Here is an article prepared for the readers of your website:
1. Dietary Deficiency
The most common cause is a lack of calcium-rich foods. Not including milk, dairy products, leafy vegetables, and nuts in the diet in the right amount can lead to calcium deficiency in the long run.
2. Vitamin D Deficiency
The body needs vitamin D to absorb calcium from the food we eat. If the body is deficient in vitamin D, no matter how much calcium we eat, it will not reach the blood.
3. Hormonal Changes
The calcium level in the body is controlled by the parathyroid glands located behind the thyroid gland in the neck. Decreased function of these glands (Hypoparathyroidism) can cause calcium levels to decrease significantly.
4. Age and Hormonal Changes (in women)
As we age, bone density decreases. Especially in postmenopausal women, the decrease in estrogen hormone levels causes calcium loss from bones and diseases such as osteoporosis.
5. Kidney diseases
When the kidneys fail, the amount of phosphorus in the body increases and calcium is excreted in excess through the urine. This can lead to a decrease in blood calcium levels.
6. Use of certain medications
Long-term use of seizure medications, steroids, and some acid-reducing medications can interfere with the body’s absorption of calcium.
Symptoms of calcium deficiency:
Muscle cramps and pain.
Broken nails.
Weak teeth.
Tingling and numbness in the limbs.
Sudden bone fractures.
