Multifactorial: Chronic fatigue syndrome is a multifactorial consequence of hormonal, immune system and nervous system dysfunction resulting from genetic predispositions and dietary and environmental insults. These factors impair the patient's ability to produce energy and they end up chronically fatigued. Poor diet, suboptimal sleep, food and other allergies contribute.
