Why have my TC and LDL levels been continuously high for the last two years?
Genetic predisposition, a diet heavy in saturated fats, being overweight, or inactivity are common causes of persistently high TC and LDL. Alcohol consumption, hypothyroidism, diabetes, and irregular medication use can all maintain high levels. A physician can determine the cause and modify long-term lipid-lowering therapy, food, and lifestyle accordingly.
