Your Digestive system is made up of the gastrointestinal (GI) tract and your liver, pancreas, and gallbladder. The GI tract is a series of hollow organs that are connected to each other from your mouth to your anus. The organs that make up your GI tract, in the order that they are connected, include your mouth, esophagus, stomach, small intestine, large intestine, and anus.
This system is responsible for taking food and converting it into the energy your body needs to function. How effectively it is able to do its job can be determined by many factors including the quality of the food you eat, how much stress you live with, and how well you sleep.
In functional health care, it is believed that the root cause of many symptoms begins in the GI system.
