This is due to the ability of the kidneys to adapt to increasing serum potassium concentrations. In patients with renal compromise potassium homeostasis can become impaired. Palmaria palmata dulse is an edible seaweed known to be very rich in potassium. We report a case of hyperkalemia precipitated by the consumption of dulse by a patient with known renal disease. Case Presentation A 66-year-old Caucasian woman with diabetes and chronic renal disease presented to our emergency department with nausea vomiting and worsening malaise which had been present for less than a day. She had undergone electrocardiogram monitoring which showed bradycardia and periods of asystole. Our patient denied any other symptoms. Laboratory analysis revealed a serum potassium level of mmol L normal range to mmol L . Although our patient was taking some medications known to influence renal function the only recent change that she could recount was that she had consumed approximately 200 g of dulse within the preceding 24 hours. A diagnosis of hyperkalemia was made and the patient was treated successfully and discharged home in her pre-morbid state. Conclusion To the best of our knowledge this is the first published report of hyperkalemia due to dulse consumption. Dulse is high in potassium with concentrations upwards of 34 times greater than that found in bananas. Caution should be taken in prescribing medications with potential adverse renal effects for patients with known renal impairment. In such instances renal function .
