Calcium deficiency

Calcium is one of the most abundant minerals in the body. An average human body contains about 1 kg of calcium. It regulates normal heart rhythm, maintains structure of bone and teeth, aids in clotting of blood, contracting of muscles, and helps in proper functioning of nerves.

The total serum calcium levels below 8.8 mg/dL is considered as calcium deficiency. The primary symptoms include rough hair, brittle nail, dry skin, itching, cataracts (clouding of eye lens), and poor quality of teeth.

The sudden drop in calcium level may even lead to serious symptoms such as cardiovascular collapse, irregular heartbeat, seizures, and neuromuscular irritability. These symptoms need hospitalization.

Lactose intolerance, restrictive diets, liver and kidney diseases, pregnancy, menopause amongst others are known to increase its risk.

Daily consumption of foods rich in calcium such as milk, cheese, yogurt, spinach, kale, broccoli, and nuts are the best way to prevent calcium deficiency. Treatment includes consuming a calcium rich diet along with calcium and vitamin D supplements. Acute or severe calcium deficiency might require hospitalization.
