Ulcerative Colitis (UC) is a chronic inflammatory condition of the large intestine (colon) and rectum. It is one of the two main types of Inflammatory Bowel Disease (IBD), the other being Crohn’s Disease. In Singapore, awareness of IBD is steadily growing, as more patients present with persistent digestive symptoms that affect their quality of life. Understanding the condition is, and recognising its symptoms early can make a significant difference in effective management and long-term health outcomes.

What Is Ulcerative Colitis?
Ulcerative Colitis is a type of IBD that causes inflammation and ulceration of the inner lining of the colon. Unlike Crohn’s Disease, which can affect any part of the digestive tract, Ulcerative Colitis is limited to the colon and rectum. The inflammation leads to tiny open sores (ulcers) on the intestinal wall, which can cause pain, diarrhoea, and bleeding.
In Singapore, the exact number of people living with the condition is not well established, but gastroenterologists report a rising trend in both UC and Crohn’s Disease cases — reflecting patterns seen across Asia. Lifestyle changes, diet, and increased awareness may contribute to this apparent rise.
Causes And Risk Factors Of Ulcerative Colitis
The exact cause of Ulcerative Colitis remains unknown, but it is believed to result from an overactive immune response. In people with UC, the body’s immune system mistakenly attacks healthy cells in the colon, leading to chronic inflammation.
Several factors are thought to increase the risk of developing Ulcerative Colitis:
- Genetic Predisposition – Having a family member with IBD increases your risk.
- Immune System Dysfunction – An abnormal immune reaction may be triggered by environmental or bacterial factors.
- Environmental Triggers – Diet, stress, pollution, and even gut microbiota imbalances can play a role.
- Age – UC can develop at any age but is most often diagnosed between 15 and 40 years old.
- Ethnicity – People of certain ethnic backgrounds, including those of Asian descent, are increasingly affected.
While diet alone does not cause Ulcerative Colitis, certain foods may trigger flare-ups in those who already have the condition.
Common Symptoms Of Ulcerative Colitis
The symptoms of Ulcerative Colitis can range from mild to severe and may come and go in cycles, with periods of remission and flare-ups. Common symptoms include:
- Chronic Diarrhoea, often mixed with blood or mucus
- Abdominal Pain And Cramping, especially before bowel movements
- Urgent Need To Use The Toilet
- Rectal Bleeding or passage of blood-stained stool
- Fatigue And Weakness, due to loss of nutrients or anaemia
- Unintentional Weight Loss
- Fever During Active Inflammation
If these symptoms persist for more than a few weeks, it is important to consult a gastroenterologist. In Singapore, early referral to a specialist can help manage the condition before it leads to complications such as colon perforation, toxic megacolon, or increased colorectal cancer risk.
How Ulcerative Colitis Is Diagnosed
Diagnosing Ulcerative Colitis involves a combination of medical history, physical examination, and diagnostic tests. Common investigations include:
- Colonoscopy – The gold standard for diagnosis. It allows doctors to view the colon lining and take biopsies.
- Stool Tests – To rule out infections that mimic UC symptoms.
- Blood Tests – To check for inflammation markers or anaemia.
- Imaging Tests – Such as CT or MRI scans to assess disease extent and complications.
In Singapore, colonoscopy is widely available in both public and private hospitals, and it remains a key step in confirming the diagnosis and guiding treatment decisions. Find out how to prepare for a colonoscopy.
Treatment Options For Ulcerative Colitis In Singapore
While there is currently no known cure, treatment focuses on controlling inflammation, reducing symptoms, and maintaining remission. Management is typically personalised, depending on disease severity and the patient’s lifestyle.
1. Medication
- Aminosalicylates (5-ASA): Reduce inflammation in the colon.
- Corticosteroids: Used for short-term control during flare-ups.
- Immunosuppressants: Help prevent the immune system from overreacting.
- Biologic Therapies: Target specific molecules in the inflammatory process and are useful for moderate to severe cases.
2. Diet And Lifestyle Adjustments
Although no specific diet cures UC, some people find symptom relief through dietary changes, such as:
- Avoiding high-fat or spicy foods during flare-ups
- Eating smaller, more frequent meals
- Staying hydrated
- Managing stress through exercise, mindfulness, or therapy
3. Surgery
For patients who do not respond to medical therapy or develop severe complications, surgery may be necessary. This can involve removing the affected portion of the colon (colectomy). Advances in surgical techniques in Singapore, such as laparoscopic and robotic surgery, have improved recovery times and long-term outcomes.

Contact MedicalTravel.asiaFrequently Asked Questions (FAQs)
1. Is Ulcerative Colitis The Same As Irritable Bowel Syndrome (IBS)?
No. Ulcerative Colitis is an inflammatory disease that can cause ulcers and bleeding, while IBS is a functional disorder that affects bowel movement without inflammation.
2. Can Ulcerative Colitis Lead To Cancer?
Yes, long-standing UC may increase the risk of colon cancer. Regular colonoscopy screenings are important for early detection and prevention.
3. Is Ulcerative Colitis Curable?
There is no permanent cure yet, but effective treatments can help achieve remission and significantly reduce symptoms.
