NCT ID NCT07597096

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether taking vitamin D3 along with calcium for a week before total thyroidectomy prevents symptomatic low calcium levels after surgery better than calcium alone. 124 adults with multinodular goiter will be randomly assigned to one of the two groups. After surgery, they will be monitored for symptoms and blood calcium levels for 14 days.
