Hyperkalemia in the tropics: multiple causes and a not so common presentation—a case report

Abstract

Abstract Background Hyperkalemia is an electrolyte abnormality with potentially life-threatening consequences. But all cases of hyperkalemia need not be symptomatic either. The feared consequence of hyperkalemia is that on the heart, it can induce fatal arrhythmias; rarely, it can present with neuromuscular signs. Most cases of hyperkalemia can be attributed to a single cause. Rarely, it can be multifactorial. Case presentation From the province of Kerala in India, we describe an elderly gentleman with severe hyperkalemia, who presented with quadriparesis. He had ECG changes consistent with hyperkalemia. Diverse causes were involved at the same time for the hyperkalemia. An uncommon cause observed was a diet rich in tropical fruits. As he did not respond to conservative (medications) measures, he had to be dialyzed. With dialysis, there was a rapid neurological recovery, and the potassium levels had improved. Conclusions In patients presenting with ascending paralysis, especially old people with morbidities, one differential diagnosis to be considered is hyperkalemia. Once hyperkalemia is confirmed, in addition to medications and illnesses, the preceding diet should also be enquired, especially the intake of fruits. In all, a good history in such a case is without a doubt imperative.
