A moody gut often accompanies depression -- new study helps explain why

A new study found that a serotonin shortage in the gut can cause constipation, similar to depression, and that treatment increasing serotonin levels may alleviate both conditions. The research suggests that slow-release 5-HTP therapies could treat related brain-gut disorders.
