[Relationship between functional constipation and brain-gut-microbiota axis].

Although with the higher prevalence, the overall treatment result of functional constipation is still not satisfied at home and abroad. The diagnosis and treatment of functional constipation are still to focus on colon itself. Functional constipation has complex interactions among intestinal flora, intestinal autonomic nerve and central nervous system. Patients with functional constipation have different degrees of mental and psychological dysfunction, and abnormal brain function can result in disorders of colon dynamics, secretion and immune function. At the same time, there is a significant imbalance of intestinal flora in patients with functional constipation. Intestinal flora plays an important role in the release of neurotransmitter and the activity of hypothalamic-pituitary-adrenal axis (HPA axis). Intestinal flora is an important regulator of development, maturity and activity of central nervous system. Therefore, the interaction in the brain-gut-microbiota axis may provide a broader strategy for the diagnosis and treatment of functional constipation and neuropsychiatric disorder.
