Final answer:
Hypokalemia is a condition characterized by low levels of potassium in the blood and can be a cause of resistant hypertension. Addressing the underlying hypokalemia through potassium supplementation can help improve and prevent hypertension.
Step-by-step explanation:
Hypokalemia is a condition characterized by low levels of potassium in the blood. It can be a cause of resistant hypertension, particularly in middle-aged patients. The low levels of potassium can lead to an imbalance in electrolytes, which affects blood pressure regulation. Additionally, potassium has been shown to have beneficial effects on blood pressure by reducing platelet aggregation, vascular resistance, and inflammation. Addressing the underlying hypokalemia through potassium supplementation can help improve and prevent hypertension.
