Conditions which have symptoms in common with ME/CFS

There are a variety of hormonal (e.g. hypothyroidism), rheumatological (e.g. lupus/SLE), neurological (e.g. multiple sclerosis), infective (e.g. Lyme disease and hepatitis B/C virus) and gastrointestinal (e.g. coeliac disease) conditions which can all produce very similar symptoms to those found in ME/CFS. This is why it is so important for doctors to take a detailed clinical history from anyone suspected of having ME/CFS (especially when there are atypical features present) and arrange appropriate investigations if the diagnosis is in doubt.
