Night work disrupts body clock and changes gut bacteria linked to higher risk of metabolism and digestive problems

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

The relative abundances of Bacteroidetes were reduced and those of Actinobacteria and Firmicutes increased when comparing night shift work to day shift work.

  • Fecal samples from 10 male security officers were analyzed after both day and night shifts.
  • A total of 20 stool samples were collected and analyzed for gut microbiota composition.
  • Changes in gut microbiota were observed, with specific bacteria linked to different shift types.
  • Rotational shift work is associated with disturbances in circadian rhythms.
  • Alterations in gut microbiota may be linked to an increased risk of metabolic syndrome and gastrointestinal issues.
