Modern medicine provides clear mechanisms for elevated cholesterol levels that align meaningfully with the principles in the Donguibogam. The primary fats in the bloodstream include low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides. When this balance is disrupted and low-density lipoprotein cholesterol or triglycerides rise excessively, the condition is diagnosed as hyperlipidemia or dyslipidemia.
The central issue is that excess lipids gradually collect along the vascular wall, forming sticky plaque. What begins as microscopic damage progresses over time into larger, harder plaques that narrow and stiffen the arterial lumen. This process is known as atherosclerosis, similar to old water pipes that narrow as rust and deposits accumulate inside. As blood vessels narrow, blood flow is hindered, and vital organs such as the heart and brain cannot receive adequate oxygen and nutrients.
The role of inflammation warrants particular attention. Modern research demonstrates that inflammatory processes play a central role in vascular damage and plaque formation. When vascular endothelial cells suffer microscopic injury, the immune system responds to repair them. However, lipid components such as low-density lipoprotein cholesterol interfere in this healing cascade, perpetuating inflammation and causing the plaque to expand. This sustained inflammatory state also affects the nervous system and endocrine system, increasing stress hormone release, raising blood pressure, and contributing to systemic health decline.
Such arteriosclerosis is the primary driver of cardiovascular conditions like angina pectoris and myocardial infarction. If vessels leading to the brain become occluded or rupture, a stroke—either cerebral infarction or cerebral hemorrhage—can occur, endangering life or leaving lasting sequelae. In the lower limbs, narrowed vessels cause peripheral artery disease, which impairs walking and, in severe cases, can lead to tissue loss. These conditions show that elevated cholesterol is not an isolated laboratory reading, but a warning that the entire vascular network is compromised.
While genetic predisposition plays a role, most cases of hyperlipidemia develop in close connection with lifestyle factors such as dietary choices, physical inactivity, smoking, alcohol consumption, and chronic stress. Diets high in calories, fats, and simple sugars directly drive up triglycerides and low-density lipoprotein cholesterol. Chronic stress also disrupts autonomic nervous system regulation and hormone balance, worsening blood pressure, blood glucose, and lipid profiles.
Modern clinical practice prioritizes lifestyle modifications—including dietary changes, regular exercise, smoking cessation, and moderate drinking—as the foundation for managing hyperlipidemia, adding pharmacotherapy when necessary. Long-term vascular health depends not only on lowering numbers through medication, but also on cultivating habits that allow the vessels to maintain their own integrity. Just as the Donguibogam emphasized the smooth flow of blood, modern medicine underscores the need for comprehensive systemic care.
