Chronic fatigue is a complex and often misunderstood condition characterized by extreme fatigue or tiredness that persists for more than 6 months and does not improve much with rest. The key aspect that defines chronic fatigue is that the fatigue causes significant impairment in daily functioning and cannot be fully explained by an underlying medical condition. Some key facts about chronic fatigue:
- It affects both physical and mental functioning. Those suffering from chronic fatigue experience muscle pain, headaches, poor concentration and memory, and sleep issues on top of extreme tiredness.
- The exact cause is unknown. Contributing factors may include viral infections, immune system abnormalities, endocrine dysfunction, and central nervous system impairments.
- There are a few names used to describe chronic fatigue disorders including myalgic encephalomyelitis (ME), systemic exertion intolerance disease (SEID), and chronic fatigue syndrome (CFS). These terms are sometimes used interchangeably.
- Pacing activities and rest periods
- Stress reduction techniques like meditation
- Gradual increases in exercise to avoid post-exertional malaise
