Arteriosclerosis is a condition characterized by the thickening and hardening of the walls of arteries. This process can lead to reduced blood flow and increased blood pressure, making it harder for the heart to pump blood effectively. Over time, it can contribute to serious health issues, including heart disease and stroke. There are different types of arteriosclerosis, with atherosclerosis being the most common. Atherosclerosis involves the buildup of fatty deposits, or plaques, in the arteries, which can further narrow the blood vessels. Lifestyle factors such as poor diet, lack of exercise, and smoking can increase the risk of developing this condition.
