5. Buildup Of Bacteria
Source: https://www.health.harvard.edu
In order for the body to get the nutrients it needs, the body must first digest whatever food is taken into the system. Whatever goes into the body needs to be digested in one way or another, and this is how the good nutrients go to the bloodstream and the bad nutrients go to the colon. But when there are issues with this process, a buildup of bacteria can occur in the digestive tract, as well as in the intestines. When this happens, there is normally a buildup of gas as well, sometimes even causing some stomach pain and diarrhea.
