Doctor's Desk

Ulcerative Colitis 

is an inflammatory bowel disease that can affect any part of the lining of the large bowel, characterised by periods of flares and remissions.

The cause of Ulcerative Colitis (UC) is still unknown; however the environment, genes and the gut bacteria are thought to be involved.


Diagnosis for UC may include colonoscopy, endoscopy, imaging studies such as barium x-rays and abdominal CT, stool cultures, and sigmoidoscopy.

Dietary management of UC

Diet plays a key role in the management of UC. Some interventions that may be considered in the management can include:

  • Change in dietary intake to meet nutrient requirements (energy, protein)

  • Prevention and management of mineral and vitamin deficiency & supplementation

  • Modified fibre diet (active or in remission)

  • Probiotic supplementation (inducing remission and maintenance of remission) 

  • Prebiotic supplement (active or in remission)

  • Elimination Diet (Low FODMAP diet) in managing functional symptoms (in remission)

Healthy Food

The Low FODMAP Diet 

The low FODMAP diet is an evidence based dietary strategy to successfully manage of functional symptoms when your UC is in remission. 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.
