Causes of Hyperkalemia Hyperkalemia is caused by excess potassium intake, impaired potassium excretion, or transcellular shifts. The etiology of hyperkalemia is often multifactorial, with impaired renal function, medication use, and hyperglycemia as the most common contributors. Because healthy individuals can adapt to excess potassium consumption by increasing excretion, increased potassium intake is rarely the sole cause of hyperkalemia, and underlying renal dysfunction is common #Diagnosis #Hyperkalemia #Differential #Causes
