"Too much cholesterol in the blood can lead to build up of fatty plaques on the walls of blood vessels known as atheroma," warned Doctor Luke Pratsides, Lead GP at digital healthcare company Numan.
Accord to Doctor Pratsides, atheroma can completely or partially block blood vessels.
However, "with time these atheroma and the blood blood vessel walls harden in a process known as atherosclerosis".
He said: "In the coronary arteries, blood vessels that supply the heart, atherosclerosis can mean the heart muscle does not get enough blood supply and the oxygen and nutrients it needs from the blood.".
According to Doctor Pratsides, this is known as ischaemia and can cause chest pain which initially comes on after exertion, known as stable angina.
"In the brain, atherosclerosis in the small vessels can lead to memory loss and progressive cognitive degeneration known as vascular dementia," warned Doctor Pratsides
He continued: "In larger vessels it can lead to stroke-like symptoms that resolve after a short time known as transient ischaemic attacks or TIAs."
