Cholesterol By: Gage Ward
1) What are LDL and HDL? -LDL: (Low Density Lipoprotein) Is called bad cholesterol because having too much can lead to plaque buildups which lead to heart attack and stroke -HDL: (High Density Lipoprotein) Is called good cholesterol because it acts as a sort of garbage truck, carrying LDL to the liver so it can be disposed of. Having a lot of HDL is a good thing because it reduces risk of plaque build up, and in turn, heart attack and stroke.
2) How do LDL and LDH differ, functionally and structurally? -LDL: Clogs arteries, and leads to plaque buildups witch leads to heart attack, stroke. Looks like small, thick, hard deposits. -HDL: Carries LDL to the liver for disposal. Looks like large flexible deposits.
3) Why do doctors monitor levels of LDL and HDL in patients blood? -Because if a patient has high LDL, then they are at risk for other complications. If a patient has high HDL, then they are less at risk for complications.
4) How are the concentrations of LDL and HDL associated with the risk of heart disease and other associated risks? -LDL raises your risks, HDL lowers those risks.
5) What other molecules are monitored in a cholesterol test other than LDL and HDL? -The body's triglycerides are also monitored.
6) What do the results of a cholesterol test mean? How do patients interpret each value? -The results of a cholesterol test tell the doctors and patients their cholesterol, and if they need to make changes to their diet, take medications, or just stay the same.
7) What can patients do to change the levels of LDL and HDL in their blood? -You can change your diet, and exercise habits, or you can take medications to control your cholesterol.
8) How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health? -The Good: Unsaturated fats improve blood cholesterol, ease inflammation, and stabilize heart rhythms.
-The Bad: Saturated fats lower good cholesterol, raises triglycerides, and causes insulin resistance.
-The Ugly: Trans fats raise LDL, lower HDL, and fuel inflammations.
