Calcium Deficiency Causes 

  • Less and inconsistent consumption of calcium

Not having adequate amounts of calcium, especially in childhood, makes a big difference in the way our body behaves. 

If the body doesn’t get enough quantities of a mineral during the time of its basic development, deficiency diseases are common. 

  • Lactose Intolerant

Lactose Intolerant individuals usually have a higher chance of developing calcium deficiency diseases, than others. This is because they are not able to consume dairy products, the primary source of calcium. 

  • Hormonal Alterations: 

Changes in the bodies of women can also result in a deficiency of calcium. This is usually seen after pregnancy. The hormonal transitions that the body goes through during the times of pregnancy can strip the body of its usual calcium proportions. 

Thus, the bone density of women also decreases with age and supplements should be taken for maintaining the level of calcium in our body. 

  • Prolonged medication due to certain diseases

This can also be the cause of calcium deficiency. Certain medicines may have side effects that cause a deficiency of calcium.

  • Genetic

The deficiency of calcium can be genetically passed down, family after family. Genetic causes are mostly not entirely curable but the amount of calcium can be controlled.

Thus, it corrodes the bones and makes them fragile and weak. The curtailing of bone density is known as osteopenia. It, in turn, causes osteoporosis. This makes the bones look naturally weak, thin and frail, prone to pains and injuries. 

Sprains and fractures can become frequent in such a condition. 

Muscle Ailments

Since calcium is directly associated with bones, muscles get involved as well. Calcium deficiency can result in the feeling of numbness in the hands and legs, as well as the area surrounding the mouth. 

Spasms and other kinds of muscle pains become quite frequent. Moreover, hindering the good condition of bones and muscles means experiencing discomfort while doing the most basic jobs like walking or running. 

Certain fatal symptoms of calcium deficiency are arrhythmias and severe convulsions. In very few cases, it leads to death as well. 

Dental Issues

When the body starts drawing calcium from the teeth, due to a lack of its intake, certain problems occur. Corrosion of the outer and inner layers of teeth makes them weaker from the roots and prone to irritation, decay, etc. 

These issues can also be found in children if they’re not made to consume calcium-rich foods.
