Many women notice changes in their mood, stress tolerance or anxiety levels during perimenopause and menopause. Hormonal fluctuations, particularly changes in oestrogen and progesterone, can affect brain chemicals involved in mood regulation, sleep and emotional wellbeing. As a result, some women experience anxiety, irritability, mood swings or reduced resilience to stress during the menopause transition. Understanding anxiety and mood changes in perimenopause and menopause can help women recognise that these symptoms are common and explore ways to support emotional wellbeing during this stage of life.
