LDL

(ĕl′dē′ĕl′)

A lipoprotein with a relatively high concentration of lipids and low concentration of protein that incorporates cholesterol and transports it to cells. High levels are associated with an increased risk of atherosclerosis and coronary artery disease. Also called LDL cholesterol.

Patient discussion about LDL

Q. How can I increase my HDL cholesterol levels? My Doctor told me that my cholesterol levels are not good and that I should lower my LDL and higher my HDL. I understand how to lower the cholesterol, but how can I increase the HDL?

A. a good way is to eat boiled fish, and instead of regular oil, add olive oil to your salad.

Q. Improving High Triglycerides I take Tricor for high triglyceride levels; I have a healthy level of total cholesterol, with low LDL, very good HDL. I am now being treated for hypothyroidism, but my doctor says that it's also genetic (I had almost the exact same level number as my brother). How can I work to get my triglycerides under control?

A. High level of triglycerides are generally both genetic and diet related. If you are consuming a high fat containing diet then your level of triglycerides will be increased. On the other hand, regardless of your good cholesterol levels, if you start lowering the amount of fat in your food (less oil, less sweets, less red meat) and combine it with physical activity you can lower your triglycerides level, especially if you are already on medications.

Q. Does wight loss lowers cholesterol? I'm 5'5, 175 lbs, 40 years-old man. After my doctor found that I have high LDL cholesterol, I was advised to try to lower my weight in order to reduce my cholesterol levels. Otherwise I'll have to start taking medications. Can it really do something? As far as I know, cholesterol level are pretty much a genetic thing, and one can be very thin but still have high cholesterol levels.

A. One of the best things you should do is to take a good multivitamin multimineral supplement. And of course, changing your lifestyle. Supplementing your diet with vitamins can help you reduce your LDL cholesterol levels and increase HDL. Also, increase your intake of omega 3 fatty acids, but make sure that you know the source they are from before taking them.
