If hypertension is combined with potassium reduction, it is necessary to clarify whether it is primary aldosteronism and adrenal function abnormality that causes potassium reduction, and potassium supplementation should be based on the specific etiology of the disease. If the patient is primary hypertension, potassium supplementation is mainly applied in the short term, such as potassium chloride delayed-release tablets for potassium supplementation. After the blood potassium is normalized, more potassium-rich fruits and vegetables, such as bananas, oranges, grapefruit, or dark-colored vegetables can be consumed, and low-sodium salt can be chosen, which also contains a certain amount of potassium, and at the same time will limit the intake of sodium, which is very suitable for people with hypertension. It is very suitable for people with high blood pressure. In the case of secondary hypertension, such as primary aldosteronism, potassium supplementation in this case is mainly aimed at preventing the loss of potassium, and the intake of drugs such as spironolactone should be used to control the treatment.
