Action for M.E is an organisation led by people with M.E., for people with M.E.
M.E (Myalgic Encephalomyelitis) affects an estimated 250,000 men, women and children in the UK.
Severe and persistent fatigue or exhaustion most, or all of the time, is one of the main symptoms of M.E. This feels very different from ordinary tiredness.
Simple physical or mental activities, or combinations of activities, can leave people with M.E feeling utterly debilitated. They can also experience an increase in other symptoms.
The impact of this may be felt straightaway but it can typically take a day or two to kick in and is not significantly improved by resting. This is a key feature of the way M.E affects people, and is known as post-exertional malaise (sometimes called 'payback').
