Bu cydweithrediad parhaus ac agos â Crohn's & Colitis UK. Lansiodd y sefydliad ymgyrch Diagnosis Cynharach ar gyfer Anhwylderau'r Perfedd Isaf yng Nghymru yr hydref diwethaf. Mae wedi’i thargedu at oedolion ifanc ac mae’n annog pobl â dolur rhydd, poen neu waedu i gael help yn gyflym. Fe'i cefnogir gan lwybr clinigol y cytunwyd arno ar gyfer ymchwilio i glefydau'r perfedd isaf (IBD, clefyd seliag, syndrom coluddyn llidus, canser y colon a llawer o anhwylderau eraill).
There has also been ongoing and close cooperation with Crohn’s and Colitis UK. The organisation launched an Earlier Diagnosis for Lower Gut Disorders campaign in Wales last autumn. It is targeted at young adults and urges people with diarrhoea, pain or bleeding to get help rapidly. It is supported by an agreed clinical pathway for the investigation of lower gut diseases (IBD, coeliac disease, irritable bowel syndrome, colonic cancer, and many other disorders).
