The digestive system spans from the mouth, down to the anus. Apart from the mouth and throat (which is reserved for dentists and ENT doctors respectively), gastroenterologists are the go-to doctors when it comes to the digestive system.

If you were wondering where the word ‘gastroenterologist’ came from, it’s actually derived from the Greek words ‘gastēr’ which means ‘stomach’, ‘enteron’ which means ‘intestines’ and ‘logia’ which means ‘reason’ or study’.

So, gastroenterology is the study of the gastrointestinal tract or the digestive system. In the past, gastroenterologists used to be called ‘gastrologists’ in some places. Nowadays, some people refer to them as 'gastrointestinal doctors', ‘gi doctors’ or ‘stomach doctors’

They are trained to understand the structure, function, passage of food, digestive process, removal of waste products and diseases that affect structures like the esophagus, stomach, liver, gallbladder, pancreas, small intestine, large intestine, rectum and anus.

In this case, gastroenterologists spend about 6-7 years after completing medical school to become certified and accepted into the colleges of gastroenterology.
