There are of course many contributing factors for mood swings, however perhaps somewhat a little disregarded and yet to be fully realised, is the stomach is very much a second brain. The alimentary canal, a 9 metre wall, we find some 500+ million neurons, more than the spinal chord and central nervous system. Embedded within this wall you find the Enteric Nervous System which operates independently and in conjunction with the brain between the ears :thumleft:. It is estimated that the neurons within the gut are responsible for up to 95% of the dopamine present in the body.
Better understanding your brain chemistry (dopamine & serotonin) would perhaps be of intrigue for you my friend..:thumleft:
