Which of the following is a potential complication of untreated hypertension?

Untreated hypertension can lead to several serious health complications, and one of the most significant is the risk of stroke. High blood pressure puts excess strain on the blood vessels, leading to damage over time. This damage can result in the formation of blood clots or the rupture of blood vessels in the brain, both of which can cause a stroke. The relationship between hypertension and stroke is well-documented, with individuals suffering from chronic high blood pressure having a considerably higher risk of experiencing a stroke compared to those who maintain normal blood pressure levels. Therefore, recognizing and managing hypertension is crucial in preventing strokes and preserving neurological function.

In contrast, while other options may correlate with different health conditions, they do not directly reflect the consequences of untreated hypertension. Hypoglycemia is related to insulin and glucose management, diarrhea may have various causes including infections or dietary issues, and acid reflux is connected to digestive health rather than cardiovascular conditions. Thus, the link between hypertension and stroke is clear and highlights the importance of monitoring and controlling blood pressure.
