In a woman suffering from insulin-dependent diabetes mellitus, hypokalemic paralysis developed acutely following an episode of diabetes decompensation. During the treatment of this episode, as soon as serum potassium levels were restored to normal values, a marked increase in muscular excitability with an electromyographic picture of myotonia was observed. The patient showed signs of chronic muscle denervation that accounted for an increased sensitivity to potassium-induced depolarization and contraction and that might have been responsible for the appearance of myotonia during potassium repletion.
