Popis: Abstract Background Primary polydipsia is commonly seen in patients with psychiatric illnesses. Excess water intake is also seen in patient with anorexia and anticholinergic medications. We report a patient who had hyponatraemia and rhabdomyolysis after consuming excess water for ureteric calculus. Case presentation A healthy middle-aged male presented with an episode of generalized tonic-clonic seizure and reduced level of consciousness preceded by consumption of excess water. He was recently diagnosed to have a ureteric calculus and was advised to consume plenty of water. On examination, he was disoriented in place, person and time. Except for the generalized diminished reflexes, other neurological and systemic examinations were normal. He had severe hyponatraemia, mild hypokalaemia and myoglobulinuria. His serum creatinine phosphokinase and aspartate aminotransferase were markedly elevated. The diagnosis of rhabdomyolysis in the setting of acute water intoxication was made. Optimum fluid and electrolyte management achieved a dramatic recovery of consciousness, hyponatraemia and rhabdomyolysis. Discussion The patient has had excess water intake due to a compulsive act in the background fear of ureteric calculus. Such act could lead to severe hyponatraemia and rhabdomyolysis. Therefore, future similar acts could be prevented by proper medical advice. Further, emergency physicians should be vigilant for rhabdomyolysis in patients with hyponatraemia or hypokalaemia.
