The relationship between irritable bowel syndrome, the gut microbiome, and obstructive sleep apnea: the role of the gut-brain axis.

Sleep disruption, especially that resulting from obstructive sleep apnea (OSA) - a widely prevalent sleep disorder - can lead to important systemic repercussions. We raise a subject of current interest, namely the possible relationship between sleep in general, OSA, and irritable bowel syndrome (IBS), an intestinal disease that can be made worse by stressful events. The intermittent hypoxia caused by OSA can induce alterations in the gut microbiota, which can lead to the dysregulation of the gut-brain axis and the worsening of IBS. This may be considered to be a circular relationship, with OSA playing a crucial role in the worsening of bowel symptoms, which in turn have a negative effect on sleep. Thus, based on previous evidence, we suggest that improving sleep quality could be a key to disrupting this relationship of IBS aggravation and OSA.
