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.
Why does potassium rise?
This can cause your potassium levels to rise. Other (less common) causes include: Taking extra potassium , such as salt substitutes or supplements. A disorder called “Addisons disease”, which can occur if your body does not make enough of certain hormones.

What is hyperkalemia in 2021?
Updated on June 28, 2021. Hyperkalemia occurs when you have too much potassium in your blood. Because hyperkalemia is a sign that something else is going on in your body, treatment depends on what's causing it and whether the level of potassium in your blood is judged to be an emergency or not.
How to reduce potassium levels in blood?
If your hyperkalemia isn't severe and you're able to work on gradually lowering the amount of potassium in your blood, your healthcare provider will start by having you reduce the amount of potassium in your diet. If you have high blood pressure or hypervolemia, you may also be given diuretics to help keep your levels low. For people who have hyperkalemia from taking RAAS inhibitors, a diet low in potassium and regular diuretic therapy can help keep hyperkalemia at bay.

Why do you need to keep dialysis?
You may need to keep having dialysis to prevent hyperkalemia.
How to treat hyperkalemia?
Treatment of hyperkalemia can be divided into acute and long-term therapy. The approach to treatment differs in patients with acute renal failure and CKD. In patients with chronic renal disease, a new steady state develops in which potassium excretion is stimulated at a different, higher, extracellular potassium level, so that it again matches the intake. When this new steady state is reached, plasma potassium remains stable unless a new event occurs that shatters the balance (7). A recent retrospective study of over 245,000 patients examined the frequency of hyperkalemia and the impact of renal dysfunction (8). For each stage of renal function (normal to Stage 5 CKD) as the level of hyperkalemia increased, the odds of death increased. However, for a given level of hyperkalemia, there was an inverse relationship between the stage of CKD and odds of 1-day mortality after a hyperkalemic event (8).
What is pseudohyperkalemia?
Pseudohyperkalemia (fictitious hyperkalemia) Pseudohyperkalemia commonly arises from shifts of potassium from blood cells to blood plasma by mechanical trauma during venipuncture or during the clotting process in vitro. These effects are further enhanced when there is marked leukocytosis or thrombocytosis.
What is the most reliable method to remove potassium from the body?
Hemodialysis remains the most reliable method to remove potassium from the body and should be used in cases refractory to medical treatment. Prompt detection and proper treatment are crucial in preventing lethal outcomes. Keywords: hyperkalemia, review, treatment, potassium, hyperkalemic.
How does potassium affect the heart?
Any imbalance of this concentration gradient affects the ability of the heart to maintain a normal rhythm. The concentration gradient is maintained by the sodium potassium ATPase pumps located on the cellular membrane that actively pump sodium outside and potassium inside the cell. When the potassium level increases in the extracellular space, the potassium concentration gradient across the cellular wall decreases; and this decreases the resting membrane potential. The change in resting membrane potential caused by hyperkalemia is the principle pathophysiologic mechanism behind most of its symptoms. The decrease in the resting membrane potential decreases the number of sodium channels activated that in turn decrease the magnitude of inward sodium current. This causes a prolonged conduction of the impulse with prolonged depolarization (3).
What are the distribution abnormalities of potassium?
Distribution abnormalities of potassium are seen during metabolic acidosis, insulin deficiency, aldosterone deficiency, adrenergic antagonists, and tissue damage. During metabolic acidosis, there is a significant extracellular shift of intracellular potassium in exchange for protons leading to hyperkalemia.
How long does potassium stay in the blood?
Serum potassium level starts trending down within 10–20 min of insulin and glucose administration with maximal action in 60 min: The effect lasts for 2–6 hours.
Can a medication cause hyperkalemia?
In addition to interfering with the renin-aldosterone axis, medications can cause hyperkalemia by other mechanisms. Potassium-sparing diuretics (amiloride and triamterene), trimethoprim, and pentamidine all block sodium reabsorption in the distal nephron, reducing the luminal voltage gradient, and decreasing potassium excretion rates. Spironolactone blocks aldosterone receptors, and cyclosporine causes hyperkalemia by enhancing chloride reabsorption.
What to do if you have hyperkalemia?
The first thing your doctor will likely do is retest your potassium level to see if the first test was accurate. Blood tests will also check your kidney function. Chronic kidney disease is the most common cause of hyperkalemia.
What is the best way to lower potassium levels?
You’ll need urgent treatments to quickly lower your potassium level. These may include intravenous (IV) calcium, insulin and glucose, and albuterol. These shift potassium out of your blood and into your body's cells.
What to do if your kidneys aren't removing enough acid from your body?
After that, another option is to take a potassium-binding agent, either patiromer (Veltassa), sodium polystyrene sulfonate (Kayexalate), or sodium zirconium cyclosilicate (Lokelma).
What to do if you have too much potassium in your body?
You will also need to remove the extra potassium from your body -- these treatments include diuretics (water pills) and dialysis. If it’s not a crisis, you may still need medicines to help flush out the excess potassium, just not quite as urgently.
Do kidneys flush out potassium?
Normally, healthy kidneys flush out any extra potassium. But if you have kidney problems or some other conditions (such as type 1 diabetes, heart failure, or liver disease) or take certain medications, your body might not be able to do that as well as it should. Decide on Next Steps.
Can hyperkalemia be managed as an outpatient?
Think Long-Term. If your doctor finds that your hyperkalemia is mild, your condition may be something you can manage as an outpatient, meaning that you don’t have to stay in a hospital. You’ll know you’re on the mend when your potassium levels return to normal and stay that way.
How to treat hyperkalemia?
16 Patients should be asked about their use of over-the-counter nonsteroidal anti-inflammatory drugs and herbal remedies, since herbs may be a hidden source of dietary potassium.
What causes hyperkalemia in the kidney?
Causes of hyperkalemia are outlined in Table 1. Shifting of potassium from the cells to the extracellular space is a cause of transient hyperkalemia, while chronic hyperkalemia indicates an impairment in renal potassium secretion. The following discussion is a guide to the approach to the hyperkalemic patient.
What is the difference between hyperkalemia and potassium?
Hyperkalemia results either from the shift of potassium out of cells or from abnormal renal potassium excretion. Cell shift leads to transient increases in the plasma potassium concentration, whereas decreased renal excretion of potassium leads to sustained hyperkalemia. Impairments in renal potassium excretion can be the result ...
What is pseudohyperkalemia?
Pseudohyperkalemia, an artifact of measurement, occurs due to mechanical release of potassium from cells during phlebotomy or specimen processing. 6 This diagnosis is made when the serum potassium concentration exceeds the plasma potassium concentration by more than 0.5 mmol/L, and should be considered when hyperkalemia occurs in the absence of a clinical risk factor. Fist-clenching, application of a tight-fitting tourniquet, or use of small-bore needles during phlebotomy can all cause pseudohyperkalemia.
How does insulin affect potassium?
Insulin lowers the plasma potassium concentration by promoting its entry into cells. To avoid hypoglycemia, 10 units of short-acting insulin should be accompanied by a 50-g infusion of glucose, increased to 60 g if 20 units of insulin are given. 24. Beta-2 receptor agonists produce a similar effect.
How does potassium release?
Exercise, beta-blockers. During exercise, potassium is released from skeletal muscle cells and accumulates in the interstitial compartment, where it exerts a vasodilatory effect. The simultaneous increase in circulating catecholamines regulates this release by promoting cell potassium uptake through beta-adrenergic receptor stimulation.
What are the determinants of potassium distribution?
The most important determinants of potassium distribution between the intracellular and extracellular space are insulin and beta-adrenergic receptor stimulation.
What is the treatment for hyperkalemia?
In patients with severe hyperkalemia, treatment focuses on immediate stabilization of the myocardial cell membrane, rapid shifting of potassium to the intracellular space, and total body potassium elimination. In addition, all sources of exogenous potassium should be immediately discontinued; including intravenous (IV) and oral potassium supplementation, total parenteral nutrition, and any blood product transfusion. Drugs associated with hyperkalemia should also be discontinued (see Etiology). [ 64]
What is the FDA approved treatment for hyperkalemia?
Sodium zirconium cyclosilicate (Lokelma) was approved by the FDA in May 2018 to treat hyperkalemia in adults. It preferentially captures potassium in exchange for hydrogen and sodium, which reduces the free potassium concentration in the lumen of the GI tract, and thereby lowers the serum potassium level.
How long after hyperkalemia can you measure potassium?
Measurement of potassium levels at least 1, 2, 4, 6, and 24 hours after identification and treatment of hyperkalemia is recommended. [ 64] Discontinue any potassium-sparing drugs or dietary potassium. If the patient is taking digoxin, look for evidence of digitalis toxicity.
How much potassium does SPS lower?
SPS can decrease serum potassium by 2 mEq/L. Oral SPS is useful in patients with advanced renal failure who are not yet on dialysis or transplant candidates. One or more daily doses of 15 g can control mild to moderate hyperkalemia effectively, with little inconvenience to patients.
Is hyperkalemia aggressive?
The aggressiveness of therapy for hyperkalemia is directly related to the rapidity with which the condition has developed, the absolute level of serum potassium, and the evidence of toxicity. The faster the rise in the potassium level, the higher it has reached, and the greater the evidence of cardiotoxicity, the more aggressive therapy should be. ...
When to monitor potassium levels in the ED?
Measurement of potassium levels at least 1, 2, 4, 6, and 24 hours after identification and treatment of hyperkalemia is recommended. [ 64]
Can potassium supplements cause hyperkalemia?
In most cases, all 3 of those etiologic factors contribute to hyperkalemia. It is particularly important to reevaluate the use of potassium supplements (including salt substitutes) in patients with renal insufficiency or in patients taking medications that impair renal excretion of potassium.
What is the term for a high potassium level?
Hyperkalemia is a higher than normal level of potassium in the blood. Although mild cases may not produce symptoms and may be easy to treat, severe cases of hyperkalemia that are left untreated can lead to fatal cardiac arrhythmias, which are abnormal heart rhythms. You may be at risk for hyperkalemia because of:
What causes potassium to be low?

It can be difficult to diagnose hyperkalemia. Often there are no symptoms. When there are, symptoms may include nausea; a slow, weak or irregular pulse; irritability, paraesthesia (numbness), muscle weakness, diarrhea, abdominal cramping or sudden collapse if the heartbeat slows or stops.
Can too much potassium cause hyperkalemia?
If intake of potassium far outweighs the kidneys’ ability to remove it , or if kidney function decreases, there can be too much potassium and hyperkalemia may occur. Potassium and sodium concentrations play a crucial role in electric signal functioning of the heart’s middle thick muscle layer, known as the myocardium.
Can you stop taking potassium supplements?
A doctor may also advise stopping or reducing potassium supplements and stopping or changing the doses of certain medicines for heart disease and high blood pressure. Always follow your health provider's instructions about taking or stopping medicines.
Treatment
Mechanism of action
- Difficulty breathing
- Weak pulse
- Chest pain
- Signs of a heart attack
Overview
Side effects
- Hyperkalemia occurs when you have too much potassium in your blood. Because hyperkalemia is a sign that something else is going on in your body, treatment depends on what's causing it and whether the level of potassium in your blood is judged to be an emergency or not. Methods of treatment may include intravenous therapies, dialysis, diuretics, pot...
Usage
- Intravenous (IV) calcium immediately counteracts the effects that high potassium levels have on your cell membranes and stabilizes the electrical systems in your heart, nerves, and muscles. Because the effects only last up to 60 minutes, to work most effectively, it needs to be combined with IV insulin and glucose, which help push the potassium back into your cells. Potassium-rem…
Medical uses
- Also known as water pills, diuretics work by increasing the amount of potassium your body excretes into your urine. They're prescribed for both emergency and non-emergency hyperkalemic situations if you have normal or mild to moderately impaired kidney function, but not for severely impaired kidney function.
Administration
- Potential side effects of diuretics include increased urination, hypokalemia (low blood potassium levels), hyponatremia (low blood sodium levels), dizziness, headaches, dehydration, cramps in your muscles, joint disorders, and erectile difficulties.
Diet
- RAAS inhibitors spare potassium from being excreted in your urine, the opposite of how patiromer works. They are typically prescribed to people with heart failure, diabetes, and chronic kidney disease.
Symptoms
- Albuterol isn't used often and never by itself. But, it can work to lower potassium levels in people whose symptoms of hyperkalemia aren't getting any better despite treatment with calcium and insulin with glucose or for whom dialysis isn't an option.
Diagnosis
- It's typically administered with a nebulizer, which takes saline and albuterol and sprays it into a fine mist that you breathe in. If you can't tolerate a nebulizer, it can be administered through an IV instead. Using albuterol can make you shaky and make your heart beat faster.
