Q: What is cholesterol?
A: Cholesterol is a fatty substance present in most
meaty foods and some vegetables. In normal amounts
it is an important building block of bile acids,
which help digestion, and steroid hormones. In the
blood, cholesterol is found in particles containing
both lipids (fats) and proteins; hence they are
referred to as lipoproteins. High cholesterol levels,
however, are associated with health problems, including
increased risk of heart disease and stroke.
Q: What is LDL?
A: Often called "bad cholesterol," LDL
is the main source of cholesterol build-up and
blockage in the arteries.
Q: What is HDL?
A: Often called "good cholesterol,"
HDL helps keep cholesterol from building up in
the arteries.
Q: What are the warning signs of high cholesterol?
A: This is what makes high blood cholesterol levels
so frightening; there are no symptoms! Many people
are unaware that their cholesterol levels are
too high. Only by having a blood lipid test will
you know if your cholesterol is within a healthy
range.
Q: What is a healthy cholesterol level?
A: A total cholesterol level less than 200 mg/dL
is best with LDL levels less than 100 mg/dL. High
cholesterol would be 240 mg/dl and above total
cholesterol with LDL levels above 130 mg/dL.
Q: What can I do to lower my cholesterol?
A: Exercise regularly, eat a low saturated fat,
low-cholesterol diet and keep weight at a healthy
level.
Q: Should I worry about my children's cholesterol
levels?
A: Yes, it is never too early to keep an eye on
your child's cholesterol level. A new study has
uncovered that high cholesterol in childhood has
a direct effect of cholesterol levels in adulthood.
In fact, those with normal level may have an increased
risk in as little as five years. Fast food and
children's snacks high in saturated fat often
cause initial high cholesterol and these eating
habits are continued as the child matures. Although
heredity is a common cause of high cholesterol
at a young age, it can be avoided with proper
nutrition and exercise.
Q: Does gender affect my cholesterol level?
A: One out of every two men and every three
women will develop heart disease in the course
of their lives. However, women are less likely
than men to seek or receive treatment for high
cholesterol.
