In brief: Likely The Cause
Patients suffering from anorexia nervosa restrict their intake leading to protein-energy malnutrition.
This in turn causes muscle dysfunction and finally exercise intolerance. In one study all subjects showed impaired muscle function on strength and exercise measurement. 50% of patients showed nerve damage and tissue biopsies showed muscle damage at the microscopic level.
