Mae'r GIG yng Nghymru wedi gweld cynnydd yn nifer y cleifion hŷn ag anghenion cymhleth a chyflyrau cronig sydd angen cael eu trin mewn ysbyty. Mae hyn yn hynod o heriol i Gymru, sydd â'r gyfran uchaf o bobl dros 85 oed yn y DU.
The NHS in Wales has seen a rise in the number of elderly patients who have complex needs and chronic conditions who need to be treated at and admitted to hospital. This is particularly challenging for Wales, which has the highest proportion of people over 85 in the UK.
