Thyrotoxicosis leading to Renal Tubular Acidosis presenting as periodic paralysis – A case report

Abstract

Periodic fl accid paralysis is related to loss of tone and power transiently and which occurs repeatedly over time. Etiologies like channelopathies, myasthenia gravis and thyroid disorders are common. There have been case reports of thyroid disorders leading to periodic paralysis. The pathophysiology attributed to it is the increased uptake of potassium by the cells in the thyrotoxic state. Thyrotoxicosis is also an uncommon cause for distal renal tubular acidosis.
