It won't make you feel sick. In fact, you may feel fine. But when your cholesterol sneaks up beyond a desirable level, it puts you at increased risk for a heart disease, heart attack, stroke and other cardiovascular diseases. The liver makes most of the body's cholesterol to help carry fat to parts of the body that need fat for energy and repairs, or to fat storage sites such as hips or belly.
Some cholesterol also comes from foods high in cholesterol, such as eggs.
There are different types of cholesterol in the body. Each has a very different job in the body. VLDL carries fat from the liver to other parts of the body. VLDL becomes LDL after it unloads fat. This buildup of LDL can cause narrowing of the blood vessels.
