What is your digestive system?

The digestive system is made up of your 5 to 6 metre-long gastrointestinal (GI) tract, liver, pancreas and gallbladder. The organs of your digestive system work together to digest your food, turning it into nutrients and energy.

A digestive condition covers any health problem in our digestive tract, and symptoms usually involve stomach pain, constipation, diarrhoea, heartburn or bloating.
