What Causes High Cholesterol?

Generally, elevated cholesterol levels may result from prolonged high-fat dietary habits, physical inactivity, primary (familial) hypercholesterolemia, hypothyroidism, or fatty liver disease. If symptoms arise, prompt consultation and treatment at a reputable hospital are recommended. A detailed analysis follows:

1. Prolonged High-Fat Diet

Long-term consumption of organ meats, fatty cuts of meat, and fried foods leads to excessive exogenous cholesterol intake—exceeding the body’s metabolic capacity—and consequently elevates serum cholesterol levels. Adopting a low-fat diet routinely, increasing intake of dietary fiber–rich foods, and reducing consumption of high-cholesterol foods are advised.

2. Physical Inactivity

Extended periods of sedentary behavior slow down overall metabolism and reduce lipid breakdown efficiency, resulting in excess cholesterol accumulation. Engaging daily in aerobic exercises—such as jogging or brisk walking—enhances lipid metabolism and helps maintain normal metabolic circulation.

3. Primary Hypercholesterolemia

This condition involves dysregulation of lipid metabolism, leading to increased hepatic cholesterol synthesis and consequent abnormal elevation of blood lipid parameters. Treatment may include prescription medications such as atorvastatin calcium tablets, pravastatin sodium tablets, or ezetimibe tablets, under medical supervision, along with regular lipid profile monitoring.

4. Hypothyroidism

Inadequate thyroid hormone secretion slows systemic metabolism and impairs cholesterol catabolism, causing lipid accumulation. Management may involve prescribed medications—including levothyroxine sodium tablets, thyroid tablets, or Bu Zhong Yi Qi Wan (a traditional Chinese medicine formulation)—combined with regular sleep patterns and moderate exercise.

5. Fatty Liver Disease

Excessive fat deposition in hepatocytes compromises liver function, disrupting normal lipid metabolism and impairing cholesterol processing and elimination. Pharmacotherapy—under physician guidance—may include silybin capsules, polyene phosphatidylcholine capsules, or diammonium glycyrrhizinate capsules. In severe cases, liver biopsy and targeted therapeutic interventions may be required.

In daily life, maintaining a low-fat, light diet; avoiding prolonged sedentary behavior; engaging regularly in physical exercise; undergoing routine health check-ups—including lipid profile and liver function tests; and promptly and appropriately managing metabolic disorders are essential for long-term health.
