As time has gone on, the energy production issue in chronic fatigue syndrome (ME/CFS) has become better and better documented as researchers take different slants on it.
Take the whole body energy production tests. Workwell’s two day cardiopulmonary exercise tests (CPETs) have documented the damaging effects that exercise one day has on ME/CFS patients’ ability to produce energy the next day. Harvard pulmonologist David Systrom’s invasive CPETS have located multiple areas of deficiency (poor oxygen uptake, microcirculatory problems, reduced preload) in energy production. From Katarina Lien in Norway, to Betsy Keller in the U.S., to Vermeulen and Visser in the Netherlands, many studies suggest that fundamental problems producing energy exist. (We await the results of one of the most intriguing studies: Avindra Nath’s CPET/metabolic chamber study.)
