Gut / Bowel / Stomach

The gut, bowel and stomach are parts of the digestive system. They are responsible for breaking down food and drink, absorbing the useful nutrients and energy and getting rid of the waste. From simple problems such as indigestion, to more serious ones such as cancer, you can read all about the symptoms and check the treatments in our doctor-authored leaflets. If you have a gut-related question such as “What is appendicitis?” or “Have I got symptoms of threadworms?” our information may be able to help you find the answer. You can also learn about various tests and procedures such as screening for colorectal cancer, and why fibre is important in your diet.
