In general, calcium is essential because it:

  • Favors vitamin B12 absorption.
  • Allows blood to clot.
  • Is important for the transmission of nerve impulses and muscle contractions.
  • Contributes to the activation of many basic body enzymes.

What are the causes of hypocalcemia?

According to Dr. James L. Lewis, hypocalcemia can result from a disorder of the parathyroid glands, as well as diet, kidney disorders, or certain drugs.
Here are other causes of hypocalcemia:

  • Pancreatitis.
  • Hypomagnesemia.
  • DiGeorge syndrome.
  • Kidney failure.
  • Pseudohypoparathyroidism.
  • The consumption of certain drugs (such as anticonvulsants, bisphosphonates, and some antibiotics, among others).

However, the most common causes are:

  • Vitamin D deficiency (due to lack of sun exposure or poor diet).
  • Inadequate calcium intake.
  • Disorders that reduce calcium absorption.

The main symptoms of hypocalcemia

Although it doesn’t manifest with strong symptoms at first, as time passes (and there’s no treatment or improvements in diet or other lifestyle aspects), various discomforts appear, such as muscle cramps in the back and legs.

People with hypocalcemia may have dry, flaky skin, as well as weak and brittle nails, in contrast to thicker hair.

In advanced cases, hypocalcemia can cause a tingling sensation. In addition, it can affect the brain and cause confusion, trouble concentrating and remembering, delirium, depression, and hallucinations. Nevertheless, we should note that these symptoms disappear once the blood calcium levels are restored.

A medical professional can diagnose hypocalcemia with a simple blood test.

How’s hypocalcemia treated?

Treatment of hypocalcemia varies depending on the underlying cause and the patient. However, it’s common for doctors to prescribe calcium supplements and, in some cases, vitamin D supplements.

Calcium supplements are taken orally with the goal of normalizing blood calcium levels. Along with this, doctors often make diet recommendations.

  • Not only dairy products are rich in calcium. Also, you can find it in legumes, such as lentils or chickpeas.
  • Eggs, nuts, and broccoli are also very suitable foods to include in your diet.
  • Hypocalcemic patients should avoid excessive consumption of beverages that contain caffeine, as they can interfere nutrient absorption.
  • The key is to follow a balanced diet, which includes all the food groups in enough quantities.

Can it be prevented?

Yes, it’s possible to prevent hypocalcemia. How? Following a healthy lifestyle and getting periodic medical checkups.

While diet plays a key role, you should also exercise outdoors, as it has health benefits. Therefore, it’s advisable to take walks and take advantage of the sun’s rays to synthesize vitamin D.
