What is the GI Tract and How Does It Work?

The GI tract stretches all the way from your esophagus to your stomach. This is also includes the small intestines, and large intestines. It also includes the colon, liver, and pancreas. This is in addition to the gallbladder, as well as bile duct.

Recent studies show that the digestive system (GI Tract) is important to the overall health of the entire body. Issues with any area of the GI system can upset weight management, energy, and mood which can then accelerate to more serious diseases.

How It Works:

Digestion begins during the moment you chew your food or take a sip of a drink. It is the movement of food through your digestive tract which then permits a process to begin. This will then allow your body to break down food. This includes the absorption of nutrients as well as the removal of waste products.
