Dyslipidemia
is a complex word for what most of us know as a condition of high
cholesterol. It is not an easy story to tell and the arithmetic
is even more difficult. First, the translation…dys – means
disorder; lipid – a fat-like substance, and emia –
a blood related issue. Dyslipidemia is an imbalance of fat-like
substances in the blood.
What is all the fuss
about? A serious hardening characteristic of arteriosclerosis is
caused by a build up of fatty deposits are made mostly of cholesterol.
Advanced stages of this plaque build up can cause a diminished blood
supply to the heart. Heart disease is still the major killer in
the United States and individuals with blood cholesterol levels
above 240 are three times more likely to suffer a heart attack than
those whose cholesterol level is under 180. Doctors differ on the
actual “safe” cholesterol level. Many conventional practitioners
feel 220 to be an acceptable level and there are doctors who feel
very strongly about maintaining a blood cholesterol level of 160.
What doctors do agree upon is - lower is better. Unfortunately,
for many, the first warning sign of trouble is the dreaded heart
attack, and one third of these are fatal. Lowering cholesterol levels
is clearly the way to prevent problems.
Sound simple? Not so
fast! Not all cholesterol is “bad”. One type of cholesterol signals
problems while another kind of cholesterol can actually prevent
heart disease. Triglycerides and cholesterol are the lipids of primary
concern. Oils and fats in the foods we eat are stored in fat cells
until the body converts that to heat energy. Cholesterol is produced
in your liver and intestines. The food you eat also contributes
to the overall supply of this wax-like substance. Triglycerides
and cholesterol must be transported though the blood stream by proteins
called low-density lipoproteins (LDL). This new LDL cholesterol
(“bad cholesterol”) can result in cholesterol deposits on the artery
walls if the cholesterol levels are too high. High-density lipoproteins
carry HDL cholesterol, the “good cholesterol”, which is thought
to remove excess “bad cholesterol” from cells and back to the liver
for reuse or broken down and eliminated from the body. An easy way
to remember the good from the bad is to keep HDL high and LDL low.
