Key findings

• Muscle cells from people with ME/CFS are less able to use glucose as a fuel to produce energy
• This impairment in energy production may underlie the muscle fatigue that is characteristic of the illness
• These results help narrow down where in the metabolic pathway the abnormality occurs

Background

Muscle fatigue is among the most common symptoms experienced by people with ME/CFS, with a huge impact on their quality of life, and it is a key element of existing ME/CFS diagnostic criteria. So it makes perfect sense to focus research on the biological mechanisms underlying this symptom.
