The brain and digestive system link

Studies have been conducted and they have found a complex link between the digestive system and the brain. The link is quite sensitive to mood. Do you know that the stomach and intestines have more number of nerve cells than those present in the entire spinal cord and there are a number of nerves running from the brain to the digestive system? 95% of the serotonin present in the body is found in the digestive system and not in the brain. Serotonin is a hormone that regulates mood.

The process of digestion is controlled by the enteric nervous system that comprises of millions of nerves that happen to communicate with the central nervous system. When you are under stress, the body’s entire focus is on staying alive and this way it neglects digestion. The body shuts down the flow of blood to the digestive system, contractions of the digestive organs get affected and there is a decrease in the secretion of digestive enzymes.

Brain How digestion is affected by stress

The brain releases a number of hormones that wreak havoc on the digestive system. For instance, a hormone called corticotropin is released that suppresses appetite, this clears why some people can’t eat food when they are stressed out. The main function of the hormone is to instruct the adrenal gland to produce adrenaline and steroids that provide the strength to fight or flee from the stressors. In some people these steroids can make certain people feel extremely hungry, making them eat chips, chocolate and other junk food when they have stress.
