There are many different causes for hair loss through out life, such as post childbirth or through menopause for women and most men will lose some hair by the time they reach adulthood. But while some hair loss is considered normal, excessive prolonged loss is not.

You have most likely heard of the Gut brain Axis, referring to the bidirectional communication between the central nervous system (brain) and the enteric nervous system (gut), linking emotional and cognitive centres of the brain with peripheral intestinal function. But do you know much about the Vagus nerve that’s responsible for connecting them?

The vagus nerve aka the “wandering nerve” is a multi branched nerve that extends from the cerebellum in the brain down to the lowest viscera of the abdomen, reaching out to the heart and other organs on the way down. It is this nerve that is responsible for the communication between the gut and the brain.
