Irritable Bowel Syndrome or Inflammatory Bowel Disease: How to tell the difference?
Published on 1 November 2021
Chronic tummy troubles? Learn whether symptoms point to a chronic stomach condition such as Irritable Bowel Syndrome (IBS) or to a more serious one known as Inflammatory Bowel Disease (IBD).
All of us suffer from the occasional change in bowel habits. Most often, these are caused by diet imbalances, lack of exercise, hormones or mild illness.
However, if bowel problems are chronic – lasting beyond a week or two – and if they are accompanied by severe pain and bloody stools, it may warrant seeking medical advice.
Getting to the gut of the issue
Two common reasons for chronic stomach issues are Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD).
These two stomach complaints share some similar symptoms but are actually different problems with different treatments and outcomes.
Dr Jessica Hay Tang, Family Physician, Clementi Polyclinic, National University Polyclinics (NUP) shared:
IBS is a functional gastrointestinal disorder that is chronic. Symptoms vary in severity and duration from person to person. IBS does not cause changes in bowel tissue or increase the risk of colorectal cancer.
IBD is an umbrella term for inflammatory gastrointestinal diseases that cause chronic inflammation of the digestive tract. These include ulcerative colitis and Crohn’s disease. IBD can increase the risk of colon cancer due to the ongoing active inflammation.
According to Dr Phua Yiyong, Family Physician, Choa Chu Kang Polyclinic, NUP, IBS can affect people of all ages. “Population studies reveal a preponderance towards women and those 40 years of age and younger,” he explained. Other risk factors include a family history and co-existing morbidities of depression and anxiety. In Singapore, about 20% of people suffer from IBS.
The incidence of IBD is not as high, but the disease is reportedly on the rise, and is most common in those aged between 20 to 40 – and in rare cases, children too.
Both IBS and IBD can seriously impact quality of life. In the case of IBD, it can be a serious problem and can increase the risk of cancer. This underscores the importance of consulting with a doctor so that the problem can be diagnosed and managed.

|IBS can be managed through education about the condition, its triggers, lifestyle changes and self-care techniques, which can reduce the severity of symptoms and improve the quality of life.|
Treatment for IBD depends on the causes of the inflammation as well as its severity.
