Charlie has a blood test that shows a normal level of LDLs but an elevated level of HDLs in his blood. Since his family has a history of cardiovascular disease, he wonders if he should modify his lifestyle. What would you tell him?
What will be an ideal response?
Based just on the information given, Charlie would appear to be in good health, at least relative to his diet and
exercise. Problems are associated with elevated levels of LDLs, which carry cholesterol to peripheral tissues and
make it available for the formation of atherosclerotic plaques in blood vessels. High levels of HDLs indicate that a
considerable amount of cholesterol is being removed from the peripheral tissues and carried to the liver for
disposal. You should encourage Charlie not to change, and keep up the good work.
