Why does perimenopause cause menopausal mood changes?

Ovarian hormones vary more unpredictably during perimenopause. At the same time, hot flushes, night sweats, pain, irregular bleeding, and fatigue can reduce resilience. A person may feel unusually irritable, anxious, tearful, overwhelmed, or emotionally flat, sometimes with symptoms that come and go. These experiences can overlap with depression, anxiety, thyroid disease, medication effects, or major life stress, so mood changes should not automatically be attributed to hormones.

Keep a simple diary of mood, sleep, bleeding, hot flushes, medicines, and stressful events to identify patterns. Protect regular sleep, eat consistently, move your body in ways you can sustain, and make room for supportive conversations. A clinician can review physical symptoms, mental health, and treatment choices together. Counselling or other talking therapy may help with coping and emotional strain.

Seek an appointment when mood symptoms last, recur, affect relationships or work, or feel difficult to control. Get urgent help if you feel unsafe, cannot care for yourself, or have thoughts of self-harm. Emergency support is needed for severe confusion, agitation, or a sudden major change in behaviour.

Could my sleep, medicines, thyroid, or another condition be affecting my mood? Which symptoms should I record? What support is available if anxiety or low mood is disrupting daily life?
