how cholesterol affects body ?

Answer 1

there are two different sorts of cholesterol,,,,,, bad and good.
The bad stuff starts to line your arteries so that means that your blood supply is reduced, and then your heart has to pump faster to get all the blood it needs around your system.
The good stuff is needed for survival.
no cholesterol is A Bad Thing.
Good stuff is LDL and the villianous stuff is called HDL (BOOOOOOoooo........

Answer 2

Let's see if I can put this simply: Cholesterol is good for you, but it is also bad for you. The reason it is good for you is because it is used in many, many biological reactions to produce hormones and bile salts (among other things). It is used directly to store fats and to maintain the fluidity of our cell membranes. We need it to live.

Cholesterol is made by the body, but can also be taken in from the diet. It is found in the blood in large micelle lipoproteins - balls of lipids and proteins that travel through the bloodstream. The density of these proteins can give you some clue to where they come from, and what their purpose is in the body. The bottom line is, LDL (low density lipoproteins) are produced when you're body has too much cholesterol. It represents the cholesterol that is being shipped by your liver to your cells for storage (HDL is the opposite; IDL, VLDL and Chylomycrons get much more complicated, so I'll ignore those for now).

The problem with having high cholesterol levels (mainly LDL) is that they are prone to oxidation (i.e. they go 'bad'). When an LDL molecule goes bad, it gets trapped underneath layers of cells in your blood vessel. The blood vessels start complaining, sending white blood cells to the area. A white blood cell (specifically, a macrophage) comes by and eats it. However, it can't digest an oxidize LDL molecule and becomes something called a Foam Cell (why? cause it looks like foam).

When these Foam Cells build up in the lining of your arteries you have trouble - this is called atherosclerosis. Basically, they build up, further and further, over time. Eventually it will prevent the passage of blood through the artery, causing damage (stroke, heart attack, thrombosis, etc.)

So, bottom line: Cholesterol is necessary for you to live, but dangerous in high levels. We use it to fuel normal processes in our bodies, but it can also 'clog' our arteries. I hope that was understandable.

Answer 3

Cholesterol is a waxy material found in our cells that's used to make hormones, vitamin D, and other substances in the body.

HDL (High Density Lipoprotein) is a cholesterol that is good for you, it is lowered by smoking the most (list you favorites for what else)

LDL is low densiry lipoprotein and this is the stuff everyone hears about.

If HDL is too low <60 then there is a good chance for heart disease, stroke, etc. Thus why smoking is such a killer besides lung cancer. With a low HDL (AND SMOKING), the blood vessel walls weaken making it much easier to have clots form thus leading to stroke and heart attacks. (Good early warning sign is SIGNS of penile dysfunction in 30 year and older males)

So if you are old enough to remember that when fathers used to tell their boys dont smoke or you wont keep a "stiffy" thats where that comes from.

With LDL its just plain ol' cork the arteries. LDL>100 is bad news

People confuse triglycerides with cholesterol, they do however go hand in hand. If you do have high triglycerides (a type of body fat that floats around in the blood) it usually is a marker for excess cholesterol but it also a marker for increased chance of diabetes.

P.S. FYI quitting smoking wont repair the arteries but it will raise the HDL levels that will help prevent things from happening.

so now you know, quit smoking!

Answer 4

it collects on the veins its know to be bad for your heart
Typically the body makes all the cholesterol it needs, so people don't need to consume it. Saturated fatty acids are the main culprit in raising blood cholesterol, which increases your risk of heart disease. Trans fats also raise blood cholesterol. But dietary cholesterol also plays a part. The average American man consumes about 337 milligrams of cholesterol a day; the average woman, 217 milligrams.

Answer 5

No it does NOT clog arteries!!

Oxidized cholesterol will clog your arteries. Oxidized cholesterol is found in powdered milk and powdered eggs. Powdered milk is in 1% and 2% milk. So acturally drinking low fat milk is bad for your heart. Full fat whole milk that is not ultra pasterized or homogenized from healthy grass fed animals not from the confinement dairy farms

Answer 6

cholesterol affects the heart. cholesterol gets hardens the arteries and the blood circulation slows down:

Answer 7

I would think that a high cholesterol level makes you feel like crap and thusly would make you feel less excitable. It also affects blood flow, so the older the man gets, the more it may disrupt blood flow to the right places.

Answer 8

It clogs the arteries and can cause a stroke or heart attack.
