Multiple Causes of Hyponatremia: A Case Report.

OBJECTIVE

To present a case with 4 different potential causes of hyponatremia.

METHODS

The patient presented with the following symptoms: nausea, vomiting, diarrhea, and dark urine after drinking large amounts of fluids that included alcohol and caffeine. Laboratory, microbiological, and morphological examinations revealed the existence of severe hyponatremia and acute poststreptococcal glomerulonephritis. The patient developed acute symptomatic seizures and coma. Gradual normalization of the sodium level led to a recovery of consciousness.

CONCLUSIONS

Treatment with hypertonic sodium, fluid restriction, and antibiotics led to a complete recovery. In the case of multiple causes of hyponatremia, it is necessary to treat all causes.
