Gut Dysbiosis

Lower Lactobacillus and Bifidobacterium levels are the most consistent microbiome finding in anxiety and depression. Gut microbes may influence susceptibility to neurological disorder progression. Dysbiosis can disrupt neurotransmitter production and trigger chronic low-grade inflammation. A healthy gut microbiome is said to require at least 85% beneficial bacteria to avoid dysbiosis. Gut dysbiosis is consistently associated with anxiety and depression. Gut dysbiosis has been associated with gut-brain axis dysfunction and neurodegeneration. Reduced Faecalibacterium prausnitzii can lower SCFA production and increase depression risk. Antibiotics and poor nutrition can compromise gut microbiome balance and promote leaky gut. Chronic stress is described as a major neglected driver of gut dysbiosis. Dysbiosis is described as triggering risk across cardiovascular, metabolic, gastrointestinal, and autoimmune disease categories. Intestinal dysbiosis is linked to the pathogenesis of neurodevelopmental and neurological disorders. Inflammatory bowel disease is presented as a gut-to-heart risk signal even without classical cardiovascular risk factors. The Standard American Diet is identified…
