EPSOM Hospital stands to lose its A&E and maternity units if recommendations published on Friday are followed.
The Better Standards Better Value (BSBV) review posted its draft preconsultation business case on its website, in which it recommended a "preferred option" that would see Epsom becoming an "elective care centre", losing both key services.
Further "alternative" and "least preferred" options would also lead to the hospital losing its A&E and maternity wards. All three options recommend that Kingston Hospital and St George's Hospital in Tooting remain as major acute hospitals.
Mole Valley MP Sir Paul Beresford said: "We are very upset about it. I personally am very upset.
"A group of us, led by [Epsom and Ewell MP] Chris Grayling and myself, are trying to see what we can do to prevent what they have put into their proposals, and see if we can bring a change.
"We want people, especially in the north of Mole Valley, to look very carefully at the proposals and use the consultation period."
He added: "If you are a pregnant lady about to give birth and living in Bookham, and the ambulance arrives and they have to rush you to St George's hospital in peak traffic hours – when it is in a peak traffic zone as it is – until they have got paramedics doing Caesareans in the ambulance, that is two lives in danger."
The draft will now be considered by the seven new local clinical commissioning groups (CCGs) associated with the hospitals in question during May.
The draft business case requires the unanimous support of CCGs in order for BSBV to put its proposals forward for public consultation.
A meeting of the Surrey Downs commissioning group's governing board will be held in public on May 17 at Epsom Downs Racecourse from 1.30 to 5pm, at which residents can voice their concerns.
Adrian Bartels, of Gatesden Road, Fetcham, told the Advertiser: "Travelling to St George's in Tooting involves terrible traffic at any time but in particular in the morning and evening rush hour.
"It's absolutely ridiculous. Anything that can be done to inspire common sense to prevail against the lunacy should be encouraged."
Matthew Hopkins, chief executive of the Epsom and St Helier NHS, Trust said: "Whilst I recognise there is a need to change and improve healthcare services in our region, on behalf of our patients, staff, volunteers and local residents, I am disappointed with this news and recognise that it will be very unsettling for many people around us.
"However, it is extremely important to note that these are only recommendations and that no decisions have been made at this stage.
"For instance, the recommendations still need to be agreed by the seven clinical commissioning groups. They will also be subject to a 14 week public consultation.
"In addition, should the proposals be agreed, we would not expect to see any change to services until 2017 or 2018 at the earliest."
