alcohol intake, and avoiding smoking can also mitigate symptoms.


Pain Relief: Over-the-counter pain relievers like ibuprofen can manage cramps and breast tenderness.

Birth Control Pills: These can sometimes even out hormonal fluctuations that lead to symptoms.

Antidepressants: Especially SSRIs, can treat severe emotional symptoms.

Hormonal Therapies: These can target the hormonal changes associated with both PMDD and PMS.

Alternative Therapies:

Calcium Supplements: Can help with mood and physical symptoms.

Vitamin E & Magnesium: Might reduce PMS symptoms. Always consult a doctor before starting new supplements.

Self-Care Tips

Dietary Recommendations: Increase intake of whole grains, vegetables, and fruits. Avoiding salty foods can minimize bloating and fluid retention.

Relaxation Techniques: Practices like yoga, meditation, and deep-breathing exercises can help reduce stress, which can exacerbate symptoms.

Limit Stimulants: Reduce caffeine and sugar, as they can increase mood swings.

Sleep: Aim for 7-9 hours per night to help regulate mood and reduce fatigue.

Coping Strategies

Journaling: Keeping a record of symptoms can help identify triggers and patterns.

Mindfulness and Meditation: Grounding exercises can provide emotional balance.

Support Network: Connect with friends or groups who understand the challenges.

Stay Active: Physical activity, even a short walk, can alleviate symptoms.

Therapy: Cognitive-behavioral therapy can provide tools and strategies to cope.

Myth Busting

PMS Is an Excuse for Emotional Outbursts: While mood changes can be a symptom, PMS and PMDD are real medical conditions with a variety of symptoms.

Only Women Get PMS: While males don't experience menstrual-related PMS, they can have their hormonal cycles and associated mood fluctuations.

You Can't Have PMS and PMDD: A woman might experience standard PMS symptoms in some cycles and more severe PMDD symptoms in others.

Diet Doesn't Affect PMS or PMDD: While it's not a direct cause, diet can influence symptom severity.

Support and Resources

Local Support Groups: Many communities offer groups where women can share experiences and coping strategies.

Online Communities: Platforms like Reddit and dedicated forums can provide a space for discussion and advice.

Professional Help: Seek out therapists or counselors who specialize in women's health.


While PMDD and PMS can be tough to handle, they're manageable with understanding, support, and the right resources. Remember, every woman's experience is unique. Seeking advice and support tailored to your needs can make a world of difference. Don't be afraid to ask for help!
