Understanding Menstrual Health, PMS, and PMDD
Menstrual health plays a significant role in overall wellbeing — yet it is often overlooked in conversations about mental health. For many, the days before a period bring manageable discomfort. But for others, hormonal changes can trigger emotional and physical symptoms that disrupt daily life.
Premenstrual Syndrome (PMS) can cause irritability, fatigue, and mood swings, while Premenstrual Dysphoric Disorder (PMDD) is a more severe, disabling condition that affects around 3–8% of people who menstruate. PMDD can bring intense depression, anxiety, and even thoughts of self-harm during the luteal phase of the menstrual cycle.
At Hope Therapy & Counselling Services, we offer support for the full spectrum of menstrual health concerns — from mild PMS to life-altering PMDD — with a focus on understanding your individual experience and helping you find relief.
Signs & Symptoms
PMS and PMDD symptoms vary but may include:
Emotional Symptoms:
- Mood swings
- Anxiety
- Irritability or anger
- Low mood or depression
- Feeling overwhelmed
- Loss of interest in activities
Physical Symptoms:
- Fatigue
- Breast tenderness
- Bloating or water retention
- Changes in appetite
- Headaches or migraines
For PMDD, symptoms are more severe, often causing significant disruption to work, relationships, and daily functioning.
Causes of PMS and PMDD
While exact causes are still being studied, these conditions are linked to hormonal fluctuations during the menstrual cycle. Sensitivity to changes in oestrogen and progesterone can influence brain chemicals like serotonin, which regulates mood and emotional balance.
Other contributing factors may include genetics, past trauma, chronic stress, and co-existing mental health conditions.
The Effects on Mental Health and Daily Life
Menstrual-related mood symptoms can impact:
- Work performance – difficulty concentrating, fatigue, and increased absence.
- Relationships – conflict, withdrawal, or communication difficulties.
- Self-esteem – feelings of being “unpredictable” or “too emotional.”
PMDD, in particular, can feel like living two different lives each month, creating cycles of distress and exhaustion.
Treatment and Support
Support may include:
- Lifestyle changes – balanced diet, regular exercise, sleep hygiene.
- Medication – SSRIs, hormonal contraceptives, or other medical treatments.
- Counselling – CBT, mindfulness-based therapy, or interpersonal counselling.
- Self-management – cycle tracking, stress reduction, planning demanding tasks outside the luteal phase.
Why PMDD Feels Harder in Late Autumn
PMDD is a severe, hormone-related mood disorder that occurs in the luteal phase of your menstrual cycle — typically the week or two before your period. It’s thought to result from a heightened sensitivity to normal hormonal fluctuations, particularly oestrogen and progesterone.
As autumn settles in, two things happen that can compound these effects: reduced daylight and increased seasonal stress.
- Less sunlight means less serotonin. Lower light exposure affects serotonin — the neurotransmitter that regulates mood, appetite, and sleep.
- Melatonin increases in darker months. This can cause greater fatigue, sluggishness, and emotional sensitivity.
- Colder weather limits activity. Less movement and time outdoors can worsen low mood and tension.
- Stress builds more easily. End-of-year work pressure, family obligations, and reduced social contact can all intensify PMDD symptoms.
- Sleep disruption. Many experience disturbed sleep patterns, which can worsen irritability and anxiety.
Together, these factors can turn what might be a challenging week into a full emotional storm — especially if PMDD is already affecting your daily life.
