Modern medicine can understand the phlegm-fluid described in the Donguibogam as a comprehensive concept encompassing diverse symptoms rather than a single disease entity. In particular, it shares much in common with the discomfort experienced by those whose symptoms closely resemble hypothyroidism but fall into the normal range on lab tests. In such cases, reinterpreting the concept of phlegm-fluid from a modern perspective can help make sense of these symptoms.
For every single cell in our body to actively produce energy and carry out metabolic activity, thyroid hormone must be supplied in adequate amounts. However, even if thyroid levels are normal, if thyroid hormone does not work properly inside cells, or if there is a subtle problem in the function of the receptors that transport this hormone into cells, one can experience symptoms identical to thyroid hypofunction despite normal blood tests. This is sometimes described as subclinical hypothyroidism or peripheral thyroid hormone resistance.
In this state, our body's metabolic rate drops overall, much like a car whose engine runs only at low speed. Because energy is not sufficiently produced, chronic fatigue and lethargy set in, and the ability to maintain thermoregulation declines, making one feel cold more easily. Furthermore, the fluid and waste excretion functions of the kidneys and lymphatic system become sluggish, leading to swelling, and unnecessary body fat easily accumulates, leading to weight gain. This edema tends to be worse in the morning and improve slightly in the afternoon. Pillow marks lingering on the face for a long time after waking can also occur for this reason.
Furthermore, a chronic inflammatory state or insulin resistance can also be viewed as modern expressions of phlegm-fluid. Just as sticky phlegm clogs circulation, excessive glucose and insulin in the blood cause inflammation in the vascular endothelium and hinder microcirculation, impairing the supply of oxygen and nutrients to cells. As a result, brain function is affected, and symptoms such as the cloudy head known as brain fog, impaired concentration, and memory impairment can appear, much like walking through dense fog. If blood flow and nutrient delivery to brain cells are impaired, neurotransmitter balance is also affected, which may be accompanied by mood swings or low mood.
Ultimately, phlegm-fluid in the Donguibogam goes beyond the simple pooling of fluid and can be understood as a complex state encompassing overall metabolic hypofunction, immune responses, and nervous system imbalances. Rather than assuming everything is fine simply because test values are normal, it is helpful to pay attention to subtle bodily signals and look for foundational improvements through lifestyle habits. Our bodies communicate their needs honestly.
