Possible causes of hypocalcaemia and correlation with vitamin D deficiency.

Hypocalcaemia is a pathological condition characterized by the presence in the blood of a very low amount of calcium, lower than normal, which can lead to the onset of various diseases. Not always this condition is due to a low intake of calcium through nutrition, indeed, most of the time the cause is to be found elsewhere.

The body has a large reserve of calcium in the bones, which draws to compensate for the low level of blood mineral. However it is not an infinite storage and it can be seriously affected by a very prolonged anemia, which causes the hypocalcaemia.

 

How calcium is managed in the body

To understand the causes of hypocalcaemia it is necessary to know how the body handles calcium. Malfunctions of this delicate mechanism can cause an important mineral deficiency.

In the blood calcium regulation depends on three components: vitamin D, which the human body cannot produce and who hires from outside, and two hormones, calcitonin and parathyroid hormone, both produced by parathyroid glands that are located near the thyroid and that regulate calcium metabolism.

These two hormones intervene to increase or decrease the level of calcium in the blood: calcitonin is dedicated to its elevation, through the removal of the mineral in the bones, which is then poured into the blood, while the parathyroid hormone, regulates its decrease, which occurs through the opposite process, that is, with the fixation of calcium on the bones.

Vitamin D3 contributes to the fixation of bone calcium, and a lack thereof causes a deficiency of the mineral reserve. A lowering of the level of calcium in the blood, then, may have important effects on health.

 

Most likely causes of hypocalcaemia

The causes of hypocalcaemia may be different.

The main ones are:

  • Reduced intake for prolonged periods (even years) of calcium, which in the long run cause a deficiency in the blood;
  • Vitamin D deficiency;
  • Parathyroid glands problems, which do not allow for the proper management of calcium in the blood;
  • Taking medications that prevent the absorption of calcium in the blood;
  • Specific diseases such as chronic renal failure that can interact with the proper metabolism of the mineral.

In particular cases, dictated by the intake of drugs or the presence of certain diseases, the doctor might prescribe intravenous calcium therapy.

Hypocalcaemia can also occur in the presence of other symptoms, of which vitamin D deficiency is certainly the most frequent but which in turn, may depend on two circumstances:

  • The metabolically active vitamin D3 is not taken by foods of animal origin, perhaps due to a diet that is exclusively based on vegetables or almost (vegetables only contain vitamin D2, the form that needs to be activated);
  • Lack of exposure to the sun, which activates vitamin D2 and transforms it into D3.

In both these cases it is important not so much to act by increasing the amount of calcium taken with food or by taking supplements but as just as to integrate vitamin D3 through specific natural products.

The choice of vitamin D supplement is essential. Not all products on the market, in fact, contain the metabolically active form of vitamin D, i.e. D3.

Vitamin D deficiency, therefore, represents the most frequent cause of hypocalcaemia, which, however, can be diagnosed through blood tests and easily resolved with a natural supplement such as D3K1.
