Rwy'n deall y gall yr effaith fod yn ddifrifol iawn ar gyfer y cleifion hynny sy'n dioddef problemau, ac fe fyddwn yn annog unrhyw glaf i ofyn am gyngor parhaus gan eu meddyg teulu neu arbenigwyr fel arfer. Ar ben hynny, os oes ganddynt unrhyw bryderon ynghylch eu gofal, dylid codi’r pryderon hynny drwy weithdrefnau Gweithio i Wella GIG Cymru. Gallant gael cymorth i wneud hynny drwy'r Cyngor Iechyd Cymuned perthnasol. Gellir gweld manylion y cysylltiadau hyn drwy'r dolenni canlynol:
I do appreciate that for those patients who suffer problems, the impact can be severe. and I would urge any patient to ensure they seek ongoing advice from their GP or specialists in the usual way. In addition, if they have any concerns regarding their care, they should raise these concerns through NHS Wales’ Putting Things Right  arrangements. They can be supported to do so through their local Community Health Council. Details of these contacts can be accessed via the following links:
