Definition
Irritable bowel syndrome is a chronic condition of the gut that results in a variety of symptoms including episodes of abdominal pain, cramps, bloating and altered bowel habit (constipation, diarrhoea or a combination of the two).
Prevalence
Because the definition of IBS varies it is difficult to say how common it is but a recent study (1)found that it affects about 1 in 10 people worldwide and in the UK the prevalence is reported as 10-20% by NICE (2)(National Institue for Health and Care Excellence)
Cause
It is conventionally referred to as a "functional" condition which means there is no single, specific, disease process responsible but rather it is an imbalance of the function of the gut. Having said this there are a number of factors which contribute to the development of IBS type symptoms and with more specific testing we are finding that there may in fact be a cause identified in many previously "ideopathic" cases.
There is a very strong link between the brain and the gut (known as the "Brain-Gut Axis") so stress is often a contributary factor. Many people find that their symptoms may be worsened by certain foods and there is a degree of food intolerance present. Another distinct cause can be an imbalance of the gut bacteria, termed "dysbiosis", or an overgrowth of bacteria in the small bowel, termed "SIBO". Detailed analysis can also show that there is a degree of inflammation within the bowel and/or a breakdown of the usual barrier function of the gut, termed "leaky gut".
Symptoms and Signs
The symptoms of IBS include abdominal pain (which is often cramping in nature and may be releived by passing stools), bloating, diarrhoea, constipation, passing excesive wind, nausea, dyspepsia, urinary symptoms, tiredness and "brain fog". Symptoms such as rectal bleeding, a persistent change to loose stools in those over the age of 50 years or unexpected weight loss may be a sign of a more serious underlying condition and should be promptly assessed.
Investigations
If you have symptoms of IBS it is important to see your GP who may arrange some tests (including blood +/- stool tests) however NHS testing is quite limited. If there are any concerns about a more significant underlying condition then endoscopy (camera) tests may be arranged. If conventional tests have not identified a cause for the IBS type symptoms then it may be helful to have further testing with a more comprehensive stool analysis or other tests as recommended by your health practitioner.
How is IBS managed?
Managment of IBS is aimed at reducing symptoms and improving quality of life. It may involve medications prescribed by your doctor (e.g. antispasmodics, laxatives or tricyclic antidepressants e.g. amitriptyline). You may be advised to cut out certain foods which exacerbate your symptoms or to avoid high FODMAP foods for a time. If there is an imbalance of gut bacteria then dietary approaches along with herbal treatments and probiotics can help to restore the balance.
