What is Irritable Bowel Syndrome?

Irritable Bowel Syndrome (or IBS) is a gastrointestinal disorder of the gut-brain interaction characterized by symptoms of recurrent abdominal pain associated with altered bowel habit (constipation, diarrhhoea or both) in the absence of organic disease.

While the exact cause of IBS remains unknown, it has been proposed that disturbances in the intestinal nerves that affect motility and perception of intestinal stretching may result in symptoms. Causes of these disturbances may depend on the interaction of several factors including genetics, psychosocial factors (e.g. anxiety, depression), and post-inflammatory changes after a gastrointestinal infection (e.g. gastroenteritis).

IBS Diagnosis

How is IBS diagnosed?

IBS is diagnosed by a doctor, after the exclusion of other conditions and cause of symptoms. 

Diagnosis of IBS is symptom-based using the Rome IV criteria.

ROME IV Criteria

Recurrent abdominal pain on average at least one day a week in the last three months associated with two or more of the following:

  • related to defecation

  • associated with a change in a frequency of stool

  • associated with a change in form (consistency) of stool.

Symptoms must have started at least six months ago.

How can a IBS Dietitian help you?

Diet plays a key role in the management of IBS. Some interventions that may be considered in the management of IBS can include: Change in dietary habits, modified fibre diet, reduction of gut irritants, consideration of prebiotics and probiotics, incorporation of digestive enzymes as well as application of Specialised Elimination Diet (Low FODMAP diet). 

FODMAP Diet Perth

Is the Low FODMAP Diet for you?

The low FODMAP diet is an evidence based dietary strategy to successfully manage IBS. FODMAP is an acronym for Fermentable Oligo-, Di, Mono-saccharides And Polyols. It is considered to be a second-line dietary strategy after assessment and management of dietary and lifestyle factors that may contribute to symptoms. 

The low FODMAP diet involves collective restriction of a group of short-chain carbohydrates that have been shown to  increase small intestinal water volume and be rapidly fermented in the large intestine, leading to increased gas (e.g. hydrogen) production and gastrointestinal symptoms (i.e. pain, bloating, distension, flatulence, nausea and altered bowel motility).

The low FODMAPs diet is a dietitian-taught program to ensure nutritional intake adequacy despite food restrictions. The long-term restriction of FODMAPs is not recommended. Structured reintroduction of  FODMAPs is recommended after two to six weeks to identify which FODMAPs you are sensitive to, your level of tolerance to each individual high FODMAP foods, and optimise food variety and self-management long term.
