Does low potassium cause high blood pressure?

Patient's question:

Colleague's mother recently had a thorough check-up and found she has low potassium. Hello doctor, does low potassium cause high blood pressure?

Doctor's answer:

Hello, how does low potassium lead to high blood pressure? This is mainly because about 50% of patients with malignant hypertension may experience recurrent hypokalemic metabolic alkalosis in hypertension. They may also have hyponatremia. It is recommended to consume appropriate amounts of high-potassium foods in daily diet, such as bananas which are rich in potassium. In diet, it is important to follow a high-potassium and low-sodium diet. Avoid eating animal organs, fatty meats, fish roe, egg yolks, etc.
