What is ME/CFS?

ME/CFS is a relatively common condition with symptoms that can be as disabling as other chronic conditions.

This can have a profound impact on the person, as well as their family.

It affects people of all ages.

Extreme fatigue most of the time is the main symptom – this is very different from ordinary tiredness.

Simple mental or physical tasks can leave the person feeling exhausted and struggling to function.
