Brain-gut connection explains why integrative treatments can help relieve digestive ailments
By Michelle Dossett, MD, PhD, MPH
What exactly is the connection between brain and gut? The brain sends signals to the digestive, or gastrointestinal (GI), tract via the sympathetic (“fight or flight”) nervous system and the parasympathetic (“rest and digest”) nervous system. The balance of signals from these two inputs can affect the speed at which food moves through the digestive system, absorption of nutrients, secretion of digestive juices, and level of inflammation in the digestive system.
