Every organ in the body needs oxygen to work actively. The oxygen is supplied when the blood passes through each part of the body by means of arteries. Factors like smoking, alcohol, stress, over salt in the diet may cause the artery wall to get narrower. As a result, the blood cannot pass through the vital organ, as a result, the organs in the body cannot work properly. So it may result in the heart failure, coronary artery disease, chronic kidney disease, vision loss, etc. In most of the cases of the hypertension, there won’t be any symptoms or alert in the body.
