High blood pressure, or hypertension, can have a significant impact on the arteries. When blood pressure is consistently high, the walls of the arteries can become thickened and stiff. This can lead to a condition known as atherosclerosis, where plaque builds up in the arteries, narrowing them and making it harder for blood to flow. Over time, this can increase the risk of serious health issues, including heart attacks and strokes. It's important to monitor blood pressure regularly and work with your healthcare provider to keep it within a healthy range. Lifestyle changes, such as a balanced diet and regular exercise, can help manage blood pressure effectively.
