I read many times and heard from doctors that guts are our "second brain" . I wonder what anus "represents"

and I am pretty sure that guys have a "third brain" too
Pinky -

- hope all will settle down pretty soon and that you will be able to travel with no problems. My poop tends to get loose if I am too stressed. I got loose poop before I even started my colonoscopy prep

. I ended up going 4 times even before I started Golitely thing !!!
So, yes, our emotions have tremendous impact on our GI - that is why we call those feelings like "butterflies in my stomach", or ask " do you have guts" to do it !

Intestinal Serotonin in Irritable Bowel Syndrome and Dyspepsia
ROCHESTER, MN, May 21, 2007-- Serotonin is a neurotransmitter that helps regulate intestinal functions. Mayo Clinic researchers set out to determine the role of serotonin in patients with IBS and dyspepsia. The study involved 48 females -- including individuals with IBS, individuals with dyspepsia, individuals with both IBS and dyspepsia, and healthy volunteers. Biopsies were obtained from the stomach and intestines of each patient and serotonin levels were measured. Researchers found that patients with dyspepsia had low levels of a serotonin reuptake transporter in their stomachs and high levels of a molecule that synthesizes serotonin in the small intestine.
"The results support the concept that functional disorders may be associated with altered serotonin signaling in different regions of the gut. If the data can be validated, it suggests it may someday be possible to make a diagnosis of functional disease by taking a biopsy," says Amy Foxx-Orenstein, D.O., a Mayo Clinic gastroenterologist and lead author of this study. "Mucosal markers for functional disorders might lead to earlier diagnosis and treatment, but further studies are needed."
