Gut troubles like gastric disorder in early life may alter the process the brain functions and increase the vulnerability of depression and anxiety in later stage of life. American researchers have noticed that gastric irritation in newborn rats seemed to enhance the expression of the stress hormone, corticotrophin-secreting factor CRF, and increase sensitivity to anxiety later in life.
Dr Pankaj Pasricha from Stanford University School of Medicine in California and his team recommended in a paper published in PLoS ONE that some human psychological illness may be the outcome, rather than the reason, of gastrointestinal troubles for instance irritable bowel disorder.
"Gastric irritation during the first few days of life may reset the brain into a permanently depressed state.The gut and the brain are hardwired together by the vagus nerve, which runs from the brain to the body's internal organs”Professor Pasricha, professor head of gastroenterology and hepatology.
He narrated that the gut has its own, almost separate nervous system and that interaction between gut and the normal brain is comprehensive and bi-directional, and changes in the gut are transmitted directly to the brain.
The US Food and Drug Administration (FDA) have approved electrical triggering of the vagus nerve as a new treatment for depression for those who do not respond to other treatments. The researchers believe their endeavors will assist to increase understanding in this type of treatment.
