Perimenopause symptoms: Your complete guide

If you’ve typed “perimenopause symptoms” into Google at 2am, you’re not alone.

Perimenopause doesn’t come with a tidy checklist. It can show up as:

• Brain fog
• Rage you don’t recognise
• Random dizziness
• Itchy skin
• Bloating
• Night sweats
• Feeling “not quite yourself” …… and a load of other bodily choas!

And because the symptoms can affect your brain, mood, digestion, skin, joints and bladder – it can feel disconnected and confusing.

This guide groups symptoms by body system so you can connect the dots and understand what might be happening

Not everything is “just hormones.”
But a lot of it can be.

Why so many symptoms?

Hormones don’t just control your periods. Oestrogen, progesterone and testosterone influence:

• Brain chemistry
• Temperature regulation
• Sleep
• Collagen production
• Bladder and vaginal tissue
• Joint lubrication
• Fat distribution
• Gut motility

So when they fluctuate (not decline smoothly – fluctuate), multiple systems respond.

That’s why perimenopause can feel like a full-body rollercoaster experience.

Brain and Nervous System

Hormonal shifts affect neurotransmitters like serotonin and GABA. That’s why symptoms often feel psychological or neurological.

Keep an eye on yourself and monitor if your symptoms are mild and intermittent and you can still function day to day. Speak to a GP if:

• Anxiety or low mood is affecting daily life
• You experience severe headaches or neurological changes
• Sleep deprivation is impacting your mental health

Body and Metabolism

These symptoms often creep in gradually and feel like your body is “not responding the way it used to.”

When to watch vs when to see a GP

If your symptoms are mild and manageable and fluctuate with your cycle (if you have one) then just keep a track and monitor whats happening.

Speak to a GP if:

• Fatigue is extreme or persistent
• Weight change is rapid or unexplained
• Joint pain is severe or inflammatory
• Digestive symptoms are ongoing or worsening

Vulvovaginal and Pelvic Health

These symptoms are common — but rarely talked about openly.

• Vaginal Dryness and Discomfort – Oestrogen supports vaginal tissue. As levels shift, dryness and discomfort can occur.
  • →Read about vaginal dryness in menopause

• Bladder Problems – Increased urgency, frequency or mild leakage can develop during this transition.
  • → Learn about bladder changes

• Sex and Relationships – Libido shifts. Discomfort. Emotional changes. It’s not “all in your head.”
  • → Explore sex and relationships in perimenopause

Speak to a GP if:

• Pain during sex persists
• You notice bleeding after sex
• Bladder symptoms are disruptive

Pelvic symptoms are common — but you don’t have to tolerate them.

Skin, Hair and Senses

Hormones influence collagen, oil production and nerve sensitivity.

• Itchy Skin – Sudden itchiness without rash can be linked to oestrogen shifts.
  • → Read about itchy skin during perimenopause

• Hair Changes – Texture, thickness and growth patterns can shift.
  • → Explore hair thinning and changes
    
• Body Odour – Changes in sweat composition can affect scent.

• Migraines – Hormone-triggered sensory sensitivity can worsen headaches.

Is This Normal?

Many perimenopause symptoms are common. But “common” doesn’t mean you should ignore red flags.

Speak to a GP if you experience:

• Very heavy or prolonged bleeding
• Bleeding after sex
• Sudden severe headaches
• Chest pain
• Ongoing dizziness
• Severe depression or anxiety
• Rapid unexplained weight loss

Perimenopause can explain a lot — but it shouldn’t automatically explain everything.

Connecting the dots

If you’re experiencing:

• Brain fog + anxiety + poor sleep
• Bloating + weight redistribution + fatigue
• Vaginal dryness + bladder urgency + lower libido

Those clusters make physiological sense.

You’re not imagining patterns.
Your body systems are interconnected.

Understanding that can shift you from panic to perspective.
