All these organs constitute the digestive system, whose primary mission is to progress the food that we eat. Gastroenterologists have a thorough understanding of how food moves through the digestive tract (called motility) and the physical and chemical break down of food (digestion), including the absorption of nutrients and the removal of waste products. Gastroenterologists also focus on the digestive function of the liver.
The specialist in digestion also deals with the prevention and early detection of any pathology, especially in the case of colorectal cancer.
A digestive disease is any health problem that occurs in the digestive system. Some problems include lactose intolerance, irritable bowel syndrome, cancer etc.
