Potassium supplement can be divided into medicine supplement and food supplement. Potassium chloride is usually the first choice of drug supplement, which is mainly suitable for patients who take diuretics for antihypertensive treatment and should be taken under the guidance of a doctor. The correct way to supplement potassium is not that the more potassium, the better. Excessive potassium is also harmful to human body. Hyperkalemia may cause arrhythmia and lead to death.

Therefore, patients who use drugs to supplement potassium should draw blood to check their blood potassium at any time, and it is appropriate to supplement it when hypokalemia is diagnosed. However, potassium supplementation has no contraindications and is suitable for all patients with hypertension, including patients with mild hypertension or those who have not taken antihypertensive drugs.

There are many foods rich in potassium, mainly seafood such as lean meat, beef and fish. Vegetables and fruits, such as Chinese cabbage, rape, cucumber, tomato, potato, orange, banana, peach, raisin, etc., can be reasonably prepared according to the needs of patients, scientifically cooked, and play an auxiliary role in the treatment process.

In addition, some people worry that eating high-protein foods such as lean meat and fish may be unfavorable to patients with hypertension, which is unnecessary. The results show that low-protein diet is more harmful to hypertensive patients than high-fat diet (high-fat diet is the main cause of hyperthyroidism). Therefore, patients with hypertension should ensure proper supply of protein.

Of course, when eating lean meat, fish and other high-protein foods, it is necessary to ensure that the intake of protein accounts for about 15% of the total calories. It is also important for hypertensive patients to control total calories and maintain standard weight.

Potassium is an important substance necessary for maintaining human metabolism, intracellular pressure balance, nerve conduction and muscle contraction. Potassium deficiency can cause dysfunction of many systems in human body, which can be life-threatening in severe cases. Recently, scientists also found that potassium can protect blood vessels and prevent arterial wall from being damaged. Potassium deficiency can cause arterial wall thickening in patients with hypertension, thus increasing the probability of stroke in patients with hypertension.

Patients with hypertension should check their renal function before potassium supplementation to avoid potassium excretion limitation due to renal insufficiency, which will lead to hyperkalemia. In addition, patients with hypertension need a process to supplement potassium, and they should not be rushed, otherwise it will do harm to the body.
