Premenstrual Dysphoric Disorder

Premenstrual dysphoric disorder (PMDD) is a chronic condition that affects a subset of women during their childbearing years. It is a more severe and debilitating form of premenstrual syndrome (PMS), with symptoms that can significantly disrupt daily life, social interactions, and personal relationships. The symptoms of PMDD typically occur during the luteal phase of the menstrual cycle. Understanding the nature and impact of PMDD is crucial for those affected by the condition and their loved ones.

What is Premenstrual Dysphoric Disorder?

PMDD is a depressive disorder (as per DSM-5-TR) characterised by severe affective, behavioural, and physical symptoms occurring during the luteal phase of the menstrual cycle. It affects approximately 5% to 8% of women of reproductive age (Shukla et al., 2025). Unlike PMS, which is relatively common and less severe, PMDD symptoms are more intense and can be highly debilitating. 

It is characterised by intense mood changes, anxiety, depression, and physical symptoms that occur in the week or two before menstruation. These symptoms typically improve within a few days after the onset of menstruation. 

However, they can significantly interfere with a woman's personal and professional life during the symptomatic period. The DSM-5-TR, a widely used manual for mental health disorders, recognises PMDD as a distinct condition. This highlights its significance and the need for proper diagnosis and treatment.

The symptoms of PMDD are more severe and debilitating compared to those of PMS. These symptoms can be classified into emotional and physical categories:

Emotional Symptoms

• Feelings of sadness, hopelessness, or low self-worth
• Heightened anxiety, tension, or a constant sense of unease
• Fluctuations in mood
• Increased self-criticism and sensitivity to rejection
• Occasional or unexpected tearfulness
• Greater irritability or anger
• Conflicts with family, colleagues, or friends
• Reduced interest in usual activities
• Difficulty concentrating
• Feelings of being overwhelmed or lacking control

Physical Symptoms

• Swelling or tenderness in the breasts
• Headaches
• Aches in joints or muscles
• Weight increase
• Bloating
• Changes in appetite, such as continuous eating, overeating, or craving certain foods
• Changes in sleep patterns, such as oversleeping or difficulty sleeping
• Fatigue, lethargy, or lack of energy

PMDD does not have stages; symptoms follow a cyclical pattern linked to the luteal phase of the menstrual cycle (around two weeks before your period) (Premenstrual dysphoric disorder (PMDD). (n.d.)). 

This is the period between ovulation and the start of menstrual bleeding. This phase usually lasts about two weeks, but can be longer or shorter for some individuals. The stages of PMDD are as follows:

• Luteal Phase: Symptoms of PMDD typically appear during this phase and improve within a few days after menstruation starts.
• Symptom Onset: Symptoms usually start 10 to 14 days before menstruation and can last until the first few days of the menstrual period.
• Duration: Symptoms can last throughout the luteal phase and may vary in intensity and duration among individuals.

1. Antidepressants – Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs such as fluoxetine, paroxetine, sertraline, citalopram, and escitalopram are often recommended for managing emotional symptoms of PMDD, like mood swings, irritability, and sadness. They help improve serotonin levels in the brain, which are often disrupted during the premenstrual phase.

• Fluoxetine: Helps reduce irritability, mood swings, and tension during the luteal phase.
• Paroxetine: Often used for severe emotional disturbances such as sudden sadness or anger.
• Sertraline: Shown to reduce depression and anxiety symptoms in PMDD significantly.
• Citalopram: Offers mood regulation benefits with a generally well-tolerated profile.
• Escitalopram: Effective for both continuous and luteal phase-only treatment strategies.

2. Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs)

Duloxetine and venlafaxine may be helpful for women who experience both emotional and physical symptoms, such as fatigue or body aches. These help balance both serotonin and noradrenaline, providing broader symptom relief in PMDD.

• Duloxetine: Reduces both emotional instability and physical pain associated with PMDD.
• Venlafaxine: Particularly helpful for fatigue, body aches, and low energy during premenstrual days.

3. Contraceptives

Certain hormonal birth control options containing ethinyl estradiol + drospirenone can help regulate hormonal fluctuations that worsen PMDD. These contraceptives may ease both physical and emotional symptoms by stabilising estrogen and progesterone levels.

• Ethinyl estradiol + drospirenone: This combination is known to ease mood changes, bloating, and breast tenderness by maintaining steady hormone levels.

4. Vitamins, Minerals and Supplements

Supplements such as calcium, magnesium, vitamin B6, and vitamin E may help alleviate bloating, breast tenderness, and fatigue. Regular intake has been linked with improved premenstrual well-being and may be recommended alongside other treatments.

• Calcium: It helps reduce fatigue, mood changes, and appetite fluctuations.
• Magnesium: It helps ease bloating, water retention, and sleep issues.
• Vitamin B6: It supports neurotransmitter balance and helps with mood stability.
• Vitamin E: It assists in relieving breast pain and other discomforts associated with PMDD.

5. Non-Pharmacological Treatments

Cognitive behavioural therapy (CBT) has proven effective in addressing anxiety, depression, and emotional instability related to PMDD. For physical discomfort such as headaches or joint pain, painkillers or anti-inflammatory medicines like ibuprofen can help with physical symptoms only (e.g., pain, headache). A healthy lifestyle, including a balanced diet, regular exercise, adequate sleep, and stress-reduction methods such as yoga, deep breathing, and meditation, can significantly improve symptoms and overall well-being.

Living with PMDD can be challenging, but various strategies and support systems can help you deal with the symptoms and improve your overall well-being.

• Self-Care: Making dietary changes, such as choosing healthier foods and reducing salt intake, can help manage bloating. Regular physical activity, even gentle exercises like walking or yoga, can help alleviate physical and emotional symptoms. 
  Stress management techniques, including meditation, deep breathing exercises, and counselling, can provide a sense of control and emotional balance.
• Support Systems: Joining support groups, either in-person or online, can be a valuable source of emotional support and understanding. Connecting with others who share similar experiences can help you feel less alone and provide practical tips for managing PMDD. 
  Communicate openly with your loved ones about your condition so that they can offer support and understanding during challenging times.

Remember, living with PMDD is a unique journey for each individual. It's crucial to be patient with yourself, prioritise self-care, and seek professional help when needed. By combining medical treatment, lifestyle modifications, and a strong support network, you can develop effective coping strategies and improve your overall quality of life.

If you suspect that you may have PMDD, it is essential to consult with a healthcare provider for an accurate diagnosis and appropriate treatment. Here are some signs that it's time to seek medical attention:

• Severe Symptoms: If your premenstrual symptoms are severe enough to interfere with your daily life, including your ability to work, study, or maintain relationships, it's crucial to seek medical help. This is especially important if you experience extreme irritability, anxiety, depression, or suicidal thoughts.
• Symptom Tracking: Keeping a symptom journal can help you track your symptoms over one or two menstrual cycles. This information can be valuable to your doctor in making an accurate diagnosis and developing an effective treatment plan.
