Cholesterol Vs. LDL Cholesterol

Cholesterol, a fatty substance produced by the liver and vital for normal body functioning, is divided into two distinct types that must be regulated to maintain good health.

History

• Though it had been isolated as early as 1770, research on cholesterol composition only began around 1903. By the early 1930s, additional evidence from X-ray analysis discovered the correct structure of the cholesterol molecule. In 1951, American chemist Robert B. Woodward synthesized cholesterol beginning with simple compounds.

Types

• HDL (high density lipoprotein) cholesterol is commonly called the "good" type because it helps keep cholesterol from building up in the arteries. LDL (low-density-lipoprotein) cholesterol is called the "bad" type because it increases the risk of heart attack and stroke.

Effects

• When there is too much LDL cholesterol in your blood, it builds up in the walls of your arteries. Eventually, the arteries become narrowed and blood flow to the heart is slowed or blocked, causing chest pain. If the blood supply to a portion of the heart is completely blocked, the result is a heart attack.

Prevention/Solution

• To maintain high HDL cholesterol levels and lower LDL levels, avoid smoking, maintain a healthy diet low in saturated fats and cholesterol, and get at least 30 to 60 minutes of exercise each day. Schedule regular checkups with your doctor to monitor your HDL and LDL levels.

Considerations

• An inherited genetic condition called familial hypercholesterolemia can result in high LDL cholesterol levels and might result in a heart attack at an early age. In this case, one should seek the advice of and treatment by their physician.
