title: [How I investigate ... dyskalemia].
abstract: Potassium is the most important intracellular cation, playing a role in neuromuscular excitability. Dyskalemia is common. The consequence of this ionic perturbation could be serious related to its magnitude. Thus a quick etiological approach and a medical intervention are needed to rapidly correct this potentially lethal ionic disturbance and prevent its recurrence.
