Metabolomics Insights into Gut Microbiota and Functional Constipation

Area of Science:

• Gastroenterology and Microbial Metabolomics
• Integrative analysis of gut microbiota and host physiology

Background:

• Gut microbiota composition and metabolic activity are integral to chronic constipation.
• Microbial metabolites, including SCFAs, bile acids, and neurotransmitters, critically regulate intestinal function.

Purpose of the Study:

• To systematically review and consolidate current literature on microbial metabolomics in chronic constipation.
• To examine how metabolomic insights can improve diagnostics and guide personalized treatments for constipation.

Main Methods:

• Systematic literature analysis of microbial metabolomics in chronic constipation.
• Consolidation of findings from high-throughput metabolomic techniques (GC-MS, LC-MS, NMR).
• Comparative analysis of metabolic profiles between constipated patients and healthy individuals.

Main Results:

• Reduced levels of short-chain fatty acids (SCFAs) are linked to impaired intestinal motility and inflammation.
• Altered bile acid metabolism, specifically decreased secondary bile acids, disrupts signaling pathways affecting motility.
• Imbalances in amino acid metabolism, neurotransmitter production, and microbial gas variations contribute to gut dysfunction.

Conclusions:

• Integrating metabolomics with gut microbiota research elucidates the role of microbial metabolites in gut function regulation.
• Metabolomic insights provide a foundation for developing precision diagnostics and targeted therapies for chronic constipation.
• Restoring microbial balance through metabolomic understanding offers promising avenues for improving intestinal motility.
