Dropped head syndrome (DHS) is known entity and has multiple causes. Dropped head syndrome has been reported both in hypokalemia secondary to several causes and in hypothyroidism as such. But its association with hypothyroidism and hypokalemia has not been reported so far. We present a case of DHS associated with hypothyroidism and hypokalemia. A 35-years-woman presented with dropped head syndrome. Biochemical evaluation revealed hypokalemia and hypothyroidism. Other causes of hypokalemia have been ruled out. The patient responded well to intravenous potassium initially but after institution of thyroxine potassium again started falling down. Therefore oral potassium chloride was continued in small doses for next four weeks. At end of six weeks, her TSH normalized and potassium was maintained in normal range without replacement.
