Perimenopause and Mood Changes
The years before menopause can bring unexpected mood swings, anxiety, and emotional upheaval.
What Is Perimenopause?
Perimenopause is the transitional period leading up to menopause, often beginning in the early to mid-40s but sometimes earlier.
During perimenopause, oestrogen levels fluctuate unpredictably, causing a wide range of physical and emotional symptoms.
Many women don't realise they're in perimenopause, attributing symptoms to stress, ageing, or mental health conditions.
Understanding that hormones may be driving your mood changes can be both validating and empowering.
Mood Symptoms of Perimenopause
Sudden onset anxiety or worsening of existing anxiety.
Depression that doesn't respond to usual coping strategies.
Irritability and rage that feel disproportionate.
Mood swings that change rapidly throughout the day.
Tearfulness and emotional sensitivity.
Loss of joy in activities you previously enjoyed.
Feeling overwhelmed by things you used to manage easily.
Why Perimenopause Affects Mood
Oestrogen fluctuations directly affect serotonin and other mood-regulating neurotransmitters.
Progesterone, which has calming effects, also declines during perimenopause.
Sleep disruption from night sweats and hormonal changes worsens mood.
Perimenopause often coincides with stressful life events, compounding the impact.
The unpredictability of symptoms creates additional anxiety.
