Cholesterol

What are  LDL and HDL?

LDL and HDL are lipoproteins that monitor the cholesterol in the bloodstream. LDL brings cholesterol into the bloodstream and HDL brings cholesterol to the liver to be broken down

How do LDL and HDL differ structurally and functionally?

LDL is less dense than HDL because it has room for more cholesterol. HDL is also typically smaller than LDL. LDL bring cholesterol into the bloodstream from the Liver. HDL brings cholesterol to the Liver from the bloodstream.

Why do doctors monitor the concentration of LDL and HDL in patients' blood?

Doctors monitor the concentration of LDL and HDL because typically when you have high LDL and low HDL, there is a health issue and/or a possible blockage of an important vessel.

How are the concentrations of LDL and HDL associated with the risk of heart disease and associated disorders?

If you have high levels of LDL and low levels of HDL, you are at high risk of heart disease because LDL is most likely clogging or working to clog your arteries without being balanced out by the HDL which works to unclog arteries.

What other molecules in a patient's blood are monitored along with LDL and HDL?

Triglycerides and Cholesterol are monitored along with LDL and HDL.

What do results of a cholesterol test mean? How do patients interpret each value?

When you receive your test results of a cholesterol test, there should be four numbers: total blood cholesterol, HDL levels, LDL levels, and triglycerides. Total blood cholesterol is LDL and HDL with twenty percent of your triglycerides. A good cholesterol value would be less than 180mg/dL. HDL levels is best when high. LDL levels are best kept low. Triglycerides are best kept low.

What can patients do to change the levels of HDL and LDL in their blood?

Patients can learn the foods high in HDL and LDL and either avoid them or start eating more of them depending on their situation. Foods containing high amounts of HDL are oils, fish, and pistachios. Foods containing high amounts of LDL are dairy, lean protein, processed food, and food containing trans fat.

How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health?
