Thyroid gland (glandular thyroid) produces 3 hormones of utmost importance for the proper functioning of the entire human body.
- thyroxine (T4) and triiodothyronine (T3) – hormones that affect growth, manage metabolism, brain, bone and muscle development,
- kalcitonin – a hormone responsible for lowering calcium in the blood.
The part of thyroid gland is parathyroid gland (glandulae parathyreoidae) producing parathyroid hormone (PTH), which, in contrast to calcitonin, increases the amount of calcium and also regulates the amount of phosphorus in the blood.
Once the calcium level in the blood stream drops for some reason, parathyroid glands begin to excrete the parathyroid hormone responsible for transferring calcium from the bone. If the level of parathyroid hormone drops even more and the supply of calcium in the bones is no longer sufficient, tetanus and dangerous paralyzing muscle spasm can occur. Excessively rising calcium level in the blood subsequently cause secretion of the calcitonin hormone by the thyroid gland, thereby literally inhibits the production of parathyroid hormone.
It is therefore clear that everything is related to everything and the thyroid gland through hormones conducts the course of the human organism and interferes with all its processes.
If any thyroid gland disorder (hypofunction, hyperfunction, goitre …) has a synthetic hormone, the pituitary does not command the thyroid to produce its own. This process thus loses its natural function, gradually atrophies and becomes inoperable. In addition, it loses the possibility to form the parathyroid hormone and calcitonin by parathyroid hormones which are not present in the administration of synthetic hormones.
