Parathyroid hormone is usually higher than 70 pg/ml and the presence of a parathyroid adenoma calls for surgery. In the case of hyperparathyroidism, which is not severe, conservative treatment is usually recommended, and surgery is considered if it is not effective. Under normal circumstances, the value of parathyroid hormone is 0-70pg/ml, if the current parathyroid hormone is more than 70pg/ml, it is considered abnormal, may be suffering from hyperparathyroidism, this situation can be treated conservatively first, if the conservative treatment is not effective, then consider surgery. If the parathyroid hormone value exceeds 70pg/ml and the diagnosis is confirmed to be a thyroid adenoma, surgical resection is usually recommended as soon as possible to avoid the gradual increase of the tumor that may compress the surrounding tissues and cause adverse reactions. If the parathyroid hormone value is high, regular observation and pathological biopsy are recommended to analyze the cause of the disease and then take regular treatment to control the progress of the disease.
