Ateroskleroz, also known as atherosclerosis, is a condition where the arteries become narrowed and hardened due to the buildup of plaque. This plaque is made up of fat, cholesterol, and other substances found in the blood. Over time, this buildup can restrict blood flow, leading to serious health issues such as heart attacks and strokes. The process of ateroskleroz often begins in childhood and progresses with age. Risk factors include high blood pressure, high cholesterol, smoking, and diabetes. Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help reduce the risk of developing ateroskleroz.
