Repeated elevation of blood potassium can be treated by dialysis, stopping potassium intake, lowering blood potassium concentration, reducing potassium-containing food intake, and treatment of underlying diseases. 1. Elevated blood potassium may be caused by a decrease in renal potassium excretion, such as when the patient suffers from renal insufficiency or acute renal failure, which can be treated by dialysis therapy to expel the excess potassium from the body. 2. If the blood potassium is repeatedly elevated due to excessive intake of potassium-containing food, the patient should pay attention to not consuming potassium-containing food in the diet. For example, fruits, salted vegetables and so on. In addition, you should stop consuming all potassium-containing medicines or solutions to avoid further elevation of blood potassium. 3. For the treatment of severe hyperkalemia, sodium lactate, sodium bicarbonate, calcium, and hypertonic saline can also be used to shift serum potassium into the cells if necessary. Diuretics, such as furosemide, can also be used to remove excess blood potassium from the body through urination. In addition, repeated elevation of blood potassium needs to be investigated for diseases causing elevation of blood potassium, such as severe hemolysis, extensive burns, and renal diseases, etc., and the cause of the disease should be identified and then treated according to the cause of the disease. Repeatedly elevated blood potassium is recommended to go to the hospital in a timely manner, and medication should be used in accordance with the doctor’s instructions.
