why does blood get thinner whenyou get older?

Answer 1

the blood doesnt get thinner. the arteries and veins lose their compliance as they age which means they arent able to expand, dilate, and constrict as they used to if the pressure increases. Since they cant expand as well, the resistance of blood increases which increases blood pressure.

Answer 2

Your blood doesn't really get thinner as you get older. You can take things to make it thinner. That is why doctors prescribe blood thinners to people so their blood doesn't clot and cause strokes and heart attacks if you are at a risk for those types of diseases. Aspirin is a blood thinner.

Some supplements will cause your blood to thin. That is why if you are to have surgery they ask you to stop taking them about 2 weeks prior. They want your blood to clot if they are going to be performing surgery.

Our skin can "thin" as we get older. It becomes less elastic and older skin becomes more fragile. Our skin becomes drier as we get older because we lose the oil in it. We get more wrinkles.

Aging conjures up many images: wrinkles appear; skin loses its freshness and elasticity; bones thin down and become brittle; the normal fat-muscle ratio of 1 to 3 goes down due to muscle wasting; diminished eyesight and hearing, stiffening of joints and decreased range of motion, etc..

We have to watch our health and diet that is for sure as they play a part on how we feel as we get older.

The body keeps renewing itself continuously. Bones keep taking fresh calcium and keep rebuilding themselves. The stomach lining renews itself every five days (if it didn't change that often we would have to contend with big holes in our stomach). The skin is replaced every month, the liver every six weeks, and the skeleton every three months. In one year from today, 98 percent of the atoms in our body will be exchanged for new ones. In one year, excepting the two percent, we become new bodies. How do we ever get old?

After 30 years of age, all the changes in body amount to one percent each year. In other words, the decay is one percent for each year of life. By the time one reaches eightieth birthday, there is 50% loss of what one had at age thirty. But "long-lifers" know what to do to slow down that process, otherwise, the lady who turned 120 this year, would have had only 10% of her muscles and skeleton left. The one percent decay can perhaps be reduced by one's expectations from oneself, the intention to stay young and healthy, and to be creative and adaptive.

Answer 3

It doesn't. Often just the opposite happens, since many have a cholesterol problem... which causes blood the clump... This is why aspirin is used to keep blood thin,

Answer 4

It doesn't. "Thin blood" is a non-medical term that can have several meanings, and in an Alice-in-Wonderland way means exactly whatever the speaker means for it to, and nothing else.
