The Claim

In patients with benign multinodular goiter, total thyroidectomy is associated with a substantially higher risk of both transient and permanent hypocalcemia compared to hemithyroidectomy.

In plain English

Patients with benign multinodular goiter who undergo total thyroidectomy experience a higher rate of low blood calcium levels, both short-term and long-term, than those who undergo removal of only one lobe of the thyroid.

See the scientific wording

The risk of transient and permanent hypocalcemia after thyroid surgery is substantially higher with total thyroidectomy than with hemithyroidectomy in patients with benign multinodular goiter, supporting the need for preoperative counseling and postoperative monitoring tailored to surgical extent.

Why this might work

Removing the entire thyroid gland often damages or cuts off blood supply to the nearby parathyroid glands, which stop producing a hormone that keeps blood calcium levels normal. Without this hormone, bones release less calcium and kidneys reabsorb less calcium, causing calcium levels in the blood to drop.

    This study found that people who had their whole thyroid removed were much more likely to have low calcium levels after surgery than those who had only half removed. So yes, patients getting their entire thyroid out should be warned and watched more closely.
