​What Are the Causes of Calcium Deficiency

What Are the Causes of Calcium Deficiency?

• Diet. An unhealthy diet is the main cause of calcium deficiency. According to data from the USDA, 78% of women and 87% of teenage girls are calcium insufficient. Only 55% of men obtain sufficient calcium from foods. Hence it is not surprising that osteoporosis is now a serious health issue in the US.

• Parathyroid hormone. Parathyroid hormones regulate calcium concentrations in the blood. Low blood calcium triggers the secretion of parathyroid hormones from the parathyroid gland. Parathyroid hormones then release calcium from the bones and elevate blood calcium levels. When blood calcium is too high, the body will attenuate the secretion of parathyroid hormones. Parathyroid hormone disorder can contribute to problems related to calcium deficiency. 

Prevention and Treatment of Diseases 

• Prevention. Meta-analysis confirms that calcium can help prevent bone fractures (46), preeclampsia (97), and colorectal cancer (56). 

• Treatment. Calcium supplements help treat hypertension (78).
