Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a complicated disorder characterised by extreme fatigue that lasts for at least six months and that can’t be fully explained by an underlying medical condition. The fatigue worsens with physical or mental activity, but doesn’t improve with rest.
Common symptoms of ME/CFS are listed by the NHS as:
- feeling extremely tired all the time – you may find it very hard to do daily activities
- still feeling tired after resting or sleeping
- taking a long time to recover after physical activity
- problems sleeping, such as waking up often during the night
- problems with thinking, memory and concentration
