Proposed changes to the way health services are delivered on Anglesey have been revealed by NHS managers.
There are three options for Ysbyty Penrhos Stanley
Anglesey Local Health Board (LHB) said the island's two community hospitals would remain open, but with three options for their future services.
Some in Holyhead, where Ysbyty Penrhos Stanley is based, said they hoped there would be proper consultation.
The LHB plans public meetings and said the review was responding to changing needs, including an ageing population.
In Llangefni, supporters want to see the community hospital retain all its present services.
The LHB said the number of people aged over 85 had grown "significantly".
"There are numerous environmental factors that are changing and we need to ensure we have a modern health service able to meet the public need in the future and it is for that reason that we have launched this consultation," said a spokesman.
Option 1 - Leaving the service unchanged
Option 2 - Develop community services and retain a mix of beds for care of the elderly and older people with memory problems at Penrhos Stanley, and care of the elderly beds at Ysbyty Cefni
Option 3 - Develop community services and change Ysbyty Penrhos Stanley into centre for care of the elderly and Ysbyty Cefni into care of older people with memory problems
"We have already worked extensively with health professionals, voluntary groups, councillors and politicians to draw up three options for change and we are now looking for public views and input into the process," he added.
Holyhead councillor Keith Thomas said: "I feel that some of the changes put forward as options for change by the health board have already been put into practice - things like moving elderly people with dementia.
'Further than necessary'
"I just hope that during the consultation period the health board will listen to the public and that any changes aren't just steam-rollered though".
In Llangefni, supporters of Cefni hospital said they were happy with the services provided at the hospital at the moment.
"This hospital is centrally positioned on the island and I wouldn't like to see elderly people in particular having to travel any further than necessary for treatment," said councillor Fflur Hughes.
The LHB is to hold roadshows at supermarkets and community facilities, as well as a series of public meetings.
