Diagnosing flatulence

NHS Choices Medical Reference

NHS Choices Logo

Flatulence does not usually require a medical diagnosis unless you are also experiencing additional symptoms, such as persistent abdominal pain or blood in your stools, which may suggest that you have an underlying digestive condition.

In these circumstances, a blood test can be used to check for the presence of infection and to determine whether you have a condition that is linked to a food intolerance, such as coeliac disease or lactose intolerance.

Your GP may also ask you detailed questions about your symptoms and your bowel movements, such as whether you have to strain to pass a stool or if you experience abdominal pain after eating. This sort of information can be useful in confirming a diagnosis of irritable bowel syndrome (IBS).

If your additional symptoms are particularly severe, your GP may refer you for an endoscopy. An endoscopy is a procedure where a healthcare professional examines the inside of your stomach using a device called an endoscope. An endoscope is a thin, long flexible tube that has a light and a video camera at one end of it.

Blood supplies oxygen to the body and removes carbon dioxide. It is pumped around the body by the heart.
Constipation is when you pass stools less often than usual, or when you are having difficulty going to the toilet because your stools are hard and small.
Pain is an unpleasant physical or emotional feeling that your body produces as a warning sign that it has been damaged.
Stool (also known as faeces) is the solid waste matter that is passed from the body as a bowel movement.
