Conclusion:
In conclusion, our case highlights a rarely seen phenomenon in
pregnancy. Hyponatremia secondary to polydipsia causing seizures in the
peripartum period is an uncommon occurrence. Although severe
hyponatremia is not a common cause of seizure in laboring mother,
physician should always consider all possible medical and obstetric
causes of seizure. In addition, mid-level providers such as midwives
need to be educated about the risks of excessive water drinking during
pregnancy leading to hyponatremia.
