John Damianos MD is an internal medicine resident at Yale and a frequent Tweeter on all matters related to gastrointestinal health, the gut-brain axis, and the microbiome.

I invited him to come on this YouTube channel in order to share some of his knowledge about these mysterious conditions and the advances that medical science has recently taken in furthering our understanding of them.

== Covered in this conversation: == (Timestamps next section)

The role of the microbiome in regulating the gut brain axis and the two way feedback process between our central and enteric nervous systems.
- Why doctors commonly favor older tricyclic antidepressants ("neuromodulators") over more modern drugs such as SSRIs and SNRIs
What the drug pipeline and treatment horizon looks like for these conditions
The Rome Foundation's decision to move away from the terminology 'functional' when describing these disorders
"PTSD of the gut" - how physical and mental stressors can create lasting dysfunction and GI syndromes.

== Terminology used:==

DGBI: Disorders of the gut-brain interaction.

Hopefully some good information here for patients and even pracitioners involved in treating these common conditions.
