The NHS in England is planning "previously unthinkable" cuts to try to balance the books, health bosses say.
Services including diabetes care for young people, rehab centres and talking therapies are in the firing line, according to NHS Providers, which represents health managers.
Staff, including doctors and nurses, also face the axe - and some NHS trusts are stopping overtime for doctors, putting the drive to cut the hospital waiting lists at risk.
NHS Providers said some of the savings were "eye-watering", but the Department of Health and Social Care said NHS services should focus on cutting bureaucracy and driving up productivity.
