AI Article Synopsis
- Thyrotoxic periodic paralysis is a rare but serious consequence of hyperthyroidism, mainly affecting Asian men.
- A 14-year-old African American boy with Graves' disease experienced leg weakness due to hypokalemia and hyperthyroidism, which improved after potassium treatment and medication.
- Follow-up revealed he was stable and without hyperthyroid symptoms, highlighting the importance of checking thyroid function in kids with weakness and low potassium levels.
Article Abstract
Background: Thyrotoxic periodic paralysis is a rare complication of hyperthyroidism and is associated with hypokalemia and muscle paralysis. This condition is most commonly seen in Asian men.
Case Presentation: We report on a 14-year-old African American male with Graves' disease and intermittent asthma who presented with bilateral leg weakness. The patient demonstrated signs of thyrotoxicosis and laboratory evaluation revealed hypokalemia and hyperthyroidism. Following the administration of potassium supplementation clinical status improved and the patient was discharged home on a high dose of methimazole and propranolol. At a 6-month follow up visit, he was found to be clinically euthyroid and demonstrated no signs of hyperthyroidism or muscle weakness.
Conclusion: Children presenting with weakness and hypokalemia should be investigated for thyroid dysfunction. Correction of hypokalemia improves acute presentation, but the patient will remain at risk for paralysis until euthyroid state is achieved.

Introduction: Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare but severe complication of hyperthyroidism characterized by acute muscle weakness. This study reports the first case of THPP in an adolescent with type 1 diabetes mellitus (T1DM) and Graves' disease, triggered by high-dose insulin, high carbohydrate intake, and strenuous exercise. It highlights the clinical presentation, management, and implications of THPP in this context.

Thyrotoxic periodic paralysis (TPP) is a rare but significant complication of hyperthyroidism, characterized by episodes of muscle weakness or paralysis and associated hypokalemia. This case report details a 30-year-old Latin American male with a history of Graves' disease, presenting with acute muscle weakness and hypokalemia. The patient reported transient episodes of weakness over recent weeks, culminating in a severe episode prompting emergency evaluation.

One type of hypokalemic periodic paralysis that is associated with hyperthyroidism is called thyrotoxic periodic paralysis (TPP). TPP can be linked to any cause of hyperthyroidism, although Graves' disease is the most common cause. This sporadic variant of hypokalaemic periodic paralysis, thyrotoxic periodic paralysis, is characterized by rapid onset weakness in the proximal muscles.

Thyrotoxic periodic paralysis (TPP) is a rare complication primarily associated with thyrotoxicosis, particularly in individuals with Graves' disease. While more common in males aged 20 to 40, it can occur across all ethnic backgrounds. It is the most common type of acquired periodic paralysis.

Hypokalemia is a common laboratory finding in hospitalized patients, typically resulting from insufficient potassium intake, renal or gastrointestinal losses, or intracellular shifts. While the underlying cause is often easily identifiable, certain cases present diagnostic challenges, and if left unrecognized, the consequences can be life-threatening. We report a rare and atypical case of severe symptomatic hypokalemia as the initial presentation of newly diagnosed Graves' disease.
