What happens if you have high cholesterol?
How does cholesterol clog up your arteries?
Excess cholesterol can be laid down in the walls of your arteries. Fatty areas known as plaques can form, and these become harder with time, making the arteries stiffer and narrower. This process is called atherosclerosis.When the arteries become narrower, it’s harder for blood to flow through them. This puts a strain on your heart because it has to work harder to pump blood around your body. Eventually, the heart can become weak and can’t work as well as it should.
