Background
Bowel preparation prior to colonoscopic examination is generally considered a safe process. Hyponatremia is a complication that has been reported in literature during bowel preparation. Individuals who develop severe symptomatic hyponatremia are often older and have comorbidities such as hypothyroidism, chronic kidney disease, or adrenal insufficiency. However, other mechanisms and circumstances can also lead to this potentially fatal complication.
Case presentation
We present a unique case of a patient who developed seizure prior to colonoscopy due to acute hyponatremia without any well-known risk factors. With the subsequent diagnosis of water intoxication, the use of desmopressin was believed to have contributed to this serious complication.
Conclusion
In addition to the use of certain well-documented medications and the presence of comorbidities that can lead to hyponatremia, clinicians should also be aware of the use of desmopressin as an important risk factor. Thorough history taking can guide individualized bowel preparation regimens to minimize the risk of undesired complications.
