Inflammatory Depression: What’s Really Behind Low Mood in Perimenopause

If you’re in midlife and struggling with mood changes, low energy, brain fog, sadness, or even a sense of emotional flatness... you’re not alone.
And more importantly, you’re not broken.
In fact, what’s often labeled as depression during perimenopause isn’t just in your head—it’s rooted in hormones, inflammation, and nervous system dysregulation.
And, if you have been handed a pill without anyone looking into inflammation, then you are part of the rapidly growing number of women who are being mistreated for their low mood.
In Episode 15 of The Vital Spirit Podcast, I explore what I call inflammatory depression—a physiological condition connected to gut health, hormone shifts, mitochondrial function, and the immune response of the brain itself.
What Is Inflammatory Depression?
Unlike conventional models that reduce depression to a serotonin imbalance, inflammatory depression involves:
Chronic low-grade inflammation
Shifting hormone levels (estrogen, progesterone, cortisol, pregnenolone)
Gut-brain axis disruption
Nervous system dysregulation
Blood sugar imbalances
Environmental and emotional stressors
PET scans even show a slowdown in brain metabolism in midlife women—a process called cerebrohypometabolism—which contributes to memory lapses, fatigue, and flat mood. There are clear physical root causes of low mood, and now we are seeing proof of this in imaging.
The Role of Hormones in Mood
Hormones like estrogen and progesterone play powerful neuroprotective and anti-inflammatory roles. As they fluctuate or decline during perimenopause, women often experience:
Disrupted sleep and circadian rhythms
Decreased serotonin and dopamine signaling
Increased neuroinflammation
Heightened sensitivity to stress and trauma triggers
And yet, many are prescribed SSRIs without ever having hormone or inflammation markers tested. The first thing we do at Roots Deep Medicine and within The Vital Spirit Method is assess how these changes are impacting your mood.
The Inflammation–Mood Connection
When I see midlife women in my practice with symptoms of low mood, I often run labs such as:
hsCRP (high-sensitivity C-reactive protein)
Ferritin
Pregnenolone
B vitamins (B6, B12, folate)
Omega-3 fatty acid levels
Insulin and glucose
A complete thyroid panel including Free T3 and T4
These often reveal underlying inflammation, nutrient deficiencies, or hormonal imbalances that have been overlooked. And there is SO MUCH we can do together to feel better!
Here Are The 6 Root Causes of Inflammatory Depression in Perimenopause I See Most:
Leaky Gut (Intestinal Permeability)
Gut inflammation, dysbiosis (like Candida or SIBO), and food sensitivities can trigger immune activation and mood shifts.
Blood Sugar Dysregulation
Glucose and insulin spikes/crashes can provoke cytokine release and mood swings. Balanced meals = stable mood.
Hormonal Decline
Shifting estrogen and progesterone levels impact neurotransmitters, brain detoxification, and inflammatory control.
Chronic Stress and Nervous System Imbalance
Low vagal tone and trauma history often increase inflammatory signaling and emotional exhaustion.
Environmental Toxins and Mitochondrial Load
A high toxic burden can activate the cell danger response, draining energy and fueling neuroinflammation.
Poor Sleep and Circadian Disruption
Without deep sleep, the brain can’t detox effectively—leading to cognitive fog and emotional instability.
What You Can Do to Heal
My Vital Spirit Method™ supports midlife women by addressing terrain-level healing with personalized, root-cause protocols.
Nutrition & Supplementation
Omega-3s – anti-inflammatory and mood-stabilizing
B-complex vitamins – especially active B6, B12, and folate
Magnesium (glycinate or threonate) – for sleep, stress, and cognition
Pregnenolone – based on labs, supports neurosteroid balance
NAC – especially for OCD or trauma-linked depression
Amino acids & cofactors – tyrosine, taurine, zinc, vitamin C
Herbal Medicine
Saffron, St. John’s Wort, Rhodiola, Ashwagandha
Lemon Balm, Passionflower, Holy Basil, Bacopa
Curcumin – for brain inflammation and mood regulation
Homeopathy
I use remedies like Ignatia, Sepia, Nat mur, Phos ac, Lachesis, and Carcinosin based on emotional themes, constitution, and energetic patterns.
Lifestyle & Nervous System Healing
Safe and Sound Protocol (SSP) – to support vagal tone
Morning sunlight & contrast showers – for circadian health
Grounding, castor oil packs, and movement – to reduce inflammation
Breathwork and mirror work – to restore emotional safety
Case Study: Anne, Age 43 – Reclaiming Her Mood by Addressing the Terrain
Anne came to me feeling like a stranger in her own body. At 43, she was exhausted, foggy, low on motivation, and quietly spiraling into hopelessness. Her doctor had suggested an SSRI, but Anne hesitated.
“I’ve never been depressed before,” she told me. “This doesn’t feel emotional—it feels physical. Like my body is dragging my mind down.”
That distinction was key. This typically is a sign to me that something physical has been missed.
She also reported:
Night sweats and frequent 2–4 AM wakings
Hypoglycemic crashes and sugar cravings
Trouble concentrating in the afternoon
PMS mood swings and vague gut discomfort
Labs showed:
hsCRP of 5.6 (elevated inflammation)
Low ferritin (18)
Deficient B6 and B12
Low pregnenolone
Signs of insulin resistance
Gut inflammation
We began with terrain-focused care, not antidepressants:
An anti-inflammatory, gut-supportive food plan
Omega-3s and magnesium glycinate
Saffron extract
Daily morning light and contrast showers
SSP to support vagal tone
Mirror work and self-compassion practices
Gentle movement
Within 3 weeks, Anne’s energy improved. Her lows softened. By 6 weeks, brain fog lifted, cravings subsided, and she was sleeping deeply. Repeat labs at 3 months showed hsCRP had dropped to 1.9, and her mood was stable.
“It feels like my brain and body are finally on the same page again,” she said.
Anne’s story isn’t unique—but it is a powerful reminder that perimenopausal mood changes aren’t random. They’re rooted in the terrain.
Midlife Mood Is a Message—Not a Diagnosis
Depression in midlife isn’t a character flaw or a chemical imbalance. It’s a signal from the body that something deeper needs tending.
When we address the physiological, emotional, and spiritual roots, true healing becomes possible. You can feel like yourself again. Clearer. Calmer. Stronger.
