Lipoproteins that include chylomicrons, vldl, LDL and HDL - what do each of these do?

Lipoproteins that include chylomicrons, vldl, LDL and HDL - what do each of these do?

Common denominator: They all transport different types and sizes of fats in your blood. Fats are insoluble in blood (literally like "oil mixing with water") and they must be transported inside protein molecules. The combination of fat and protein is called a "lipoprotein" molecule ...Read more

Lipoprotein (a) was at 355. Cholesterol 180. Hdl 38 LDL 124 and trig127. Started taking 1000 mg of niacin will this lower lp(a) and exercising 3xweek?

Lipoprotein (a) was at 355. Cholesterol 180. Hdl 38 LDL 124 and trig127.  Started taking 1000 mg of niacin will this lower lp(a) and exercising 3xweek?

May be: Niacin may improve the lipid profile but it has not been proven to improve chances of heart attack or stroke. Also, they have several side effects and is hard to get people to take them long term i rather you do more exercise (5-6 times/week), be in the best possible shape, loose a few pounds if you are overweight. That will increase the good cholesterol (HDL) and lower the bad. Your tg are ok. ...Read more

Why are low-density lipoproteins (ldl) considered unhealthy?

Why are low-density lipoproteins (ldl) considered unhealthy?

Blood LDL Level: LDL is a particle that carries cholesterol in the blood. Increased numbers of circulating LDL particles drive their entry into the walls of arteries where they promote and accelerate atherosclerosis (hardening of the arteries), and subsequently increase risk for heart attack, stroke and premature death. Lowering LDL can reduce this risk. ...Read more

What is the difference between HDL (high-density lipoprotein) and LDL (low-density lipoprotein)?

What is the difference between HDL (high-density lipoprotein) and LDL (low-density lipoprotein)?

Big difference: Ldl, when found in high concentrations in the blood, can enter your artery walls and initiate an inflammatory reaction that culminates in the development of atherosclerosis, plaque formation in the arterial wall. Hdl had many functions. If HDL is functioning well it can help to prevent atherosclerosis. One of its major functions is to remove cholesterol from the arterial wall. ...Read more

Is it ok to take niacin 1000mg and lexapro (escitalopram)? The reason for such high niacin my LDL is 124 and my lipoprotein (a) little a is 355nmol normal range <75

Yes: Niacin should not affect lexapro's ability to be absorbed the way it affects cholesterol's ability to be absorbed in the digestive tract. However, if you are concerned that it might, you can take one in the morning and one at night, which will ensure separate and full absorption. Good luck and be well : ). ...Read more

How to decrease your ldls (low density lipoproteins)?

How to decrease your ldls (low density lipoproteins)?

Lower blood sugar : High cholesterol is linked to high Insulin levels and hormonal changes as a result of it. I suggest not mixing animal protein with starch but veggies. Also cardio and yoga and fish oil or flax seed oil to raise your good cholesterol (hdl). Also get a particle size to see if your dense LDL is high or the larger size. ...Read more

Ct angio score 0, dad heart attack at 50, stress echonormal, BMI 21, hdl 34, lipoprotein A 5, ldl 115, triglyceride 75, help please? What to do???????

Optimise your lipids: AT your young age of 26, if CT angio score is 0, that bodes well for you, it means you have no significant visible calcified plaque in coronary arteries. Having said that, atheroslerosis leading to heart disease is a cumulative process, so very important that you modify your risk factors through lifestyle changes: raise HDL >45 atleast. Exercise regularly (even walk 30 min daily), eat salmon, av ...Read more
