Hypokalemic periodic paralysis is a condition in which affected individuals may experience paralytic episodes with concomitant hypokalemia (<2.5 mmol/L), and occasionally may develop late-onset proximal myopathy. The paralytic attacks are characterized by reversible flaccid paralysis usually leading to paraparesis or quadriparesis but typically sparing the respiratory muscles and heart [1]. The major triggering factors are carbohydrate-rich meal, vigorous exercise, viral illness, stress, emotional triggers. The age of onset of the first attack occurs before 16 years of age in 60% [1]; the frequency of attacks is highest between ages 15 and 35 and then decreases with age. We hereby report a case of primary (familial) hypokalemic periodic paralysis precipitated by carbohydrate rich food in an adolescent, successfully managed with potassium supplements.
