Behavioral Feedback Loops and Kinesiophobia in Hidradenitis Suppurativa: A Macroscopic Network

Hidradenitis suppurativa (HS) is a severe inflammatory dermatosis characterized by profound localized pain. Current pathophysiological models of HS focus primarily on microscopic molecular networks and microbiological dysbiosis. Although the psychosocial and behavioral burdens of the disease are individually well-documented, these factors have not yet been integrated into a single macroscopic feedback model. This self-sustaining system operates across three interacting domains: (1) a biomechanical-metabolic loop, where sustained immobility accelerates the accumulation of visceral adiposity and insulin resistance; (2) a psychosocial-physiological loop, where pain-induced sleep disruption and chronic stress drive neuroendocrine dysregulation and maladaptive coping behaviors; and (3) a socioeconomic loop, where economic instability decreases healthcare security. Consequently, these behavioral, psychological, and socioeconomic burdens feed back into the systemic inflammatory core, perpetuating disease chronicity. Moreover, this review explores kinesiophobia (the anticipatory fear of movement) as a potentially critical and overlooked component of the biomechanical-metabolic feedback loop. Currently, there is a notable absence of primary psychometric data quantifying kinesiophobia in the HS population. Future research should aim to quantify this phenomenon to better establish its prevalence and clinical significance. On a macroscopic level, clinicians should aim to systematically break the broader interconnected behavioral feedback loops through multidisciplinary interventions, including cognitive-behavioral therapy and structured patient education. Ultimately, dismantling these psychological and behavioral barriers may be a critical step to attenuate systemic inflammatory amplification and improve long-term clinical outcomes.
