Which of the following can result from untreated hypertension?

Untreated hypertension, or high blood pressure, is a significant health concern that can lead to various serious complications. One of the most critical consequences of untreated hypertension is an increased risk of cardiovascular disease. This risk stems from the damage that high blood pressure does to the arterial walls, promoting atherosclerosis, or the buildup of plaque within the arteries. Over time, this can lead to conditions such as coronary artery disease, heart failure, stroke, and other cardiovascular problems.

Moreover, hypertension forces the heart to work harder than normal, which can lead to left ventricular hypertrophy and an increased likelihood of heart failure. The systemic effects of hypertension can also contribute to damage in other organs, such as the kidneys and eyes, further increasing the risk of serious health issues.

In contrast to this, the other options do not arise from untreated hypertension. Decreased joint flexibility, increased metabolic rate, and improved muscle function are not direct outcomes of being hypertensive and are not typically recognized as complications associated with high blood pressure. Understanding the link between untreated hypertension and cardiovascular disease is essential for recognizing the importance of managing blood pressure effectively.
