Pathophysiology. Hypercholesterolemia, an elevation of total cholesterol (TC) and/or low-density lipoprotein cholesterol (LDL-C) or non-high-density lipoprotein cholesterol (HDL-C) (defined as the subtraction of HDL-C from TC) in the blood, is also often referred to as dyslipidemia, to encompass the fact that it might be accompanied by a decrease in HDL-C, an increase in triglycerides, or qualitative lipid . Difficulty in breathing or breath shortage is a noticeable symptom of high cholesterol levels. The three cardinal features of familial hypercholesterolemia are: 1) a selective elevation in the plasma level of one cholesterol-carrying lipoprotein, low density lipoprotein (LDL); 2) a selective deposition of LDL-derived cholesterol in macrophage-like scavenger cells .

The classical genetic disorder is familial hypercholesterolemia due to mutations in the LDL-receptor gene resulting in LDL-C greater than 190 mg/dl in heterozygotes and greater than 450 mg/dl in homozygotes. 1. If you are overweight, you most likely have a higher level of triglycerides. Common causes of high cholesterol include: Eating a diet high in saturated fat and trans fat, often found in animal meat and processed foods.
