Hello, my name is Dr. Susan Jewell and on behalf of Expert Village today I'm going to
talk to you about the subject of lowering cholesterol. Now in this clip we can talk
about how plaques are formed. Plaques are like clots of cholesterol all stuck together
and sticking on the vessel walls. So here's a diagram that I've drawn of a blood vessel.
Here's a blood vessel and we've just cut across the blood vessel itself. So we are looking
at the inside of the blood vessel. Now normally a healthy blood vessel doesn't have any deposits
on side of the wall. You can see here so that blood can flow very freely through the blood
vessel without any impedance or any obstruction. When people have terrible diets. When they
are eating high, fatty diets or certain drugs can also cause it or certain diseases and
medication will cause certain deposits to flow through the blood vessels. Especially
on people who are on terrible diets. These fats and deposits then stop to deposit on
the edge of the vessel walls as it moves along the vessel down. So it starts building up
over years. So as you keep or continue to eat a terrible diet or if you have certain
medications that causes this secretion collection of fatty deposits. Eventually over time you
are going to form a plaque and here you can see that we have these red bumps or the plaques
that are formed inside the vessel itself and when that happens over time you are going
to get obstruction of the flow of blood through the capillary. These plaques will obstruct
the flow and eventually the plaques will build up to a point where it's going to keep depositing
and then you are going to have total occlusion of the vessel we called obstruction of the
vessel. So then you're going to stop any blood flowing through the vessel itself and that
if it happens in a major artery you are going to get cardiovascular problems. You're going
to get strokes and heart attacks. So that is why as medical doctors and also to inform
the public that you should always reduce the type of food that has high, fatty content
and also to exercise and eat healthy to prevent the risk of getting plaque formation and to
get cardiovascular problems.
