Rhabdomyolysis in a Young Patient due to Hypothyroidism without Any Precipitating Factor

Hypothyroidism is characterized by decreased hormone production, which results in various clinical manifestations in different organ systems. Muscular symptoms are common in patents with clinical hypothyroidism which includes muscle cramps, myalgia, and mild to moderate elevation of creatinine kinase less than five times the upper limit of normal. However, rhabdomyolysis due to hypothyroidism is rare and in most of the reported cases a precipitating factor has been found. We report a unique case of a 35-year-old male with no past medical history who presented with rhabdomyolysis due to newly diagnosed hypothyroidism without any precipitating factors and was treated successfully with intravenous fluids and levothyroxine.
