Why do I get tremors since my thyroid surgery?

Tremors are typically associated with a low calcium level in the body. This is due to hypoparathyroidism because of bruising or injury to the parathyroid glands during thyroid surgery. There are routinely 4 parathyroid glands that control your calcium level that lie below your thyroid gland. If you had your thyroid completely removed sometimes you can injure all 4 of these glands. Typically 5 of every 100 patients that have their thyroid completely removed will have temporary low calcium for up to 6 months as these glands have been bruised and need time to recover. These patients need some calcium supplements until their parathyroid glands recover. In 1 of every 100 patients that have their thyroid completely removed their calcium will remain low for life. These patients typically will not have recovery of their parathyroid glands and will require calcium supplementation for life.
