Thyrotoxic periodic paralysis (TPP) is a rare reversible cause of paralysis and cramping. TPP is usually precipitated by common causes of thyrotoxicosis such as Grave disease or multinodular goiter. TPP precipitated by exogenous triiodothyronine (T3) intake is an extremely rare occurrence with only 3 cases reported to date. We now report a 24-year-old healthy manual laborer who developed quadriparesis during a period of rest after heavy exertion and carbohydrate intake. He had severe hypokalemia (potassium level 1.9 mmole/L). Correction of his hypokalemia reversed the paralysis without rebound hyperkalemia. After a detailed history review, he reported that he had been consuming nutraceuticals containing T3 for 1 month to lose weight, and laboratory studies confirmed factitious T3 toxicosis. There was no evidence of renal or gastrointestinal potassium wasting. This episode of TPP was the first manifestation of thyrotoxicosis in this patient, and avoidance of T3 intake prevented more episodes.

BACKGROUND Thyrotoxic periodic paralysis (TPP) is commonly observed in patients with acute paralysis and hyperthyroidism. However, there is a possibility of secondary causes of hypokalemia in such a setting. CASE REPORT Herein, we present the case of a 38-year-old woman with untreated hypertension and hyperthyroidism. She presented with muscle weakness, nausea, vomiting, and diarrhea since one week. The initial diagnosis was TPP. However, biochemistry tests showed hypokalemia with metabolic alkalosis and renal potassium wasting. Moreover, a suppressed plasma renin level and a high plasma aldosterone level were noted, which was suggestive of primary aldosteronism. Abdominal computed tomography confirmed this diagnosis. CONCLUSIONS Therefore, it is imperative to consider other causes of hypokalemia (apart from TPP) in a patient with hyperthyroidism but with renal potassium wasting and metabolic alkalosis. This can help avoid delay in diagnosis of the underlying disease.
