Jim Shannon, Democratic Unionist MP for Strangford, tabled a written question that asked the Secretary of State for Health what estimate he has made of the number of people in each age group who have suffered from chronic fatigue syndrome in each of the last five years.
In a written answer supplied on 25 March 2015, Liberal Democrat Minister of State of Health Norman Lamb, replied:
No assessment has been made of the number of people in each age group who have suffered from chronic fatigue syndrome in each of the last five years. With the exception of cancer, there is no comprehensive central record of disease diagnosis for any condition. In 2007 The National Institute for Health and Care Excellence produced the clinical guidance ‘Chronic fatigue syndrome/myalgic encephalomyelitis (or encephalopathy): Diagnosis and management of CFS/ME in adults and children’, which estimates that the annual prevalence is approximately 4,000 cases per million of the population.
