Dr Eric Wee, Senior Consultant Gastroenterologist at Nobel Gastroenterology Centre provides valuable insights into distinguishing between food poisoning, irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD). He explains that while these conditions share similar symptoms like abdominal pain and diarrhoea, IBD is more serious and often involves mucus and blood in stools, along with a longer, more chronic history compared to acute gastroenteritis.
