The state of M.E. in the United Kingdom

Myalgic Encephalomyelitis — often written ME/CFS — is a chronic, complex neurological disease recognised by the World Health Organization. It affects multiple body systems, including the nervous and immune systems and the body's ability to produce energy. It is not the same as ordinary tiredness, and it does not improve with rest in the way that everyday fatigue does.

The defining feature is post-exertional malaise (PEM): a disproportionate worsening of symptoms after even minor physical, mental or emotional effort, often delayed by a day or two and lasting days, weeks or longer. Alongside PEM, people live with unrefreshing sleep, cognitive dysfunction known as "brain fog," pain, and problems regulating heart rate, temperature and blood pressure.

An estimated 1.35 million people in the UK live with ME — and it is widely recognised the true number may be much higher. That figure rose sharply following the COVID-19 pandemic, as a significant proportion of people with Long Covid meet the criteria for ME/CFS. It affects people of every age and background, including children, and is around three times more common in women than in men.

Roughly a quarter are severely affected — largely housebound or bedbound, unable to work, study or care for themselves, and dependent on others for basic daily needs. The very severely affected may be unable to tolerate light, sound, touch or even chewing, and can require tube feeding.

Spread across the country, the numbers land in every surgery. On these estimates, the average GP has between 13 and 26 patients with ME on their list right now — a caseload comparable to many conditions that have dedicated pathways, clinics and funded training.

ME has almost none of that. Most GPs receive no meaningful training in the disease, have no clear referral pathway to send patients down, and were taught — through years of since- discredited guidance — to view it through a psychogenic model. That outdated cognitive bias persists long after the evidence for it collapsed and NICE withdrew graded exercise therapy in 2021.

The result is a quiet, distributed failure: thousands of patients in every region, sitting with clinicians who want to help but have neither the tools nor a place to send them.

In 2021, the National Institute for Health and Care Excellence (NICE) published an updated guideline, NG206. It was a watershed: it formally recognised ME/CFS as a serious medical condition, and — crucially — withdrew its previous recommendation of graded exercise therapy, which many patients reported had made them permanently worse.

Yet guidance on paper has not translated into care on the ground. Specialist services are sparse and unevenly distributed; many regions have none at all. People with severe ME, who are too unwell to attend clinics, frequently fall through the cracks entirely. Waiting lists are long, GP knowledge is inconsistent, and patients still report disbelief and being told their illness is psychological.

For decades, ME received a tiny fraction of the research funding given to conditions of comparable scale and severity. That is beginning to shift. DecodeME, the world's largest genetic study of ME/CFS, analysed DNA from tens of thousands of people and in 2025 reported genetic signals associated with the disease — early but concrete evidence of its biological basis.

Momentum is building elsewhere too: growing overlap with Long Covid research, the launch of a cross-government delivery plan for ME/CFS in England, and a louder, better-organised patient and advocacy community. The funding gap, however, remains wide.

In 2024, the inquest into the death of Maeve Boothby O'Neill, a 27-year-old who died from severe ME in Exeter, became the first in England to formally examine ME as a cause of death. The coroner concluded she died of malnutrition caused by her illness.

The coroner issued a Prevention of Future Deaths report warning of a national lack of specialist beds, training and care for people with severe ME. It put into the public record what patients and families had said for years: the system is not equipped to keep the most severely ill safe.

The direction is clear, even if progress is slow. Advocates and clinicians broadly agree on the priorities:

• Sustained, ring-fenced biomedical research funding proportionate to the scale and severity of the disease.
• Specialist services in every region — including pathways that can actually reach housebound and bedbound patients at home.
• Mandatory, up-to-date ME education for doctors, nurses and allied health professionals.
• Inpatient care that is safe for people with severe and very severe ME, as the Maeve inquest demanded.
• An end to the stigma and disbelief that still surround the diagnosis.

Awareness is the first step. Understanding what ME actually is — and how badly the current system serves the people living with it — is what makes change possible.
