what causes hyperkalemia

Common Causes

Possible causes of hyperkalemia may include: Chronic kidney disease: A lower kidney capacity means that the kidneys may not be able to filter potassium out of the body adequately. Uncontrolled or untreated diabetes: As a decrease in kidney function is a possible complication of diabetes, poorly managing the condition may result in hyperkalemia.

Related Conditions

• Even mild hyperkalemia, if not treated, can become severe and be fatal. It can lead to a dangerous disorder called ventricular fibrillation. This causes the lower part of the heart to flutter, causing rapid pumping of blood. This could lead to a heart attack and can be fatal.

What condition may result in hyperkalemia?

With hyperkalemia, your body has too much potassium for your kidneys to remove. As a result, potassium builds up in your blood. In addition to conditions like kidney disease, these factors also contribute to hyperkalemia: A high-potassium diet, which can result from potassium supplements and salt substitutes.

What are the risks associated with hyperkalemia?

Up until recently, FDA-approved therapies for the management of hyperkalemia (i.e., sodium polystyrene sulfonate) had remained unchanged for over 50 years. Other treatment options for hyperkalemia include IV calcium, insulin, sodium bicarbonate, albuterol, and diuretics.

What causes high potassium levels in the body?

Kidney Disease. Hyperkalemia can happen if your kidneys do not work well. It is the job of the kidneys to balance the amount of potassium taken in with the amount lost in urine. Potassium is taken in through the foods you eat and the liquids you drink. It is filtered by the kidneys and lost through the urine. In the early stages of kidney disease , the kidneys can often make up for high potassium. But as kidney function gets worse, they may not be able to remove enough potassium from your body. Advanced kidney disease is a common cause of hyperkalemia.

Other (less common) causes include: 1 Taking extra potassium, such as salt substitutes or supplements. 2 A disorder called “Addisons disease”, which can occur if your body does not make enough of certain hormones. Hormones are chemicals produced by different glands and organs, including the kidneys, to trigger certain responses in your body. 3 Burns or other severe injuries. This occurs because your body, in response to severe burns or injuries releases extra potassium in your blood. 4 Poorly controlled diabetes. 5 When diabetes is not controlled, it has a direct effect on your kidneys which are responsible for balancing potassium in your body.

Hyperkalemia (High Potassium) People with hyperkalemia have high potassium levels in their blood. Signs like fatigue and muscle weakness are easy to dismiss. A low-potassium diet and medication changes often bring potassium numbers to a safe level. An extremely high potassium level can cause a heart attack and requires immediate medical care.

What is the normal potassium level?

A typical potassium level for an adult falls between 3.5 and 5.0 millimoles per liter (mmol/L). Hyperkalemia occurs when levels go above 5.5 mmol/L. A reading above 6.5 mmol/L can cause heart problems that require immediate medical attention.

Potassium is an essential nutrient found in foods. This nutrient helps your nerves and muscles function. But too much potassium in your blood can damage your heart and cause a heart attack. You can’t always tell when your potassium levels are high.

How do you know if you have high potassium?

Because most people don’t have symptoms, you might not know you have high potassium until you get a routine blood test. A serum potassium test measures potassium levels in blood. Your healthcare provider may also order an electrocardiogram (EKG). This test shows changes in heart rhythm caused by hyperkalemia.

How to get rid of high potassium in urine?

Options include: Diuretics: Also called water pills, these drugs make you pee more often. Your body gets rid of potassium mainly in urine. Intravenous (IV) therapy: Extremely high potassium levels need immediate treatment. You’ll receive an IV infusion of calcium to protect your heart.

How to manage hyperkalemia?

The management of hyperkalemia is done by an interprofessional team because of its potential to induce cardiac arrest and severe weakness. Once hyperkalemia is diagnosed, the primary condition must be treated.  Patients with hyperkalemia need cardiac monitoring and nurses should be familiar with ECG features of hyperkalemia, which are often the first to appear. The pharmacist has to ensure that all nephrotoxic medications and agents that raise potassium are discontinued and discuss their findings with the clinical team. Nursing will perform monitoring and follow-up, watching for signs of worsening hyperkalemia and alerting the clinical staff immediately for corrective action.

What is the first test for hyperkalemia?

The first test that should be ordered in a patient with suspected hyperkalemia is an ECG since the most lethal complication of hyperkalemia is cardiac condition abnormalities which can lead to dysrhythmias and death. [5][6][7][8]

What causes potassium to be elevated?

Metabolic acidosis may cause intracellular potassium to shift into the extracellular space without red cell injury.   Metabolic acidosis is most frequently caused by decreased, effective, circulating, arterial blood volume. Sepsis or dehydration may lead to hypotension and decreased tissue perfusion leading to metabolic acidosis with subsequent potassium elevation. Insulin deficiency and diabetic ketoacidosis may cause dramatic extracellular shifts causing measured serum potassium to be elevated in the setting of whole-body potassium depletion. Certain medications, such as succinylcholine may cause severe, acute potassium elevations in patients with up-regulation of receptors, particularly in the setting of subacute neuromuscular disease. Tumor lysis syndrome, particularly in patients receiving chemotherapy for hematogenous malignancy, may cause acute hyperkalemia due to massive cancer cell death. Hyperkalemic periodic paralysis is a rare, autosomal dominant condition that causes potassium to shift into the extracellular space due to impaired sodium channel function in skeletal muscle.

What foods cause high potassium levels?

Foods with very high potassium content include dried fruits, seaweed, nuts, molasses, avocados, and Lima beans. Many vegetables that are also high in potassium include spinach, potatoes, tomatoes, broccoli, beets, carrots, and squash. High-potassium-containing fruits include kiwis, mangoes, oranges, bananas, and cantaloupe. Red meats are also rich in potassium. While generally safe to consume even in large quantities by patients with normal potassium homeostasis, these foods should be avoided in patients with severe renal disease or other underlying conditions or medications that predispose them to hyperkalemia. Intravenous intake through high potassium-containing fluids, particularly total parenteral nutrition, medications with high potassium content, and massive blood transfusions can significantly elevate serum potassium levels.

What is the normal level of potassium?

Hyperkalemia is defined as a serum or plasma potassium level above the upper limits of normal, usually greater than 5.0 mEq/L to 5.5 mEq/L. While mild hyperkalemia is usually asymptomatic, high levels of potassium may cause life-threatening cardiac arrhythmias, muscle weakness, or paralysis. Symptoms usually develop at levels higher levels, 6.5 mEq/L to 7 mEq/L, but the rate of change is more important than the numerical value. This activity reviews the causes, pathophysiology, and presentation of hyperkalemia and highlights the role of the interprofessional team in its management.

Is hyperkalemia a false elevation?

Pseudohyperkalemia is quite common and represents a false elevation in measured potassium due to specimen collection, handling, or other causes. Hyperkalemia should always be confirmed before aggressive treatment in cases where the serum potassium is elevated without explanation. True hyperkalemia may be caused by increased potassium intake, transcellular movement of intracellular potassium into the extracellular space, and decreased renal excretion. The urgency of therapy depends on symptoms, serum levels, and explanation for hyperkalemia. [1][2][3][4]

Is hyperkalemia rare in children?

Diabetes, malignancy, extremes of age, and acidosis are other important causes in inpatients. Hyperkalemia is rare in children but may occur in up to 50% of premature infants. Hyperkalemia is more commonly reported in men than women perhaps due to increased muscle mass and higher rates of rhabdomyolysis and increased prevalence of neuromuscular disease.
