Emerging research reveals that HS is not simply just a skin disease. It's a complex condition involving metabolic dysfunction, hormonal imbalances, and chronic inflammation. Understanding these connections opens new doors for effective, root-cause treatment that goes far beyond topical creams and antibiotics.
What is Hidradenitis Suppurativa? Beyond The Skin Symptoms
HS (Hidradenitis Suppurativa) is a chronic inflammatory skin condition affecting approximately 0.4-1% of the population. The condition typically manifests as painful, deep-seated nodules, abscesses, and draining tunnels in intertriginous areas (where skin surfaces touches, rubs, or folds together), such as the armpits, groin, under the breasts, and buttocks.
Here's the frustrating reality: HS often goes undiagnosed for an average of 8-10 years. Many patients are told they simply have "bad acne" or recurrent boils. But HS is fundamentally different. It's an autoinflammatory condition driven by complex immune dysregulation, not a bacterial infection or poor hygiene.
The impact extends far beyond physical discomfort. HS significantly reduces quality of life, affecting everything from clothing choices and physical activity to intimate relationships and mental health. Many individuals with HS also carry a lot of shame. But perhaps most importantly for this discussion, HS is increasingly recognized as a systemic condition with connections to metabolic and hormonal health throughout the body.
The Insulin Resistance Connection: Why Metabolic Health Matters for HS
One of the most robust findings in HS research is the striking connection to insulin resistance. This isn't a minor association. It's a major risk factor that affects many HS patients.
A landmark case-control study found that 43.4% of HS patients have insulin resistance compared to just 16.4% of healthy controls. That's nearly three times the rate. When researchers measured HOMA-IR (a standard marker of insulin resistance), HS patients showed a median value of 2.0 compared to 1.5 in controls.
A 2025 study published in the Journal of Clinical Medicine found even more striking differences: HS patients had significantly higher fasting insulin levels (97.2 vs. 69.0 pmol/L) and HOMA-IR scores (3.47 vs. 2.57) compared to matched controls.
The diabetes risk is equally concerning. Meta-analyses show HS patients have an increased risk of developing diabetes mellitus. Metabolic syndrome, a cluster of conditions including high blood sugar, excess body fat around the waist, and abnormal cholesterol levels also can affect HS patients.
So what's the mechanism? Chronic inflammation creates a vicious cycle with metabolic dysfunction. The term "meta-inflammation" describes this chronic, low-grade inflammatory state associated with metabolic disorders. In HS, the inflammatory process isn't limited to the skin. It manifests systemically, contributing to insulin resistance and impaired glucose regulation.
The connection goes both ways. Insulin resistance promotes inflammation through dysregulated adipokine release and pro-inflammatory cytokine production. Meanwhile, chronic inflammation worsens insulin sensitivity. Breaking this cycle can be key to managing both the metabolic and dermatological aspects of HS.
Sex Hormones and HS: The Androgen-Inflammation Link
If you're a woman with HS, you might’ve noticed patterns that seem tied to your hormonal cycle. The research shows what many patients have long suspected: sex hormones play a significant role in HS.
Clinical studies show that 43-76.7% of female patients experience perimenstrual or premenstrual worsening of their HS symptoms. Postpartum flares affect approximately 60% of women. The condition commonly begins around puberty, when sex hormones first surge. These patterns aren't coincidental.
At the molecular level, researchers have identified increased androgen receptor (AR) expression in HS lesions compared to healthy skin. A 2021 immunohistochemical study found that AR expression in skin tunnels was significantly higher in HS patients, with males showing more extensive continuous patterns while females showed segmental, patchy patterns. This differential expression may explain why some women respond particularly well to anti-androgen therapy.
Pregnancy presents a unique hormonal environment. Research shows mixed effects: some women report improvements in symptoms, some report worsening in symptoms, and some remain stable. The postpartum period, however, is particularly challenging, with about 60% of women experiencing deterioration as hormone levels fluctuate dramatically.
The Inflammation-Metabolism Axis: How HS Drives Systemic Disease
To understand HS fully, we need to look at the bigger picture of how inflammation and metabolism interact throughout the body. This is where the concept of adipokines becomes crucial.
Adipokines are signaling molecules produced by adipose (fat) tissue that act as a link between the immune system and energy metabolism. In healthy individuals, these molecules help regulate inflammation and metabolic function. In HS, this balance is disrupted.
Research shows that HS patients have dysregulated adipokine profiles shifted toward pro-inflammatory states:
Adiponectin, an anti-inflammatory adipokine, is significantly decreased in HS
Resistin, leptin, visfatin, and RBP4 (retinol binding protein 4) are elevated
RBP4 levels correlate positively with disease severity and insulin resistance, independent of BMI
The 2025 MDPI study identified haptoglobin, an acute-phase protein, as another important marker. HS patients with elevated haptoglobin showed significantly worse glycemic control, with higher fasting glucose and HbA1c levels. This suggests that the degree of systemic inflammation directly impacts metabolic function.
At the cellular level, the PI3K/AKT pathway appears to be a key mechanism linking inflammation and insulin resistance. This pathway plays important roles in both metabolic regulation and immune function. Chronic inflammation in HS may disrupt this pathway, contributing to both skin symptoms and metabolic dysfunction.
The cardiovascular implications are significant. HS patients have markedly increased rates of cardiometabolic risk factors. Studies show increased systemic immune-inflammation-based biomarkers, indicating that the inflammatory burden extends well beyond the skin.
A Naturopathic Approach: Addressing the Root Cause of HS
At Etobicoke Naturopathic Clinic, we take an integrated, evidence-based approach to HS that recognizes the interconnected nature of this condition. Our philosophy centres on identifying and addressing root causes rather than merely managing symptoms.
Comprehensive metabolic assessment
We begin with thorough laboratory evaluation to assess metabolic function:
Fasting insulin and glucose to calculate HOMA-IR and identify insulin resistance
HbA1c to evaluate longer-term blood sugar control
Lipid panels to assess cardiovascular risk
Vitamin D levels to identify deficiency
Inflammatory markers like CRP
This data provides objective information about your metabolic status and helps guide treatment priorities.
Hormonal evaluation
For appropriate patients, we assess hormonal status:
Androgen panels including various forms of testosterone, DHEA-S, SHBG
Thyroid function including TSH, free T3, free T4, thyroid peroxidase antibody, and thyroglobulin antibody
Evaluation for PCOS when indicated, as HS patients have an increased risk
Personalized protocols
Based on your specific metabolic and hormonal profile, we develop individualized treatment plans that may include:
Targeted nutritional supplementation (vitamin D, omega-3s, anti-inflammatory botanicals)
Dietary modifications to improve insulin sensitivity and weight management
Lifestyle interventions for stress management and sleep optimization
Coordination with conventional care providers for medication management when appropriate
Integration with conventional care
We believe the best outcomes come from collaborative care. We work alongside your dermatologist and other specialists to ensure all aspects of your health are addressed. This might mean supporting you while you're on conventional therapies, helping manage side effects, or preparing for surgical interventions.
Our root-cause philosophy means we look at the interconnected system (your skin symptoms, metabolic health, hormonal balance, and inflammatory status) as parts of a whole that need to be addressed together for optimal outcomes.
Taking Control of Your HS: Next Steps for Better Health
The research is clear: HS is not just a skin condition. It's a complex, systemic inflammatory disease with deep connections to metabolic and hormonal health. Understanding these connections empowers you to pursue treatments that address underlying mechanisms, not just surface symptoms.
If you're struggling with HS, consider these action steps:
Request metabolic screening from your healthcare provider, including fasting insulin, glucose, and HbA1c

Frequently Asked Questions
What is the connection between hidradenitis suppurativa, insulin resistance, sex hormones, and inflammation?
These four factors are interconnected through complex biological pathways. HS involves chronic inflammation that drives insulin resistance. Sex hormones, particularly androgens, influence HS severity through androgen receptor expression in skin lesions. Insulin resistance worsens inflammation, creating a vicious cycle. Addressing metabolic and hormonal factors can significantly improve HS outcomes.
Can improving insulin resistance help with hidradenitis suppurativa symptoms?
Yes, research suggests a connection between insulin resistance and HS. Studies show conventional therapies for insulin resistance can improve clinical outcomes in 50-72% of HS patients. Weight loss interventions also demonstrate benefits. The mechanism involves reducing systemic inflammation while improving metabolic function.
How do sex hormones affect hidradenitis suppurativa flares in women?
Sex hormones can significantly impact HS and many women report premenstrual worsening of HS. Androgen receptor expression is increased in HS lesions, and elevated testosterone has been documented in some patients. Anti-androgen therapies can be highly effective for some.
What vitamin deficiencies are common in hidradenitis suppurativa patients?
Vitamin D deficiency is common in HS. Research shows HS patients can be more likely to be vitamin D deficient compared to the general population. Given vitamin D's important role in immune regulation and its anti-inflammatory properties, supplementation is a simple, evidence-based intervention that most HS patients should consider.
Is there a link between hidradenitis suppurativa and thyroid problems?
Yes, HS is independently associated with hypothyroidism, with patients having an increased risk compared to controls. Thyroid disease severity also correlates with HS severity.
What dietary approaches may help with hidradenitis suppurativa and inflammation?
Anti-inflammatory dietary patterns, particularly Mediterranean-style eating, may help reduce the systemic inflammation underlying HS. Key principles include minimizing processed foods and added sugars (which worsen insulin resistance), emphasizing omega-3 fatty acids from fish and flax, and consuming plenty of colorful vegetables and phytonutrient-rich foods. Some patients also benefit from identifying and eliminating personal food triggers.
How can a naturopathic doctor help with hidradenitis suppurativa treatment?
Naturopathic Doctors can provide comprehensive metabolic and hormonal assessment, identify root causes, and develop personalized treatment protocols. This includes nutritional supplementation, dietary guidance, lifestyle interventions, and coordination with conventional care providers. The approach focuses on addressing the interconnected factors (insulin resistance, inflammation, hormonal balance) rather than just managing skin symptoms.
