About chronic fatigue syndrome
CFS/ME is a condition that causes severe tiredness that doesn’t improve after rest. It can happen after an infection, or less commonly after trauma such as an accident or an operation.
CFS/ME is a genuine, long-term debilitating condition. However, there is uncertainty around the causes and the symptoms people have as they can vary widely.
CFS/ME is more common in women than men, and you’re more likely to develop the condition as you get older. It can affect children, although it’s unlikely to affect children under 10, it usually affects children aged 13 to 15 years.
Around 250,000 people in the UK have CFS/ME. The condition affects people in different ways. If the symptoms of the condition are mild, people can carry on with work or study but may have to give up leisure and social activities to spend the weekend resting. If symptoms are severe, people can become seriously disabled and housebound.
