For many women, the days leading up to their period can bring on a wave of uncomfortable symptoms – bloating, mood swings, and fatigue. But for some, this experience is far more intense, disrupting their daily lives and relationships. If this sounds familiar, you might be dealing with more than just premenstrual syndrome (PMS). You could have Premenstrual Dysphoric Disorder (PMDD), a more severe and debilitating condition.
This blog post will explore the key differences between PMS and PMDD, and provide a comprehensive guide to understanding and managing this challenging condition.

What is PMDD?
Premenstrual Dysphoric Disorder (PMDD) is a severe, often disabling extension of PMS. While up to 75% of menstruating women experience some form of PMS, PMDD affects a smaller percentage, around 3-8% of women. The key difference lies in the severity of the symptoms, particularly the emotional and psychological ones. PMDD can cause extreme mood shifts that can damage relationships and interfere with your ability to function at work, school, or home.
Symptoms of PMDD
The symptoms of PMDD typically appear in the week or two before your period and start to improve within a few days of your period starting. To be diagnosed with PMDD, you must experience at least five of the following symptoms, with at least one being a significant mood-related symptom:
Mood & Emotional Symptoms:
Feelings of sadness, hopelessness, or even suicidal thoughts
Anxiety, tension, or feeling "on edge"
Extreme mood swings, often with frequent crying
Marked irritability, anger, or increased conflicts with others
Feeling overwhelmed or out of control
Other, Physical & Behavioural Symptoms:
Decreased interest in usual activities (work, school, hobbies)
Fatigue or low energy
Difficulty concentrating
Changes in appetite, such as overeating or specific food cravings
Sleep problems (insomnia or hypersomnia)
Physical symptoms like bloating, breast tenderness, headaches, or joint and muscle pain
Why It Happens
The exact cause of PMDD is not yet fully understood, but it's believed to be a severe reaction to the natural hormone fluctuations that occur during the menstrual cycle. It's not a hormonal imbalance, but rather a sensitivity to these changes. Other contributing factors may include:
Serotonin Levels: The hormonal changes that trigger a menstrual period may also cause a decrease in serotonin, a brain chemical that helps regulate mood, sleep, and appetite.
Genetics: PMDD may run in families.
Stress: High levels of stress can worsen PMDD symptoms.
Past Trauma: Some research suggests a link between a history of trauma and PMDD.
The Impact of PMDD on Daily Life
Living with PMDD can be incredibly challenging. The emotional and physical symptoms can make it difficult to maintain relationships, perform well at work or school, and engage in daily activities. Many women with PMDD report feeling isolated and misunderstood.

Diagnosis
If you think you may have PMDD, it's essential to speak with a healthcare professional. To diagnose PMDD, your doctor will likely:
Discuss your symptoms: They will want to know about the type, severity, and timing of your symptoms.
Ask you to track your symptoms: You will likely be asked to keep a daily record of your symptoms for at least two menstrual cycles to confirm that they are linked to your cycle.
Rule out other conditions: Your doctor may perform tests to rule out other medical conditions that could be causing your symptoms, such as thyroid problems or mood disorders.
Treatment for PMDD
The good news is that there are many effective treatments for PMDD. The best approach is often a combination of lifestyle changes, therapy, and, in some cases, medication.
Lifestyle Changes:
Diet: Eating a balanced diet with plenty of fruits, vegetables, and whole grains can help. Reducing your intake of sugar, salt, caffeine, and alcohol may also make a difference.
Exercise: Regular aerobic exercise, such as brisk walking, jogging, or swimming, can help reduce symptoms of depression, anxiety, and fatigue.
Stress Management: Techniques like yoga, meditation, and mindfulness can help you cope with stress and reduce the severity of your symptoms.
Therapy:
Cognitive Behavioural Therapy (CBT): CBT is a type of therapy that can help you learn to identify and change negative thought patterns and behaviours that may be contributing to your PMDD symptoms.
Medication:
Antidepressants: Selective serotonin reuptake inhibitors (SSRIs) are often the first-line treatment for PMDD.
Contraceptive Pills: Certain types of birth control pills can help regulate your hormones and reduce PMDD symptoms. For some, this is the most desirable treatment.
Other hormonal medications: For treatment resistant cases, specialist care is recommended.
