After thyroidectomy, calcium supplementation is usually not needed if the blood calcium is normal.
Some patients may damage the parathyroid glands after hemithyroidectomy, resulting in hypocalcemia, which may be manifested as numbness around the mouth, twitching of hands and feet, in which case calcium supplementation is needed, either intravenous calcium gluconate or oral calcium tablets.
If there is no hypoparathyroidism and hypocalcemia, routine calcium supplementation is usually not needed, and you can get more sunshine in your daily life and eat more calcium-rich foods in moderation, such as milk, shrimp, eggs, and so on.
Blood calcium and parathyroid hormone levels should be checked after hemithyroidectomy, and the need for calcium supplementation should be chosen under the guidance of a doctor.
