Irritable Bowel Syndrome (IBS) is a chronic gastrointestinal condition that affects millions of people in the UK, with no obvious cause.
While some symptoms may be experienced by those who do not have IBS, people diagnosed with irritable bowel syndrome will experience them more frequently and over a longer period of time.
IBS is a type of functional gastrointestinal (GI) disorder which can cause painful and embarrassing side effects.
