Irritable Bowel Syndrome (IBS) is a common yet complex gastrointestinal condition that affects approximately 11% of the global population. Often misunderstood and frequently misdiagnosed, IBS can have a significant impact on an individual’s quality of life. At NXTLVL Health, we aim to bring clarity to this often frustrating condition and provide personalised, holistic support to those seeking relief.
What is IBS?
IBS is classified as a functional gastrointestinal disorder, which means there’s no detectable structural abnormality or pathology identifiable through standard medical testing. Instead, IBS is defined by how the gut functions. It’s characterised by chronic abdominal pain or discomfort and changes in bowel habits, such as constipation, diarrhoea or both.
The diagnosis is typically made using the Rome IV Criteria, which assess symptoms such as:
• Abdominal pain occurring at least once per week for the last three months
• Pain related to defecation
• Changes in the frequency or form of stools
Types of IBS
IBS is classified into subtypes based on stool consistency, often using the Bristol Stool Chart as a reference:
• IBS-C: Constipation-predominant
• IBS-D: Diarrhoea-predominant
• IBS-M: Mixed type (alternating constipation and diarrhoea)
• IBS-U: Unsubtyped
Each subtype presents unique challenges and may require different therapeutic approaches.
Common Symptoms
While no two IBS cases are the same, some of the most common symptoms include:
• Abdominal cramping or bloating
• Urgency or incomplete evacuation
• Excessive gas or flatulence
• Nausea and fatigue
• Mucus in the stool
It’s important to note that blood in the stool is not a symptom of IBS and warrants immediate referral to a GP for further investigation.
What Causes IBS?
IBS is multifactorial, and its underlying causes often vary between individuals. Current research suggests several contributing factors:
1. Gut–Brain Axis Dysregulation
The gut and brain are intricately connected through the parasympathetic, sympathetic, and enteric nervous systems. Stress or imbalances in this communication network can disrupt digestion and increase gut sensitivity — a common feature in IBS.
2. Altered Gut Motility and Serotonin Signalling
Changes in the way the gut muscles contract, along with abnormal serotonin levels (a key neurotransmitter involved in digestion), may play a role in IBS symptoms.
3. Post-Infectious IBS
Some individuals develop IBS following a bout of gastroenteritis or food poisoning, indicating a potential link to inflammation or microbial imbalance.
4. Dysbiosis and Food Sensitivities
An imbalance in the gut microbiota (dysbiosis) or undiagnosed food intolerances (e.g., FODMAP sensitivity, lactose intolerance) can significantly contribute to IBS symptoms.
Personalised Support at NXTLVL Health
At NXTLVL Health, we recognise that IBS is not a one-size-fits-all condition. Our naturopathic approach focuses on uncovering the root causes through comprehensive assessments, including:
• Functional pathology testing
• Gut microbiome analysis
• Food intolerance screening
• Nervous system and stress profiling
From there, we design customised treatment plans that may include dietary modifications (such as a low-FODMAP or gut-healing protocol), targeted herbal medicine, stress support, and lifestyle strategies to restore balance to the digestive system.
