What does a society become when economic injury no longer stops at the surface of life, but enters the gut, the immune system, and the brain? The microbiome is one of the body’s exposed borders. Industrial food, chronic stress, sleep disruption, antibiotics, pollution, poverty, isolation, and accelerated rhythms pass through it. Mental life is not sealed inside the psyche. It is crossed by microbial metabolites, vagal pathways, endocrine stress responses, immune activation, and the slow biological sedimentation of social conditions. The gut–brain axis operates through immune, neural, endocrine, metabolic, and microbial routes; it is not a metaphor, but a biological infrastructure through which environments become bodily states (Cryan et al., 2019; Kelly et al., 2015).
Dysbiosis matters when it becomes inflammatory. Altered microbial ecology, weakened intestinal barrier function, reduced protective metabolites, and bacterial fragments such as LPS can contribute to systemic immune activation. Neuroinflammation names the passage from peripheral inflammatory pressure to the nervous system: glial activation, cytokine signaling, blood–brain-barrier vulnerability, and altered circuits of mood, fatigue, reward, cognition, and threat detection. Inflammation can also disturb neurotransmitter balance: tryptophan may be diverted away from serotonin toward the kynurenine pathway; dopamine-linked reward and motivation may weaken; glutamate–GABA regulation may become less stable. Pleasure thins, fatigue thickens, threat comes closer, and thought loses clarity (Dantzer et al., 2008; Miller and Raison, 2016).
The spiral begins when economic pressure reorganizes the conditions of the body. Acceleration, ultra-processed diets, work pressure, screen exposure, sleep debt, environmental degradation, chronic uncertainty, and social comparison alter stress hormones, food behavior, gut permeability, microbial ecology, and inflammatory tone. Immune signaling then feeds back into mood: fatigue reduces movement, anhedonia reduces social contact, anxiety increases vigilance, poor sleep amplifies cortisol, cognitive fog weakens self-regulation, and craving pushes the subject toward faster rewards. The cause becomes consequence. The consequence becomes new cause. Stress produces dysbiosis; dysbiosis amplifies inflammatory stress; inflammatory stress darkens mood; darkened mood reorganizes the daily habits that sustain dysbiosis (Sudo et al., 2004; Valles-Colomer et al., 2019; Lane et al., 2024).
This is the mental spiral of the neuroinflammatory subject: not one cause, not one lesion, not one clean pathology, but a circular degradation of ecology, immunity, neurochemistry, and life conduct. The body stores what the economic order displaces. Excess becomes permeability. Speed becomes cortisol. Processed food becomes dysbiosis. Precarity becomes inflammatory tone. Inflammation becomes neurotransmitter disturbance. Neurotransmitter disturbance becomes fatigue, irritability, anhedonia, anxiety, cognitive fog, and withdrawal. Microbial capitalism does not mean that bacteria behave like capital; it means that capital reorganizes the biological conditions in which microbes, immunity, and mental life interact. The brain then becomes one more territory where accumulation leaves its trace.
