FAB RESEARCH COMMENT:
Only in the last 10-15 years has evidence been emerging to show that our gut microbiota appear to play a fundamental role in almost every aspect of health and disease - including brain development and functioning, and therefore mental health and welbeing.
The so-called microbiota-gut-brain axis is highly complex, involving multiple signalling pathways that work in both directions, i.e. from gut to brain, and from brain to gut.
Research has shown that many common medications in addition to antibiotics can disrupt gut microbial balance and diversity - including non-steroidal anti-inflammatories, drugs used to manage diabetes or acid reflux, and some psychiatric medications. See:
This article reviews recent evidence on how medications for mental health disorders - collectively known as 'psychotropics' - may influence the gut microbiota, and conversely, how the balance of gut microbes may influence the action of these medications.
