Primary hyperparathyroidism is called primary hyperparathyroidism because the lesion is in the parathyroid gland. Treatment of primary hyperparathyroidism with symptoms or complications can be treated with surgical procedures. Surgery to remove the hyperplastic parathyroid tissue is a better treatment. During the surgery, we should closely monitor the patient’s blood calcium, and patients with asymptomatic hyperparathyroidism can be followed up regularly, and cimetidine can be applied to do medication to avoid hypercalcemic crisis. The above is for reference only. Please refer to the doctor’s instructions for specific medication and treatment.
