Arteriosclerosis is a condition characterized by the thickening and hardening of the walls of the arteries. This process can restrict blood flow to organs and tissues, leading to various cardiovascular diseases. It often results from the accumulation of fatty deposits, cholesterol, and other substances in the arterial walls. Risk factors include high blood pressure, smoking, diabetes, and high cholesterol. Managing lifestyle factors and seeking medical treatment can help reduce the risk of arteriosclerosis and its complications.
