A ward has been closed at Llandudno Hospital as health bosses push forward £48m development plans.
A total of 20 beds have been closed across three wards, but hospital managers decided to "consolidate" them, closing one ward.
A spokesperson said patient care was not affected and the move would allow the redevelopment to get under way.
Plans include additional operating theatres for day surgery and a "modernised" outpatients department.
A specialist centre for women's health with breast services and a fertility clinic is also planned, but final approval is needed from the assembly government.
'More local services'
A spokesperson for Betsi Cadwaladr University Health Board said: "Over the last few months up to 20 beds across three wards in Llandudno have been closed.
"These beds are now going to be consolidated into one area, allowing best use of the beds available in the remaining two wards, ensuring safe care for the patients in Llandudno Hospital.
"Releasing this space will allow the redevelopment of the Llandudno Hospital site to get under way in line with the plans approved by the health board last month, leading to more local services being delivered in the hospital."
The spokesperson said this would start with the expansion of rheumatology services in Llandudno.
Discussions with staff affected have started to "make sure their skills are retained" and "used locally" amid speculation health workers could be redeployed off-site.
"No staff have been told they will be redeployed to Ysbyty Gwynedd [Bangor]," said the spokesperson.
