  • Title: Thyrotoxic hypokalemic periodic paralysis triggered by high carbohydrate diet.
    Author: El-Hennawy AS, Nesa M, Mahmood AK.
    Journal: Am J Ther; 2007; 14(5):499-501. PubMed ID: 17890941.
    Abstract:
    Thyrotoxic hypokalemic periodic paralysis is an uncommon disorder characterized by elevated thyroid hormone, muscle weakness or paralysis, and intracellular shifts of potassium leading to hypokalemia. This article presents a case of thyrotoxic hypokalemic periodic paralysis in a 22-year old Hispanic man with nonfamilial thyrotoxic hypokalemic periodic paralysis triggered by a high carbohydrate diet. Laboratory studies showed elevated thyroid hormone, decreased thyroid-stimulating hormone, and hypokalemia. Rapid reduction in thyroid hormone levels by giving antithyroid drugs such as propylthiouracil and prompt potassium therapy with frequent measurements of serum potassium levels during therapy to avoid catastrophic hyperkalemia when potassium starts to shift back from intracellular to extracellular compartments can lead to successful outcome.
