Hyperlipidemia is a condition where there is too much cholesterol in the blood. Cholesterol is normally produced by the liver and is essential for cell function, but excess bad cholesterol (LDL) can accumulate in the arteries and cause health issues. Hyperlipidemia often has no symptoms, and is detected during routine blood tests or after cardiovascular events like heart attacks. To reduce cholesterol levels, one should avoid foods high in saturated and trans fats like red meat, butter, fried foods, and tropical oils.
