​IBS (Irritable Bowel Syndrome) Doctor Q&A

April marks IBS (irritable bowel syndrome) awareness month. Did you know IBS affects up to 9 per cent of Singaporeans? It belongs to a group of benign conditions known as functional gastrointestinal disorders (FGID).

Although the exact causes of IBS and FGID are unknown, they can be attributed to diet intolerance, stress, depression, abnormality in intestinal bacteria content and abnormal intestinal tract movement.

While IBS generally does not result in death, symptoms may be bothersome but can be brought under control with treatment.
