Tyreotoksisk periodisk paralyse

Thyrotoxic periodic paralysis is a rare and serious complication of hyperthyroidism.BackgroundThyrotoxic periodic paralysis is a rare and serious complication of hyperthyroidism.A man in his thirties of Asian descent, with non-compliant Graves' disease, presented with extremity paresis. Emergency blood tests revealed severe hypokalaemia, leading to a diagnosis of thyrotoxic periodic paralysis. The combination of uncontrolled hyperthyroidism, Asian ethnicity, paralysis, and severe hypokalaemia without other causes defined the diagnosis. Acute treatment involves non-selective beta-blockers, addressing hyperthyroidism, and potassium supplements.Case presentationA man in his thirties of Asian descent, with non-compliant Graves' disease, presented with extremity paresis.

If triggered by hyperthyroidism, as in Graves' disease, surgery or radioiodine is strongly indicated for definitive treatment. It is noteworthy that euthyroid patients cannot develop thyrotoxic periodic paralysis.InterpretationSwift recognition of thyrotoxic periodic paralysis is crucial for timely and life-saving treatment.
