The main function of parathyroid hormone is to affect the metabolism of calcium and phosphorus in the body, mobilize calcium from bones, increase the concentration of calcium ions in the blood, and also act on the intestine and renal tubules to increase the absorption of calcium, thus maintaining the stability of blood calcium. If the parathyroid secretion function is low, the blood calcium concentration decreases and hand-foot convulsions occur; If the function is hyperactive, it will cause excessive bone absorption and fracture easily. Dysfunction of parathyroid gland will lead to abnormal ratio of calcium and phosphorus in blood.

In fact, the parathyroid gland is located in the thyroid gland. Generally, there are four, one pair on the left and one pair on the right, all of which are flat oval bodies, brown, slightly like soybeans. They are attached to the posterior margin of the lateral thyroid lobe, outside the thyroid capsule, and sometimes embedded in thyroid tissue. The upper pair of parathyroid glands is generally located near the middle of the posterior edge of the lateral thyroid lobe, and the next pair is near the inferior thyroid artery, about 1/3 below the gland.

The function of hormone secreted by parathyroid gland is to regulate calcium metabolism and maintain blood calcium balance. When the secretion is insufficient, it can cause the decrease of blood calcium and tetany. Hyperfunction leads to excessive bone resorption and easy fracture. Therefore, some people should consider whether the above symptoms are related to parathyroid dysfunction.

I found this because it is the most authoritative explanation.

Thyroid problems must be related to endocrine disorders. I am a hyperthyroidism caused by long-term endocrine disorders and have not been taken seriously.

If you go to the hospital, it's endocrinology.

Hehe, the main methods of conditioning are regular work and rest and moderate diet.

If you have symptoms such as emaciation and palpitation, seek medical advice promptly!
