Effects of emotional state on digestive system

Did you know that 90% of body's happy hormone serotonin is located in the gut. Our brain is marvelously connected to our digestive system through a communication channel known as gut-brain axis. Emotional states of fear, anger or stress can easily slow down digestion by increasing production of acids. But long term stress can also decrease stomach acid. Inflammation is also promoted in the gut with disturbed emotional states.
