High potassium, or hyperkalemia, can lead to serious side effects if left untreated. The condition can be caused by kidney disease, poorly controlled diabetes, certain medications, and herbal supplements. Treatment for hyperkalemia in a hospital setting involves addressing the underlying cause and reducing potassium levels through medication, dialysis, or lifestyle changes. The chosen treatment method depends on the severity and cause of the condition.
| Characteristics | Values |

| Treatment for chronic hyperkalemia | Can be managed outside of the hospital, changes to diet and medication, diuretics, potassium binders |
| Drugs to avoid | Nonsteroidal anti-inflammatory drugs (NSAIDs), herbal supplements, potassium supplements |
| Drugs that can help | Patiromer, sodium polystyrene sulphonate, sodium zirconium cyclosilicate, diuretics, insulin, albuterol, calcium |

What You'll Learn
Adjusting diet and medication
Dietary Adjustments:
- Lowering Potassium Intake: Patients are advised to reduce their consumption of potassium-rich foods. This is crucial, especially for individuals with kidney disease, as high potassium intake can exacerbate the condition.
- Monitoring Food Choices: Patients should be vigilant about the potassium content in their diet. This may involve consulting with a dietician or nutritionist to develop a low-potassium meal plan.
- Avoiding Herbal Remedies and Supplements: Herbal remedies and supplements are often discouraged for individuals with hyperkalemia, as they may contain ingredients that further increase potassium levels.
Medication Adjustments:
- Diuretics: Also known as "water pills," diuretics are a common treatment option. They help flush out excess potassium by increasing urine production and are particularly effective in mild cases.
- Potassium Binders: These medications, including patiromer (Veltassa) and sodium zirconium cyclosilicate (Lokelma), attach to potassium in the intestines, allowing it to be excreted through stool. They are prescribed when dietary changes and other treatments are insufficient.
- Adjusting Current Medications: In some cases, high potassium levels may be caused by certain medications. Doctors may adjust, lower doses, or temporarily stop these medications to alleviate the issue. It is crucial not to discontinue any medication without medical advice.
- Intravenous Treatments: In emergency cases, intravenous (IV) treatments may be administered. These include calcium, insulin, glucose, and sodium bicarbonate, which work to quickly shift potassium from the blood into the body's cells.
It is important to note that the specific treatment plan will depend on the patient's condition, the severity of hyperkalemia, and the underlying causes. Doctors will carefully assess each case to determine the most appropriate course of action, which may include a combination of dietary adjustments and medication interventions.

Intravenous calcium
It is important to note that intravenous calcium should be used in conjunction with other therapies that help lower serum potassium levels, as it does not directly reduce potassium levels. This could include the use of diuretics, insulin, or potassium binders.

Dialysis
Potassium binders, such as sodium or calcium polystyrene sulphonate, are another treatment option for hyperkalemia. These binders work by exchanging potassium for sodium or calcium in the gastrointestinal tract, thereby reducing potassium absorption. However, it is important to note that oral potassium supplements did not show a survival benefit in a study of haemodialysis patients.
Mathematical modelling of potassium profiling has been proposed to individualize treatment for patients on haemodialysis. This approach involves in-line monitoring of potassium levels using optical ion-selective microsensors. Additionally, maintaining a constant dialysate-serum potassium gradient is important, as a higher gradient may contribute to an arrhythmogenic effect and impact blood pressure during and after dialysis.
Overall, dialysis plays a crucial role in managing hyperkalemia, especially in patients with kidney disease or failure. It is often used in conjunction with other treatments and dietary modifications to effectively lower potassium levels and prevent potential life-threatening complications associated with high potassium levels.

Potassium binders
There are several types of potassium binders available, including patiromer (Veltassa), sodium polystyrene sulfonate (Kayexalate), and sodium zirconium cyclosilicate (Lokelma). Patiromer and sodium zirconium cyclosilicate may be particularly effective for individuals with heart disease or diabetes. Calcium polystyrene sulfonate is another type of potassium binder.
While potassium binders can be effective in lowering potassium levels, they may also cause side effects, primarily related to digestive issues. These can include abdominal pain, constipation, gas, indigestion, nausea, and vomiting. Some newer potassium binders may also lower calcium and magnesium levels. It is important to discuss any medications or supplements with a healthcare provider before taking potassium binders to ensure safe and effective use.
In addition to potassium binders, other treatments for hyperkalemia include diuretics (water pills) and, in severe cases, dialysis. Adjustments to diet and medications may also be recommended to help manage potassium levels.

Monitoring and treatment of underlying conditions
High potassium levels, or hyperkalemia, can be caused by a variety of underlying conditions and lifestyle factors. It is important to identify and address these underlying issues to effectively manage potassium levels. Here are some key considerations:
- Kidney function: The kidneys play a crucial role in maintaining potassium balance. Chronic kidney disease is the most common cause of hyperkalemia. If the kidneys are not functioning properly, they may not be able to remove enough potassium from the body, leading to a buildup of potassium in the blood. It is important to monitor kidney function through blood tests and treat any underlying kidney disease.
- Medications: Certain medications can interfere with kidney function or directly impact potassium levels. These include drugs for heart health, such as ACE inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen. It is important to review all medications with a doctor and make adjustments if necessary.
- Diet: A diet high in potassium can contribute to hyperkalemia, especially in individuals with kidney disease. Reducing potassium intake by adopting a low-potassium diet is an important part of managing potassium levels.
- Herbal supplements: Herbal remedies and supplements should be used with caution as they may contain ingredients that increase potassium levels. It is important to consult a doctor before taking any supplements to ensure they do not affect potassium levels.
- Other medical conditions: Conditions such as diabetes, Addison's disease, and heart failure can impact potassium levels. Managing these underlying conditions is an important part of treating hyperkalemia.
- Lifestyle factors: Lifestyle factors, such as a low-sodium diet, can also contribute to high potassium levels. Addressing these factors may help in managing potassium levels.
By addressing these underlying conditions and making necessary lifestyle and dietary changes, individuals with hyperkalemia can effectively manage their potassium levels and reduce the risk of associated complications.

Frequently asked questions
High potassium, or an excess of potassium in the blood, is called hyperkalemia.
Symptoms of hyperkalemia include severe muscle weakness, paralysis, heart rhythm problems, chest pain, heart palpitations, nausea, and vomiting.
Treatment options for hyperkalemia include diuretics (water pills), dialysis, and medications such as patiromer (Veltassa), sodium polystyrene sulfonate (Kayexalate), and sodium zirconium cyclosilicate (Lokelma). In less severe cases, dietary changes and adjustments to medications can help lower potassium levels.
Hyperkalemia is often caused by kidney disease, but it can also be caused by certain medications, Addison's disease, uncontrolled diabetes, or a serious injury or severe burn.
To prevent hyperkalemia, it is important to maintain a healthy balance of potassium through diet and medication. Speak to your doctor about any medications or supplements you are taking, and be cautious of herbal remedies or supplements, as these may contain hidden sources of potassium.
