One in three adults with severe M.E. has no access to local specialist services according to researchers at the University of Southampton.
They say a third of the units dedicated to patients with Chronic Fatigue Syndrome nationwide, aren't providing the care that's recommended for housebound patients, primarily due to a lack of funding.
It's estimated around 250,000 people in the UK have the condition.
Clare McDermott who led the study said:
People with ME should be able to seek the advice of a specialist service close to their homes. We were surprised by the lack of services and access to services that our survey revealed. Even if the local Trust provides a service, some housebound patients will never get to use it. Many, very ill patients are going without."
