It is possible to recover from parathyroid damage or not, depending on the severity of the damage. Thyroid surgery may cause damage to the parathyroid glands, which may lead to hypocalcemia, etc. If the damage is mild, the remaining parathyroid tissue will compensate for the damage, and the function of the parathyroid glands will return to normal, but if the damage is severe, the function of the parathyroid glands may not be able to return to normal because there is a certain limit to the compensation. Thyroid surgery should be performed with care to prevent damage to the parathyroid glands. After damage to the parathyroid glands, prompt medical attention is needed to correct electrolyte disorders, such as hypocalcemia.
