Mood & Psychological

Is mood lability a sign of perimenopause?

Rapid cycle of mood swings within hours or days.

Why it happens

Emotional shifts are frequently the first symptom of perimenopause to appear -- often years before hot flashes. Progesterone plays a key role in calming the nervous system, and its early decline can trigger anxiety and mood instability. Women are routinely misdiagnosed with depression or panic disorder at this stage.

Did you know? Less than 20% of U.S. primary care physicians have received formal menopause training — meaning this symptom is frequently misattributed to stress, anxiety, or ageing.
