Guillain-Barre Syndrome (GBS) and gut dysbiosis are believed to be linked through the immune system. Gut dysbiosis refers to an imbalance in the gut microbiome, which plays a critical role in immune function. Some studies suggest that an altered gut microbiome may trigger autoimmune responses, potentially leading to GBS. It is hypothesized that infections, particularly viral or bacterial, may disrupt the gut microbiota, which in turn could trigger an immune response that mistakenly attacks the peripheral nervous system, causing GBS. Though the exact mechanism is still being researched, maintaining a healthy gut microbiome through a balanced diet and probiotics may help support immune regulation and potentially reduce the risk of autoimmune diseases like GBS.
