What does the digestive system do and how does it work?

The function of the digestive system is to turn food into essential nutrients for your body. A group of organs work together to do this. Understanding how the digestive system works could help you to spot potential problems early.

Here’s the typical process:

  • When your digestive system is in its normal rhythm, food and fluid pass regularly from the stomach into the small intestine.

  • Food is then broken down and nutrients are absorbed, along with most of the fluid.

  • The remaining waste and some water pass into the colon (large intestine), where more water is absorbed.

  • Finally, any waste is passed in the form of stools.

How do you get diarrhoea and what happens?

Diarrhoea can be a sign of digestive disruption. When your digestive system becomes irritated, the normally steady and regular movement of the gut can become overactive.

The result is that salts and fluid are moved through too quickly and less is absorbed by the body. The outcome? Loose or watery stools, otherwise known as diarrhoea .

Stomach bugs and food poisoning are common causes of diarrhoea. And it may take five to seven days for your diarrhoea to stop.
