Hypocalcaemia: causes, symptoms and treatment

Among the many pathological conditions that you can discover through a diagnostic test as simple as hematologic analyses, there is the low presence of calcium in the blood. This condition is called hypocalcaemia. Even if the diagnosis is simple, it is more complex to looking back at the causes that lead to this condition.

First of all, before making assumptions about the causes, it is necessary to understand the mechanism that regulates the presence of calcium in the body.


The regulation of calcium.

The regulation of calcium levels in the body depends essentially on three molecules. The first is vitamin D. The others are hormones produced by particular organs, which are located in the neck and which regulate the concentration of the mineral, respectively upwards and downwards. These hormones are called calcitonin and parathyrin.

Greatly simplifying, the regulatory mechanism in the blood happens more or less as follows: the level of calcium rises and falls continuously, activating the production, alternately, of the two regular hormones. Vitamin D placed calcium in the bones when it reaches high level while calcium is taken from the bones when it is low. Bones therefore represent the body’s calcium reserve.

Calcium is integrated in the body by the diet. It is consistently eliminated both through the urine, either through breastfeeding due to the muscles contraction.

When there is an imbalance between the incoming and outgoing of calcium, the parathyroid start to work badly or arises a shortage of vitamin D which is an essential element for the regulation of blood mineral so to avoid the onset of hypocalcaemia.

Causes of hypocalcaemia.

As well as therapies, the causes of hypocalcaemia are different. The most frequent are:

  • Hypoparathyroidism, consisting of a low activity of the parathyroid glands that allow adjustment of calcium through hormonal secretions;
  • Low and prolonged intake of calcium in the diet or for intestinal problems;
  • Vitamin D deficiency, which does not allow the transfer of calcium from the bones.
  • Some acute inflammations;
  • Use of drugs that interact with calcium metabolism;
  • Chronic renal failure: kidney as a matter of fact plays an active role in calcium metabolism.

There is no single therapy for hypocalcaemia. However, generally in all cases of hypocalcaemia, symptoms due to this prolonged condition can be prevented by administering calcium and vitamin D, and by monitoring the level of the mineral in the organism, more or less regularly. Of course, specific therapy must be take into account to solve the problem that caused the calcium deficiency because this condition is a symptom of a primary pathology that should be investigated and resolved.

Calcium and Vitamin D integration.

In case of hypocalcaemia, it is important to integrate both calcium and vitamin D.

Calcium supplementation is usually done by the diet with foodstuff rich of it. In severe cases is however necessary to use food supplements based on calcium lactate, calcium chloride or calcium gluconate.

Compared to foods rich in calcium (such as milk and cheese), the supplements bring only calcium, easy to absorb. This allows restoring a normal level of calcium even in those people who should take cheese to avoid hypocalcaemia but that they may not due to the increasing of lipids. This is, for example, the case of obese patients.

Food supplementation is useful in the long term so to avoid falling into a condition of hypocalcaemia.

Vitamin D deficiency causes hypocalcaemia, so it is always appropriate to supplement it if the levels are low. In fact, it is of little use to supplement calcium if it is not absorbed at the intestinal level, or if the calcium in the bones is present but the vitamin D deficiency does not allow its extraction and release into the bloodstream.

D3K1 is a supplement composed of vitamin D3, the most active form of vitamin, which removes calcium from the bones to put it into the blood. It therefore allows compensating for the absence of this vitamin and vitamin K, which instead allows a greater absorption of intestinal calcium. Thanks to the presence of vitamin K, the calcium dietary in equal intake, will join organism in larger quantities, avoiding its deleting through the feces. By taking the D3K1 supplement will not be necessary to supplement calcium with specific products. You should just eat foods rich in calcium.

It should be noted that, it is very important to repeat blood tests within a few weeks just to learn if therapy is working and the level of calcium in the blood is increasing, When the disease is resolved, it will still be advisable to repeat the tests at least once every three months, to keep the situation under control.
