Understanding Severe ME

“Severe and very severe ME/CFS represents one of the most profound states of disability found in medicine.” – Bateman Horne Center, USA

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a serious, multisystem disease. At its most severe, it causes extreme physical, cognitive and sensory dysfunction—leaving people housebound or bedbound, and often unable to tolerate light, sound, or even touch.

Around 25% of people with ME/CFS experience severe or very severe symptoms. These individuals may:

  • Be unable to speak or tolerate conversation
  • Need assistance with all aspects of daily care
  • Experience intense pain and energy loss, gastrointestinal issues, and orthostatic intolerance
  • Be unable to tolerate standard medical environments or interventions

Despite their level of disability, they are frequently overlooked by healthcare systems and society.

Resource Guide for Clinicians

This Resource Guide from the World ME Alliance is intended for use in crisis situations — particularly when hospitalisation is being considered — and can be handed to clinicians and healthcare providers by patients or carers. It is designed to support self-advocacy when people with Severe ME may be too unwell to speak for themselves, and to guide healthcare professionals toward safer, more appropriate care.

Through this concise and practical document our goal is to help give voice and agency back to those who are often left unseen and underserved by healthcare systems.
