Indeed, consumptive disease in Korean medicine bears a striking resemblance to what modern medicine terms chronic fatigue syndrome. Chronic fatigue syndrome is characterized by extreme fatigue lasting at least six months. Beyond mere tiredness, it clings persistently enough to impair daily life significantly and does not resolve with adequate rest. Although its exact cause remains unclear, a complex interplay of various factors—including stress, immune dysfunction, viral infections, and neuroendocrine system imbalances—is considered to be involved.
Neurologically, hypofunction in specific brain regions, particularly those involved in fatigue and cognitive function, is observed in patients with chronic fatigue syndrome. Abnormal cerebral energy metabolism or problems in the regulatory function of the autonomic nervous system connecting the brain and body can destabilize basic physiological functions such as heart rate, blood pressure, and digestion. Impaired concentration and memory impairment, often called brain fog, are hallmark symptoms of decreased brain function. Many patients describe feeling as though a fog has settled over their minds, making them feel spaced out and struggling to think clearly.
Endocrinologically, abnormalities in the secretion of cortisol, the stress hormone, are frequently found. The body secretes cortisol to cope with stressful situations; however, under chronic stress, this hormonal system can become overactive or, conversely, become depleted and fail to respond properly. This cortisol imbalance disrupts sleep patterns, lowers immunity, and serves as a major driver of overall decline in physical function. This may explain why your body feels heavily weighed down no matter how much you rest, and why sleep fails to leave you refreshed.
Furthermore, chronic fatigue syndrome impacts the immune system. Immune dysfunctions, such as elevated pro-inflammatory cytokine levels or decreased natural killer cell activity, are observed, which can make the body more vulnerable to viruses or bacteria and trigger inflammatory responses from minor stimuli. Ultimately, underlying immune imbalances may manifest as generalized pain or low-grade fever.
In conclusion, chronic fatigue syndrome can be understood as a complex disorder arising from tangled physiological and biochemical issues, including mitochondrial dysfunction—the body's cellular energy powerhouse—gut dysbiosis, and chronic inflammation. Rather than dismissing it merely as a psychological issue, it represents a crucial signal requiring an examination of the body's overall systems from an integrative perspective.
