Understanding Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome is a functional gastrointestinal disorder characterised by recurrent abdominal pain associated with changes in bowel habits. Unlike inflammatory bowel disease, IBS does not cause visible damage to the bowel or increase cancer risk.
Irritable Bowel Syndrome (IBS) arises from intricate interactions between the gut and brain (the 'gut-brain axis'), encompassing altered gut motility, visceral hypersensitivity, gut microbiome changes, and psychological factors, necessitating comprehensive IBS treatment approaches. Understanding these mechanisms guides effective treatment.
Common Symptoms
IBS Subtypes
IBS-D (Diarrhoea-predominant)
Characterised by frequent loose stools, urgency, and often morning diarrhoea. May be associated with anxiety.
IBS-C (Constipation-predominant)
Infrequent, hard stools with straining. Often associated with bloating and abdominal discomfort.
IBS-M (Mixed)
Alternating between diarrhoea and constipation. Symptoms may vary day to day or week to week.
IBS-U (Unclassified)
Meets IBS criteria but stool patterns don't fit clearly into other subtypes.
Common Triggers
Identifying and managing triggers is key to controlling IBS symptoms. Triggers vary between individuals.
Dietary
- FODMAPs (fermentable carbohydrates)
- Fatty or fried foods
- Caffeine and alcohol
- Artificial sweeteners
- Large meals
Lifestyle
- Psychological stress
- Anxiety and depression
- Poor sleep
- Lack of exercise
- Irregular eating patterns
Other
- Hormonal changes (menstruation)
- Post-infectious (gastroenteritis)
- Antibiotic use
- Food intolerances
- Small intestinal bacterial overgrowth
Alarm Symptoms
These symptoms are NOT typical of IBS and require investigation to exclude other conditions.
Rectal Bleeding
Blood in stool is not a feature of IBS and requires investigation.
Unexplained Weight Loss
Significant unintentional weight loss needs further evaluation.
Onset After Age 45
New symptoms in older adults warrant colonoscopy.
Nocturnal Symptoms
Symptoms waking you from sleep suggest organic disease.
Many digestive symptoms such as abdominal discomfort, bloating, diarrhoea, constipation, and changes in bowel habits are commonly attributed to Irritable Bowel Syndrome. However, some of these symptoms can also occur in Inflammatory Bowel Disease, a group of conditions that cause ongoing inflammation within the digestive tract.
Although IBS and IBD may share certain symptoms, they are fundamentally different conditions. IBS is considered a functional bowel disorder, meaning the bowel appears normal but does not function normally. In contrast, IBD involves actual inflammation and damage to the lining of the digestive tract and may lead to more serious complications if left untreated.
Understanding the differences between IBS and IBD is important, as the investigations, treatment approaches, and long-term implications can vary significantly.
Diagnosis
IBS is diagnosed based on symptom criteria (Rome IV) after excluding other conditions. Testing may be needed to rule out alternative diagnoses.
When Colonoscopy is Needed
Colonoscopy may be recommended to exclude inflammatory bowel disease, microscopic colitis, or colorectal cancer.
- Presence of alarm symptoms
- Age over 50 without prior screening
- Family history of colorectal cancer or IBD
- Symptoms not responding to treatment
Other Tests
Blood Tests
Full blood count, inflammatory markers, coeliac serology, thyroid function.
Stool Tests
Calprotectin (to exclude IBD), stool cultures, ova and parasites.
Breath Tests
Hydrogen breath tests for lactose intolerance or SIBO (small intestinal bacterial overgrowth).
Food Intolerance Testing
Structured elimination diets may identify specific triggers.

| Feature | Irritable Bowel Syndrome | Inflammatory Bowel Disease |
|---|---|---|
| What is it? | A functional bowel disorder affecting how the digestive system works | A chronic inflammatory condition of the digestive tract |
| Examples | IBS with diarrhoea, constipation, or mixed bowel habits | Crohn's disease and ulcerative colitis |
| Common symptoms | Bloating, abdominal pain, diarrhoea, constipation, excess gas | Abdominal pain, diarrhoea, urgency, rectal bleeding, weight loss |
| Blood in stool | Uncommon | Common |
| Weight loss | Usually absent | More common |
| Fever | No | Can occur during active inflammation |
| Inflammation in the bowel | No visible inflammation | Yes |
| Damage to the intestine | No | Can occur over time |
| Symptoms during sleep | Uncommon | May occur |
| Cause | Related to gut sensitivity, bowel movement changes, stress, and diet | Immune-related inflammation of the digestive tract |
| Is it serious? | Not dangerous, but can affect quality of life | Can lead to complications if untreated |
| Tests commonly performed | Usually diagnosed based on symptoms and simple tests | May require blood tests, stool tests, colonoscopy, and imaging |
| Treatment | Diet, lifestyle changes, stress management, symptom control | Anti-inflammatory medication, immune therapy, and sometimes surgery |
| Cancer risk | Does not increase bowel cancer risk | Long-standing disease may increase bowel cancer risk |
| When to seek specialist review | Persistent or troublesome symptoms | Any ongoing diarrhoea, bleeding, weight loss, or worsening symptoms |
IBS Treatment Approach
Effective IBS management in Singapore is highly individualized, integrating dietary changes, lifestyle modifications, and targeted medications tailored to predominant symptoms, under the guidance of an experienced IBS specialist doctor.
Dietary Management
- Low FODMAP diet (guided by dietitian)
- Identify and avoid personal triggers
- Regular meal patterns
- Adequate fibre intake (adjusted to tolerance)
- Limit caffeine and alcohol
- Probiotics (strain-specific)
Medications
For Pain/Spasm
Antispasmodics (mebeverine, hyoscine), peppermint oil capsules.
For IBS-D
Loperamide, bile acid binders, rifaximin (for bloating/SIBO).
For IBS-C
Osmotic laxatives, linaclotide, prucalopride.
Neuromodulators
Low-dose tricyclic antidepressants or SSRIs for pain modulation and gut-brain axis.
Psychological Therapies
CBT, gut-directed hypnotherapy, mindfulness - evidence-based for IBS.
Management of Your IBS
Living with IBS doesn't have to mean constant discomfort. It is crucial to consult an IBS specialist for accurate diagnosis and tailored treatment plans to effectively manage your symptoms.
Managing IBS Flare-Ups
Living with Irritable Bowel Syndrome can be frustrating, particularly during periods when symptoms suddenly worsen or “flare.” Common symptoms during a flare-up may include abdominal discomfort, bloating, diarrhoea, constipation, excess gas, or an urgent need to open the bowels.
Although IBS does not cause permanent damage to the digestive tract, flare-ups can significantly affect daily life and quality of life. Fortunately, many people are able to improve their symptoms with a combination of dietary adjustments, lifestyle measures, and targeted treatment.
Common triggers for IBS flare-ups
IBS symptoms can vary from person to person, but common triggers include:
- Regular exercise
- Adequate sleep
- Relaxation techniques or mindfulness
- Stress management strategies
- Avoiding excessive late nights and irregular routines
Medications
Depending on symptoms, medications may help:
- Antispasmodics for cramping
- Anti-diarrhoeal medication for diarrhoea
- Gentle laxatives for constipation
- Probiotics in selected patients
Treatment is usually tailored to the individual’s symptoms and pattern of IBS.
When to seek medical review
You should seek medical attention if:
- Symptoms are persistent or worsening
- You develop blood in the stool
- There is unexplained weight loss
- Symptoms wake you from sleep
- You develop fever or severe pain
- Symptoms begin later in life or change significantly
A gastroenterologist can help confirm the diagnosis, exclude other digestive conditions, and provide a personalised treatment plan to help improve symptom control and quality of life.
