Digestive diseases

What are digestive diseases?

A digestive disease, or disorder, involves something going wrong with one of the organs in the digestive system.

The digestive system is a tube made up of the mouth, oesophagus, stomach, small intestine and large intestine, which leads to the back passage. It also contains organs such as the liver, gallbladder, and pancreas.

Each part of this system has a different purpose, such as breaking down food, absorbing nutrients, or removing toxins or alcohol.
