Acute vs. Chronic — A Critical Distinction
Inflammation, in its normal function, is a temporary protective response. The immune system detects a threat — tissue damage, a pathogen, a foreign substance — mobilises a response, resolves the threat, and returns to baseline. The entire sequence is self-limiting: the inflammatory signal is designed to switch off when it is no longer needed.
Chronic inflammation is a fundamentally different state. It is characterised by a persistent low-grade inflammatory signal that does not resolve — not because the immune system is failing, but because the conditions generating the signal have not been removed. The immune system is responding appropriately to an ongoing stimulus; the problem is that the stimulus is continuous.
In HS, this distinction is central to understanding why the disease behaves the way it does. The inflammation associated with an HS flare — the acute, visible swelling and pain — is a superimposition on top of a chronic inflammatory baseline that never fully resolves between episodes. Treating the acute flare without addressing the chronic baseline is why HS returns: the fire is temporarily suppressed, but the environment in which it is burning has not changed.
"If it keeps coming back, it means the root cause has not been addressed."
What Generates the Chronic Inflammatory Baseline in HS
The persistent inflammatory state in HS is not generated by a single source. It is the product of multiple interacting systems — each contributing to a baseline that none of them alone would be sufficient to sustain. This is why single-target interventions — addressing only one driver while leaving others intact — produce partial and temporary responses.
The Gut — The Primary Inflammatory Source
Gut dysfunction is the most consistent internal driver of the chronic inflammatory baseline in HS. The gut's role in regulating systemic inflammation is substantial: when gut barrier integrity is compromised, bacterial components and inflammatory metabolites enter the bloodstream through pathways they would not access in a healthy gut. This triggers a persistent immune activation that is not localised to the gut — it affects the entire body, including the skin.
The clinical relevance of this connection is well illustrated by the observation that many HS patients report digestive symptoms — bloating, irregular bowel function, food sensitivities — that their treating physicians regard as unrelated to their skin condition. In most cases, they are expressions of the same gut dysfunction that is sustaining the inflammatory baseline driving HS. Addressing the gut without addressing HS, or addressing HS without addressing the gut, produces incomplete outcomes in both directions.
The gut microbiome — the community of microorganisms inhabiting the digestive tract — also plays a significant role. A dysbiotic microbiome, in which the balance of organisms has shifted toward patterns that sustain inflammation, produces a continuously elevated systemic inflammatory signal. This is a slow process to develop and a slow process to correct — which is why gut-directed intervention in HS requires sustained, structured engagement rather than short-term supplementation.
Hormonal Imbalance — The Amplifier
Hormonal dysregulation does not simply create follicular vulnerability — it also amplifies the inflammatory response at those sites. Androgens modulate immune signalling in the skin: elevated androgen activity increases the inflammatory threshold sensitivity of follicular tissue, meaning that a lesser stimulus generates a greater response. In practical terms, this means that a gut-generated inflammatory signal that would produce only minor skin disruption in a hormonally balanced person produces significant follicular inflammation in someone with androgen excess.
Insulin resistance — which directly sustains androgen excess — adds another layer. Elevated insulin amplifies the production of pro-inflammatory signalling molecules and suppresses the anti-inflammatory regulatory mechanisms that would normally limit the immune response. The resulting environment is one in which inflammatory signals are amplified going in and suppressed going out — a combination that sustains the chronic baseline effectively.
Immune Dysregulation — The Amplified Response
In HS, the immune response to follicular disruption is characteristically disproportionate. When a follicle ruptures in a person without HS, the immune response is contained and resolves within days. In HS, the same event triggers an amplified, prolonged response that causes significantly more tissue damage — creating the conditions for abscess formation, sinus tract development, and the structural changes of progressive disease.
This amplification is not simply an inherent feature of the individual's immune system — it is a consequence of the systemic inflammatory environment in which that immune system is operating. Chronic low-grade inflammation from gut and hormonal sources desensitises the immune system's regulatory mechanisms, reducing the efficiency of the feedback loops that normally limit the scope of the inflammatory response. The immune system is not malfunctioning; it is responding rationally to an environment in which it has been chronically over-stimulated.
In Ayurvedic understanding, the chronic inflammatory state in HS corresponds to a sustained accumulation of Ama — incompletely metabolised material — in the body's channels and tissues. Ama does not resolve spontaneously because the conditions generating it (impaired Agni, or digestive capacity) have not been corrected. The inflammatory expression at the skin surface reflects this deeper internal accumulation. Ayurvedic treatment begins with correcting Agni — not with suppressing the visible inflammation — because the visible inflammation is an effect, not the cause.
Why Anti-Inflammatory Drugs Address the Signal, Not the Source
Anti-inflammatory medications — including steroids, non-steroidal anti-inflammatory drugs, and biologics targeting specific inflammatory molecules — work by interrupting inflammatory signalling pathways. They are effective at reducing the acute inflammatory response and can provide meaningful symptom relief. Their limitation in HS is not that they do not work: it is that they address the signal while leaving the source intact.
When a biologic blocks a specific inflammatory molecule — TNF-alpha, for example — it reduces the intensity of the inflammatory response. But the gut dysfunction generating the systemic inflammatory signal, the hormonal imbalance amplifying the follicular response, and the immune dysregulation perpetuating the cycle all continue operating. When the biologic is discontinued, the inflammatory environment reasserts itself — typically producing a return to previous disease activity or beyond. This pattern is well documented and widely observed; it is the predictable consequence of signal suppression without source correction.
The Self-Sustaining Loop — Why Inflammation Perpetuates Itself
One of the more clinically important features of chronic inflammation in HS is that it becomes, to a degree, self-sustaining. Chronic inflammation causes tissue damage; tissue damage generates further inflammatory signals; those signals sustain the inflammatory state; which causes further tissue damage. This loop explains why HS tends to worsen progressively when uncorrected — not simply because the internal drivers are getting worse, but because the inflammatory process itself is generating new inflammatory material.
The same self-sustaining quality applies at the metabolic level. Chronic inflammation worsens insulin resistance; worsened insulin resistance amplifies androgen production; elevated androgens increase the inflammatory sensitivity of follicular tissue; which produces more inflammation. Each element of the cycle feeds the others.
This self-sustaining quality is also why treatment requires a sequenced approach rather than a single intervention. Breaking one link in the cycle is rarely sufficient — the other links continue to sustain it. Structured treatment addresses multiple links simultaneously and in sequence, reducing the overall inflammatory burden at a pace that allows genuine correction rather than temporary suppression.
What Correcting Chronic Inflammation Actually Requires
Correcting the chronic inflammatory baseline in HS requires identifying and addressing the sources that are generating it — not suppressing the downstream signal. In practice, this means:
Gut restoration — correcting barrier integrity, addressing dysbiotic microbiome patterns, and restoring digestive capacity such that the gut stops generating the persistent inflammatory signal it has been producing. This is a process measured in months, not weeks.
Hormonal correction — addressing androgen excess, insulin resistance, and adrenal dysregulation in a personalised, sequenced manner that corrects the amplification of the inflammatory response rather than simply suppressing it pharmacologically.
Immune regulation — supporting the immune system's own regulatory mechanisms — the feedback loops that normally prevent over-response — rather than blocking specific inflammatory molecules while leaving the regulatory deficit intact.
Systemic stabilisation — sleep, stress management, dietary pattern, and movement: not as lifestyle adjuncts, but as direct modulators of the chronic inflammatory state that are as pharmacologically relevant as any intervention targeted at the skin.
