Wrth i'r GIG gyrraedd 75 oed, mae'r Gweinidog Iechyd, Eluned Morgan, wedi nodi sut y bydd angen diwygio'r GIG a sut y bydd angen i'r cyhoedd helpu i lunio'r diwygiadau hynny os yw'r GIG am ddathlu canmlwyddiant.
As the NHS turns 75, Health Minister Eluned Morgan has set out how the NHS will need to be reformed and how the public will need to help shape those reforms if the NHS is to celebrate a centenary.
