“That’s because high cholesterol can be caused by different things. It can be caused by an unhealthy lifestyle, but it can be genetic too.”
The Mayo Clinic explains high cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries.
It says: “These deposits (plaques) can reduce blood flow through your arteries, which can cause complications.” These may include chest pain, heart attack, and stroke.
The NHS says: “This is because cholesterol can build up in the artery wall, restricting the blood flow to your heart, brain and the rest of your body. It also increases the risk of a blood clot developing somewhere in your body.”
