Summary

This study looked at 90 children aged 6 to 12 with night-time bedwetting and low vitamin D levels. It compared three treatments: vitamin D alone, desmopressin alone, or both together. The goal was to see which approach reduced wet nights the most over 3 to 6 months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Vitamin D and desmopressin
What this could lead to: If successful, this could show that vitamin D supplementation alone or combined with desmopressin is a safe and effective way to reduce bedwetting in children with low vitamin D levels.
What could go wrong: This is a small, completed trial with only 90 children, so results may not apply to all kids. Also, vitamin D deficiency may not be the main cause of bedwetting for everyone.
