What is IBS?
Irritable bowel syndrome (IBS), also known as irritable colon, is a very common gastrointestinal disorder that affects 1 in 7 people. It affects the digestive system, where the symptoms occur mainly in the large intestine. Food intolerances are often associated with IBS.
Causes of IBS
The exact cause of IBS is not known. There are, however, numerous factors that seem likely to play a role in its development. These include:
- Diet: Food is thought to be a prime culprit in the development of IBS. Food, of course, can have a major influence on the gut microbiome which plays a key role in digestive health. This is one reason our IBS nutritionist often recommend following a low FODMAP diet to manage IBS symptoms.
- Nervous system abnormalities Nerves within the digestive systems of some people may overreact when the gut is stretched because of gas or overeating. This can cause pain, diarrhoea or other annoying responses.
- Gastroenteritis is a type of infectious diarrhoea that affects the intestinal tract. IBS has been known to develop in people who have experienced severe cases of gastroenteritis. It is important to reiterate that it is not always possible to track down the root cause of IBS in every individual. However, our IBS dietitians are usually able to effectively relieve the symptoms nonetheless.
Common Symptoms of IBS:
Stomach pain or cramps
Stomach pain or cramps are usually worse after eating and can get worse as the day goes by.
Bowel Changes
This can be constipation, diarrhea or alternating between constipation and diarrhea, meaning erratic and unpredictable and bowel habits
Bloating
Abdominal bloating - the sensation of an inflated balloon in the abdomen, your tummy feel uncomfortably full and swollen
Excessive wind/gas/ fart
Excessive flatulence where passage of flatus/gas/wind is greater then usual.
Fatigue
IBS may cause fatigue
IBS Dietitian Consultation – Our 3‑Step Process
In‑Depth Assessment
Your IBS dietitian consultation begins with a comprehensive assessment of your symptoms, lifestyle, medical history and diet. This helps us understand your unique gut profile and identify possible triggers.
Personalised Nutrition Plan
Based on your assessment, your dietitian will create a tailored plan which may include low FODMAP guidance, microbiome-supporting strategies, symptom tracking, dietary adjustments and supplement recommendations where appropriate.
Ongoing Support & Review
IBS symptoms can fluctuate, which is why ongoing support is essential. Your dietitian will monitor your progress, help you reintroduce foods safely, adjust your plan and guide you through long-term symptom management.
Gut Microbiome & Weight Loss – Dietitian Support
Your gut microbiome plays a key role in appetite regulation, metabolism, energy balance and inflammation — all of which can influence weight. Our gut microbiome weight loss dietitian team helps you optimise digestive health in a way that supports sustainable weight management.
We focus on improving microbiome diversity through fibre-rich, plant-forward eating, personalised nutrition strategies, targeted probiotics when appropriate and balanced lifestyle changes. This approach helps improve digestive comfort while supporting healthy, long-term weight outcomes.
What is the best diet for IBS management/ relief?
There are many different dietary strategies that can help relieve IBS symptoms. Research at Monash University, King’s College, London and numerous other centres around the world has shown that a low FODMAP diet improves IBS symptoms in at least 75% of IBS sufferers. Therefore, a low FODMAP diet is the first treatment choice for people suffering from IBS.
FODMAP DIET
The FODMAP diet is considered one of the best and most effective IBS treatments.
What does FODMAP mean?
- Fermentable – gut bacteria ferment undigested carbohydrate to produce gases
- Oligosaccharides – Fructans & GOS – found in foods such as wheat, rye, onions, garlic and legumes/pulses.
- Disaccharides – Lactose – found in dairy products like milk, soft cheeses and yogurts.
- Monosaccharides – Fructose – found in honey, apples, high fructose corn syrups, etc.
- And
- Polyols – Sorbitol and Mannitol – Found in some fruit and vegetables and used as artificial sweeteners.
Put simply, FODMAPs are a collection of short-chain carbohydrates (sugars) that aren’t absorbed properly in the gut, which can trigger symptoms in people with IBS. FODMAPs are found naturally in many foods and food additives.

3-step process to manage your IBS symptoms and feel at your absolute best With an ibs nutritionist!
Trust the FODMAP nutritionists at Dietitian Fit to help you obtain relief from symptoms of your Irritable Bowel Syndrome. All treatments are grounded firmly in nutritional and dietary science and do not require the use of potentially problematic pharmaceuticals.
Step 1: Low FODMAP Diet
Week 1-2: Remove all high FODMAP food to get rid of 80-90% of the symptoms.
Step 2: FODMAP Reintroduction
Week 3-8: FODMAP rich foods are reintroduced foods back into your diet one by one (total of 6 food groups) to identify which FODMAP types trigger your IBS symptoms, and which do not.
Step 3: FODMAP Personalization
After identifying your high FODMAP trigger foods, foods that are well-tolerated are reintroduced back into your diet.
In most cases, you will be able to reintroduce many high FODMAP foods back into your diet, but you may not be able to eat them in the same quantity as before.
Your IBS dietitian may also recommend you specific probiotics to increase your gut health and improve tolerance to some foods.
