How can hyperkalemia (high blood potassium levels) be prevented?
High blood potassium levels can be prevented if disorders are treated that might cause hyperkalemia. If one of these disorders exists, the blood potassium levels must be watched closely by a nurse or doctor. Potassium supplements should not be taken if a person’s kidneys are not working properly. People with hyperkalemia should follow a diet low in potassium. A dietician can be consulted to help plan low-potassium meals.
