Metrics details. To review the mechanisms of action, expected efficacy and side effects of strategies to control hyperkalemia in acutely ill patients.

Potassium Disorders: Hypokalemia and Hyperkalemia

Charytan D, Goldfarb DS. Indications for Hospitalization of Patients With Hyperkalemia. Arch Intern Med. For comparison, we selected a series of patients with a similar degree of hyperkalemia who were treated as outpatients. Hyperkalemia was classified as minimal, moderate, or severe. The causes of hyperkalemia were identified, and the therapeutic maneuvers used were ascertained.

Without potassium, we could not live. The electrolyte is responsible for a number of essential life functions. Not only is potassium responsible for regulating water balance in the body, it keeps the heart pumping, the muscles contracting, the gut digesting, and your nerves firing. That said, too much of a good thing can be harmful. High potassium, medically known as hyperkalemia , is a common laboratory finding.

Pathogenesis, diagnosis and management of hyperkalemia

Common causes of hyperkalemia include kidney failure , hypoaldosteronism , and rhabdomyolysis. Initial treatment in those with ECG changes is salts, such as calcium gluconate or calcium chloride. Hyperkalemia is rare among those who are otherwise healthy. The symptoms of an elevated potassium level are generally few and nonspecific. Decreased kidney function is a major cause of hyperkalemia. This is especially pronounced in acute kidney injury where the glomerular filtration rate and tubular flow are markedly decreased, characterized by reduced urine output.

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. Potassium is a mineral that is crucial for normal cell function in the body, including heart muscle cells. The body gets potassium through foods. The right level of potassium is key. An above normal level of potassium can interfere with proper electric signals in that muscle layer and lead to different types of heart arrhythmias. It can be difficult to diagnose hyperkalemia.

Signs and Symptoms of Hyperkalemia

Patient information : See related handout on potassium , written by the authors of this article. Hypokalemia and hyperkalemia are common electrolyte disorders caused by changes in potassium intake, altered excretion, or transcellular shifts. Diuretic use and gastrointestinal losses are common causes of hypokalemia, whereas kidney disease, hyperglycemia, and medication use are common causes of hyperkalemia. When severe, potassium disorders can lead to life-threatening cardiac conduction disturbances and neuromuscular dysfunction. Therefore, a first priority is determining the need for urgent treatment through a combination of history, physical examination, laboratory, and electrocardiography findings.

Without potassium, we could not live. The electrolyte is responsible for a number of essential life functions. Not only is potassium responsible for regulating water balance in the body, it keeps the heart pumping, the muscles contracting, the gut digesting, and your nerves firing.

Hyperkalemia is a medical term for when a person has higher than normal levels of potassium. Usually, people with hyperkalemia do not have any symptoms, which makes it challenging for a doctor to diagnose. The leading causes of hyperkalemia are chronic kidney disease , uncontrolled diabetes , dehydration , having had severe bleeding, consuming excessive dietary potassium , and some medications.

There have been significant recent advances in our understanding of the mechanisms that maintain potassium homoeostasis and the clinical consequences of hyperkalemia. In this article we discuss these advances within a concise review of the pathophysiology, risk factors and consequences of hyperkalemia. We highlight aspects that are of particular relevance for clinical practice. Hyperkalemia occurs when renal potassium excretion is limited by reductions in glomerular filtration rate, tubular flow, distal sodium delivery or the expression of aldosterone-sensitive ion transporters in the distal nephron. Accordingly, the major risk factors for hyperkalemia are renal failure, diabetes mellitus, adrenal disease and the use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers or potassium-sparing diuretics.

Professional Reference articles are designed for health professionals to use. You may find the Dietary Potassium article more useful, or one of our other health articles. NICE has issued rapid update guidelines in relation to many of these.

Hyperkalemia is a frequent finding in patients with chronic kidney disease CKD. This increase in serum potassium levels is associated with decreased renal ion excretion, as well as the use of medications to reduce the progression of CKD or to control associated diseases such as diabetes mellitus and heart failure. Hyperkalemia increases the risk of cardiac arrhythmia episodes and sudden death. Thus, the control of potassium elevation is essential for reducing the mortality rate in this population. Initially, the management of hyperkalemia includes orientation of low potassium diets and monitoring of patients' adherence to this procedure.
