Cwblhawyd adolygiad manwl o wasanaethau IBD yng Nghymru yn 2020. Fe wnaeth yr adolygiad ganfod nifer o heriau, megis amrywiad mewn ymarfer rhwng gwasanaethau'r byrddau iechyd, pwysau ar y gweithlu, ac anhawster cael mynediad at dimau IBD a gwasanaethau cymorth. Roedd hyn yn unol â chanfyddiadau arolwg meincnodi IBD ledled y DU yn 2019.
A detailed review of IBD services in Wales was completed in 2020. It found a number of challenges, such as variation in practice between health board services, workforce pressures, and difficulty accessing IBD teams and support services. This was in line with the findings of the UK-wide IBD benchmarking survey in 2019.
