Inflammatory Bowel Disease (IBD) is a chronic condition that affects many people in Singapore and worldwide. However many Singaporeans are still unfamiliar with what it truly means to live with the condition. This guide provides a clear overview about what IBD is and its symptoms, causes, treatments, and costs – to help you understand this complex condition and seek timely medical care.

What Is IBD?
Inflammatory Bowel Disease, or IBD, refers to a group of chronic disorders that cause inflammation of the digestive tract. The two main types are:
- Crohn’s Disease – Can affect any part of the digestive tract from the mouth to the anus. Inflammation often extends deep into the layers of the bowel wall.
- Ulcerative Colitis – Affects only the large intestine (colon) and rectum, with inflammation limited to the innermost lining.
Both forms of this condition can cause recurring episodes of abdominal pain, diarrhoea, fatigue, and weight loss. Unlike temporary digestive discomfort, IBD is long-term and requires continuous medical management. It is an autoimmune condition, meaning the body’s immune system mistakenly attacks healthy tissues in the digestive tract, leading to inflammation and damage.
IBD should not be confused with Irritable Bowel Syndrome (IBS), which does not cause inflammation or intestinal damage. IBS is functional — it affects how the bowel works — while IBD is inflammatory and can lead to serious complications if untreated.
IBD Singapore Statistics
IBD was once considered rare in Asia, but this is no longer the case. In recent years, Singapore has seen a steady rise in IBD cases, mirroring trends in other developed countries. There are an estimated 3,000 patients with this condition in Singapore today, most commonly seen in teenagers and young adults aged 16 – 40 (Source: SGH). In addition, as much as 50% of Crohn’s disease patients and 30% of ulcerative colitis patients require at least one disease-related surgery in their lifetime.
The rise in cases may be linked to urban lifestyles, dietary changes, genetic predisposition, and environmental factors. Early recognition and diagnosis are essential to prevent long-term complications such as bowel obstruction or malnutrition.
Causes & Risk Factors
The exact cause of IBD remains unknown, but research suggests a combination of genetic, immune, and environmental factors.
1. Genetic Factors
People with a family history of IBD are at higher risk. Certain genes have been identified that may make individuals more susceptible to abnormal immune responses in the intestines.
2. Environmental Triggers
Diet, pollution, and the use of antibiotics may alter gut bacteria, triggering inflammation in susceptible individuals. Modern urban living — including processed food intake and low-fibre diets — may increase risk.
3. Lifestyle & Other Risk Factors
- Smoking: Increases risk of Crohn’s disease and worsens symptoms.
- Stress: Can aggravate flare-ups, though not a direct cause.
4. Age
Most people are diagnosed between 16 and 40 years old.
5. Ethnicity
IBD is more common among people of European and East Asian descent, though rising across all groups.
Symptoms Of IBD
Symptoms of IBD can range from mild to severe and often appear in “flare-ups” followed by periods of remission. Common symptoms include:
- Persistent diarrhoea, sometimes with blood or mucus
- Abdominal pain and cramping
- Fatigue and low energy levels
- Loss of appetite and unintended weight loss
- Urgent need to pass stools
- Anaemia due to blood loss
- In severe cases, complications such as bowel obstruction or perforation
Symptoms can vary depending on whether the patient has Crohn’s disease or ulcerative colitis. If you notice persistent digestive symptoms lasting more than a few weeks, it is important to see a gastroenterologist for evaluation.
Screening & Prevention
While there is no guaranteed way to prevent IBD, early detection and proactive management can make a significant difference.
Screening Methods:
Doctors may recommend the following tests to confirm a diagnosis:
- Colonoscopy or sigmoidoscopy – to examine the colon and collect tissue samples
- Blood tests – to check for inflammation or anaemia
- Stool tests – to detect infection or intestinal inflammation
- Imaging scans – such as CT or MRI for small intestine evaluation
Prevention Tips:
Although IBD cannot be fully prevented, these habits can reduce flare-ups and promote digestive health:
- Maintain a balanced, high-fibre diet (unless advised otherwise during flare-ups)
- Stay hydrated and limit processed foods
- Avoid smoking and excessive alcohol
- Manage stress through mindfulness, exercise, or counselling
- Attend regular check-ups to monitor symptoms
IBD Treatments
Treatment for IBD focuses on reducing inflammation, relieving symptoms, and preventing complications. The best approach varies depending on the severity and location of the disease.
1. Medication
- Aminosalicylates (5-ASAs): Help control mild inflammation
- Corticosteroids: Reduce inflammation during flare-ups
- Immunomodulators: Suppress immune system overactivity
- Biologic Therapies: Target specific immune pathways to achieve long-term remission
2. Dietary & Lifestyle Changes
A tailored diet plan can reduce discomfort. Some patients benefit from avoiding dairy, fried foods, or high-fat meals during flare-ups. Nutritionists can help create a balanced plan to maintain nutrient intake.
3. Surgery
In severe cases, surgery may be needed to remove damaged sections of the intestine or to manage complications like strictures or fistulas. Surgical techniques have improved significantly, allowing faster recovery and better quality of life.
4. Psychological Support
IBD can affect mental well-being. Counselling, support groups, and mental health care can help patients manage stress and emotional challenges associated with chronic illness.
Costs Of IBD Treatment
The cost of IBD treatment in Singapore varies based on the hospital, treatment type, and medication prescribed. On average:
- Consultation with a gastroenterologist: S$150–S$300 per session
- Colonoscopy: S$3,800–S$5,000
- Medication (5-ASAs, steroids, or biologics): S$200–S$3,000 per month, depending on severity and type of medication.
- Surgery (if required): S$15,000–S$30,000 depending on required procedure.
Subsidies are available at public hospitals under the MediSave and MediShield Life schemes. Some private insurance plans also cover IBD treatment and biologic therapies.
Early management can reduce overall treatment costs and prevent complications that may require surgery or hospitalisation.

Frequently Asked Questions (FAQs)
No. IBS (Irritable Bowel Syndrome) does not cause inflammation or damage to the intestines. IBD, on the other hand, is an autoimmune condition that causes chronic inflammation and can lead to serious complications.
Currently, there is no permanent cure for IBD. However, with medication, lifestyle adjustments, and regular medical care, many patients achieve long-term remission and lead normal, active lives.
Genetics play a role — having a family member with IBD increases your risk. However, not everyone with a genetic predisposition develops the disease.
Stress doesn’t directly cause IBD, but it can trigger or worsen symptoms. Managing stress is an important part of controlling flare-ups.
Yes. A balanced diet that avoids trigger foods (such as dairy, fried, or spicy foods) can reduce symptoms. A dietitian can help create an individualised nutrition plan.
