Assessing perioperative body weight changes in patients thyroidectomized for a benign nontoxic nodular goitre.

Compared to nonthyroidectomized patients, thyroidectomized patients experienced significant weight increases at post 6 and 12 months. The extent of thyroidectomy did not affect the extent of weight gain. Younger age and higher baseline thyroid stimulating hormone were significant factors of weight gain at post 12 months.
