People with high blood pressure often have high cholesterol. But that doesn’t mean it causes high blood pressure. It is possible that similar factors cause both high blood pressure and high cholesterol.
Having both risk factors raises your risk of heart attack and stroke. Some doctors think that high cholesterol may make your arteries stiffer. This could make you more prone to have high blood pressure. High cholesterol can also damage the vessels in the kidneys. When your kidneys are damaged, you are more likely to get high blood pressure.
