Gut-brain communication: How the stomach and brain communicate
Ms Madeleine Di Natale, Professor John Furness
The stomach is the portal to the digestive tract.
The stomach tells the brain about its state: How full it is, what is the nature of its contents, are any toxins present. The brain reacts by eliciting feelings of hunger, satiety, fullness, nausea or wellness. In turn, the brain tells the stomach what to do, after integrating information coming from the stomach and other information, including the sight, smell and proximity of food. For example, the brain can tell the stomach to increase volume to receive food, to mix food, to secrete acid or expel contents.
Miscommunications can lead to changed and dysfunctional motility patterns which can cause severe pain and discomfort to patients with these disorders. We are investigating this two way communication that is essential to a healthy life.
