Some studies showed that stool consistency and constipation were associated with gut microbiome (GM) composition, and enterotype, dysbiosis. Growing evidence indicates the significant role of GM in the homeostatic function of the host body. The GM may regulate multiple neurochemical and neurometabolic pathways. Chronicity of the pain is actively modulated at the molecular to the network level by means of several neurotransmitters. The GM to some extent can affect pain perception %K Gut Microbiome %K Pain Severity %K Stool Form %K Constipation %K Chronic Pain %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6139698/
