was wonderin if swale or someone in the med field can answer this for me
i understand what they are and how exercise and good cholesterole
helps to combat the build-up of them
my question is . once they are deposited are they there forever
or will clean diet and exercise clean up the arteries ?
I don't claim to be an expert on atheroschlerosis but I know my fair share about it. As far as I can tell, once plaque is deposited, there is no way to decrease it. In fact, the deposition only becomes worse as you age. And some people will experience faster accumulation of plaque than others. But unless you surgically remove the plaque formation, it will eventually become worse and not better.
Some causes of atheroschlerosis are increased blood lipids(fats), increased cholesterol and triglycerides, obesity, high blood pressure, stress, smoking, diabetes, aging and of course genetics.
Plaque buildup forms within the muscular portion of the arterial wall when the artery is damaged internally. Tiny little micro tears occur from many factors including smoking, stress, high blood pressure, age and genetics. These small tears need to be filled in to prevent further damage to the artery. So your body fills in those tears with cholesterol and lipids. And the vehicle to cary the lipids and cholesterol to the tear is the triglycerides. So you might have high triglycerides and cholesterol but if there's few arterial tears to fill in, there's not much work for them to do.
Now, abnormal or increased plaque deposition happens because something is going wrong with this usually normal "filling" process. For whatever reason, the triglycerides carry all the cholesterol and lipids to the arterial tears and begin to fill the gaps. Only something is stuck in high gear. The gaps get filled but the signal has not been received properly to turn off this normal response. So the gaps get more and more material deposited on top of them. That's when you get a "bulging" that pushes inward tward the inside of the artery decreasing normal arterial blood flow(blockage). Diabetes and poor genetics cause this normal filling process to deposit layer after abnormal layer of plaque at the arterial tear site.
You can somewhat prevent this abnormal filling process from happening. You can't alter your genetics just yet so that's not an option. But you can keep your cholesterol and triglycerides within a normal range. And you can controll you diabetes. Eliminate smoking and decrease the amount of secondhand smoke you breathe. Controll your blood pressure. And get a grip on obesity.
Hope this helps.
