Inflammation in Perimenopause: Why It Rises (And What To Do About It)
Inflammation in Perimenopause
If symptoms suddenly feel louder — more intense flushes, more aches, more fatigue — inflammation may be part of the picture.
During perimenopause, hormonal shifts can increase low-grade inflammation in the body.
Not dramatic inflammation.
But subtle, systemic inflammation that amplifies symptoms.
What Is Inflammation?
Inflammation is your immune system’s response to stress or threat. In short bursts, it protects you.
But when it becomes chronic and low-grade, it can:
▫️Disrupt hormones
▫️Increase insulin resistance
▫️Affect mood
▫️Disturb sleep
▫️Heighten pain sensitivity
This is sometimes called “inflammaging” — the gradual rise in inflammation with age.
Perimenopause can accelerate this temporarily.
Why Does Perimenopause Increase Inflammation?
Oestrogen has anti-inflammatory properties. As levels fluctuate and decline:
▫️Immune balance shifts
▫️Stress response increases
▫️Cortisol becomes less stable
▫️Gut microbiome diversity may reduce
This creates a more inflammatory internal environment.
How Inflammation Can Worsen Perimenopause Symptoms
1. Hot Flushes & Night Sweats
Inflammation affects the hypothalamus — the brain’s temperature control centre. When inflamed, it becomes more sensitive to small hormonal shifts. Result:
▫️More frequent flushes
▫️More intense temperature swings
2. Anxiety & Mood Swings
Inflammation affects neurotransmitters including:
▫️Serotonin
▫️Dopamine
It can increase irritability, anxiety and low mood.
Chronic inflammation and depression are closely linked in research.
3. Sleep Problems
Inflammatory markers can disrupt:
▫️Deep sleep
▫️Melatonin production
▫️Nervous system calmness
Poor sleep then increases inflammation further.
It becomes a cycle.
4. Joint & Muscle Aches
Many women report new aches during perimenopause.
Lower oestrogen reduces joint lubrication and collagen support.
Inflammation increases pain sensitivity.
5. Fatigue
Inflammation increases cytokines (immune signalling proteins).
These can reduce energy production and increase that heavy, drained feeling.
6. Weight Gain & Belly Fat
Inflammation contributes to:
▫️Insulin resistance
▫️Fat storage around the abdomen
▫️Reduced metabolic flexibility
Chronic stress amplifies this.
What Increases Inflammation During Perimenopause?
Common contributors include:
▫️Poor sleep
▫️Chronic stress
▫️Ultra-processed food
▫️Excess sugar
▫️Sedentary lifestyle
▫️Gut imbalance
▫️Alcohol excess
Midlife often increases stress load — making this more likely.
How to Reduce Inflammation in Perimenopause
Small, consistent changes matter more than extremes.
1. Increase Fibre & Vegetables
Aim for:
▫️Colourful vegetables
▫️Leafy greens
▫️Berries
▫️Cruciferous veg (broccoli, cauliflower)
Fibre supports gut bacteria, which regulate inflammation.
2. Add Omega-3 Fats
Sources include:
▫️Salmon
▫️Sardines
▫️Mackerel
▫️Flaxseed
▫️Chia seeds
Omega-3s help reduce inflammatory signalling.
3. Strength Train & Walk Regularly
Movement reduces:
▫️Insulin resistance
▫️Stress hormone load
I▫️nflammatory markers
Walking daily plus resistance training 2–3 times weekly is powerful.
4. Prioritise Sleep
Deep sleep reduces inflammatory markers.
Without sleep, inflammation rises.
Protecting sleep is anti-inflammatory.
5. Manage Stress Load
Chronic cortisol elevation increases inflammation. Supportive tools:
▫️Breath work
▫️Nature exposure
▫️Boundaries
▫️Reducing overtraining
Calm nervous system = lower inflammation.
6. Support Gut Health
Your gut microbiome regulates immune balance. Support it with:
▫️Fibre
▫️Fermented foods (if tolerated)
▫️Reducing ultra-processed foods
A stable gut lowers systemic inflammation.
7. Stay Hydrated
Mild dehydration increases stress response and inflammatory load.
Consistent water intake matters.
8. Consider HRT (If Appropriate)
Oestrogen has anti-inflammatory properties. For some women, HRT improves:
▫️Joint pain
▫️Sleep
▫️Mood
▫️Flush frequency
This is a medical decision requiring GP discussion.
FAQ Section
Does perimenopause increase inflammation?
Hormonal fluctuations reduce oestrogen’s anti-inflammatory effect, which may increase low-grade inflammation.
Can inflammation worsen hot flushes?
Yes. Inflammation can increase sensitivity in the brain’s temperature regulation centre.
Does inflammation cause weight gain in menopause?
Chronic inflammation contributes to insulin resistance and abdominal fat storage.
Can diet reduce inflammation in perimenopause?
Yes. Fibre, omega-3 fats, stable blood sugar and reduced ultra-processed foods all help.
