Hormones, Mood and Mental Wellbeing: Navigating Perimenopause and Menopause (Part 1).
Understanding Hormone-responsive mental health in perimenopause and menopause
Let’s start by clearing something up right away: your brain and hormones are having a serious conversation right now and it’s affecting your mood.
If you’re reading this and feeling like your emotional weather has gone from sunny to unpredictable thunderstorms, you’re not alone - and it’s definitely not ‘just in your head’.
what are perimenopause and menopause really?
First, a bit of a biological context:
Perimenopause is the transition period leading up to menopause. Hormone levels (especially oestrogen and progesterone) can swing wildly - from moment to moment - for years before periods fully stop.
Menopause is defined as the point when you haven’t had a period for 12 consecutive months. Hormone levels settle at a new baseline - much lower than before.
It’s not just about hot flushes and night sweats (although they are real- and annoying). Hormones directly affect your brain - influencing mood, sleep, memory and emotional regulation.
🧠 Exhaustion, irritability, feeling overwhelmed, sudden tears, deep sadness or just ‘not feeling like yourself’ are common during this transition. Some studies even show that women in perimenopause have significantly higher risk of depression compared with premenopausal women.
🧠 Why Hormonal Fluctuations Affect Mood
Here’s the brain science (in plain English):
Your brain has oestrogen receptors. Oestrogen interacts with neurotransmitters - like serotonin and dopamine - that help regulate mood and motivation. When oestrogen dips or fluctuates unpredictably:
Mood regulation becomes harder
Sleep can go wonky (poor sleep worsens mood)
Anxiety or stress responses can feel amplified
‘Brain fog’ - forgetfulness and slower thinking - can peak
Some women describe this hormonal emotional shifting as similar to PMS but more intense and longer lasting, without the regular cycle to track it.
is it normal or clinical?
Great question. Not all mood changes mean a mental health disorder - but they are real and rooted in biology.
Feelings like:
Emotional volatility
Low energy
Irritable outbursts
Sudden anxiety spikes
Can all stem from hormone changes but that doesn’t mean you have to ‘just cope’.
It’s helpful to track symptoms over a week or two - and notice patterns - so you can talk with your doctor or therapist in specifics. Always good to go in prepared.
common mental health symptoms during perimenopause and menopause
During this life transition women often report:
Mood swings and rapid emotional shifts
Anxiety or nervousness
Tearfulness or feeling low for no apparent reason
Difficulty concentrating (brain fog)
Low motivation or energy
Sleep disturbances
Increasingly intense reactions to stress
This isn’t just anecdotal - research into hormonal influence shows clear links between oestrogen fluctuations and affective symptoms.
how this connects with earlier hormonal transitions - pregnancy and postpartum
If you’re thinking ‘Oh wow I remember feeling like that after my baby was born’ - you’re onto something.
Postpartum hormone shifts - particularly the sudden drop in oestrogen and progesterone after birth are among the strongest natural triggers of mood disruption in a woman’s life cycle.
Many women who had postpartum depression, antenatal anxiety or sensitive mood swings with PMS notice those vulnerabilities resurfacing or intensifying during perimenopause. This makes sense because both periods involve significant hormonal restructuring.
Think of it like your hormonal systems emotional volume dial being turned up - except now the dial swings unpredictably.
so what can you do right now?
Let’s break this into parts:
Awareness and validation - just knowing this is a hormone linked phase can be a huge relief. You’re not ‘crazy’ or overreacting.
Track your symptoms - Write down mood, sleep, stressors and physical symptoms over several weeks. This helps with clarity and confidence when talking to professionals.
Lifestyle factors matter - All of the following will help to stabilize mood:
regular sleep rhythm
balanced diet and hydration
gentle movement and walks
connection with friends or support groups
mindfulness or stress-reduction practices
Even small shifts here can make a big difference.
when to seek professional support
If mood symptoms:
last more than two weeks in a row
interfere with daily life or relationships
feel more intense than usual for you
involve thoughts of self-harm
It’s time to reach out to someone - an understanding GP, hormone specialist or therapist, sooner rather than later.
