Were you looking for information about Cholesterol? Cholestral is a common misspelling of cholesterol.
Cholesterol is a waxy substance that is found in each cell of the human body. The body uses cholesterol to hold cells together and to make hormones, vitamin D, and substances that help you digest foods. Although the body needs cholesterol to function properly, too much of this substance can cause problems. A simple blood test can determine if your cholesterol level is too high. In most cases, healthcare providers recommend a blood cholesterol test every five years -- more often if you have risk factors for heart disease.
