Irritable bowel syndrome (IBS) is the name for a group of symptoms that occur in your gastrointestinal system. These symptoms are collectively named a functional gut disorder as there is no underlying disease.

However, despite the absence of disease, the function of the gut can still be disturbed and cause undesirable side-effects.

A diagnosis of IBS will often be made by a General Practitioner (GP) or specialist such as a Gastroenterologist. The diagnosis is generally reached once a comprehensive medical history has been taken, including the type and duration of symptoms present. Sometimes a scope may be required to have a closer look inside your gut.

There is no one cause of IBS. However, it is known that diet, stress, genetics, medications and viruses all play a role. Certain antibiotics can cause an imbalance of bacteria, and in some cases, bacteria can migrate to the small intestine.

Evidence is constantly emerging on the link between our gut and brain. This is known as the gut-brain-axis. It is also known that some individuals simply are more sensitive than others. The enteric nervous system runs the entire length of the digestive system, so if one is out, the other will be triggered.

Symptoms of IBS

Reported symptoms can include:

  • bloating (distention)
  • trapped wind
  • excess gas
  • abdominal pain, cramping
  • nausea
  • reflux
  • constipation
  • diarrhoea
  • combination of both constipation and diarrhoea
  • fatigue
  • reduced quality of life

Classification of IBS

IBS is classified using the ‘Rome 111’ classification, which determines that someone can be diagnosed with IBS if they have suffered symptoms of a functional gut disorder for at least six months. They must also have experienced abdominal pain or distension associated with altered bowel habits. Time limits are used to differentiate between a one off gut incident such as a gastrointestinal bug or an ongoing issue.
