Inflammatory bowel disease (IBD) is a growing global health challenge, affecting over 7 million people worldwide. Once rare in Asia, IBD rates have increased sharply, with countries like South Korea, China and Japan experiencing rapid growth in cases. In fact, Hong Kong alone has seen a 30-fold increase in three decades, with annual costs expected to exceed HK$400 million (US$51.4 million).

IBD is driven by immune-related inflammation in the gut, causing symptoms such as abdominal pain, diarrhoea, bleeding and fatigue. In severe cases, it can lead to permanent bowel damage and the need for surgery.
