Irritable bowel syndrome (IBS): The Role of Diet and a Dietitian

Have you ever wondered why you may be experiencing extra gas, bloating, or changes in bowel habits? These symptoms could be related to Irritable Bowel Syndrome (IBS), a common gastrointestinal disorder that affects a significant portion of the population. IBS is a functional disorder, meaning it impacts how your digestive system functions without causing structural damage. Gut health issues are a major concern but often can improve with changes in your diet. Many factors can increase your chance of experiencing IBS symptoms, these include stress, poor diet, lack of exercise and sleep. 

The Role of Diet in Managing IBS 

Diet plays a crucial role in managing IBS symptoms, because certain foods can trigger discomfort and exacerbate digestive issues. However, there is no one-size-fits-all approach, and what works for one person may not work for another. This is where the expertise of a dietitian comes in.

What can a dietitian do to help you with IBS?

Personalised Approach: IBS symptoms and triggers are unique to each individual. A dietitian can explore your triggers for these symptoms and help to create a personalised dietary plan that addresses your specific needs.

Guide You Through the Low FODMAP Diet: Provide education and practical tips to help guide you through a diet that can test for any FODMAP* intolerances by following the Low FODMAP* Diet. 

Evidence-Based Guidance: Dietitians rely on the latest research and evidence-based practices to guide their recommendations, ensuring that you receive scientifically backed advice.

Comprehensive Care: Managing IBS involves more than just dietary changes. A dietitian can provide holistic care by addressing lifestyle factors, stress management, and overall well-being.

Ongoing Support: IBS symptoms can change over time. A dietitian will monitor your progress and adjust your diet as needed, offering ongoing support.  

What is FODMAP Diet? 

A FODMAP diet works initially on lowering the foods that contain FODMAPS, these are: 

Fermentable 

Oligosaccharides 

Disaccharides 

Monosaccharides 

And  

Polyols  

These are naturally occurring types of sugars. Research has found that around 80% of people with IBS can improve their symptoms with this diet, in 3 steps:

1. Elimination: Restricting high-FODMAP foods to reduce symptoms  

2. Reintroduction: Gradually reintroducing foods to identify specific triggers  

3. Personalisation: Developing a long-term eating plan that minimises symptoms while ensuring nutritional balance.

IBS can significantly impact your daily life, but with the right guidance, its symptoms can be effectively managed. Working with a dietitian helps you to understand your gut physiology, and how your body reacts to the foods you eat. By identifying these foods, we can start to build a personal plan to help your gut feel comfortable again and regain control over your digestive health and improve your overall quality of life.
