Mae Pennaeth GIG Cymru, Judith Paget, hefyd wedi annog pawb i helpu i leihau'r baich ar y GIG drwy ystyried opsiynau eraill yn lle mynd i'r ysbyty, oni bai bod arnynt angen gofal brys.
The head of NHS Wales, Judith Paget, has also urged everyone to help reduce the burden on the NHS by considering other options to attending hospital, unless they need urgent care.
