Breachers Gut

Gut and brain are tightly linked — a healthy gut supports mood, cognition, immune function, and resilience to stress. The intestinal lining normally acts as a selective barrier: it lets nutrients pass while keeping microbes and inflammatory molecules out. When that barrier becomes more permeable (“leaky gut”), bacterial components and immune triggers can enter the bloodstream, drive systemic inflammation, and disrupt neurotransmitter balance and brain function.

Exposure to overpressure from blasts — common in military and some industrial settings — can physically stress tissues throughout the body, including the gut. Blast overpressure can damage intestinal barriers, increase permeability, and provoke inflammatory cascades that feed into the gut–brain axis. This pathway helps explain why blast-exposed individuals often show not only GI symptoms but also mood changes, cognitive problems, and increased risk of depression and suicide.

Protecting gut integrity after blast exposure is therefore essential for both physical and mental recovery. Strategies include early medical evaluation, reducing inflammation, restoring healthy microbiota, supporting the mucosal barrier, and addressing stress and sleep. Treating gut-brain health as a single system improves outcomes — for digestion, for mood, and for long-term resilience.
