Hypercalcemia: Symptoms, Causes, Diagnosis, Management and Treatment

In this blog we will read about the condition caused due to high calcium levels i.e Hypercalcemia.

Hypercalcemia is caused when there is too much calcium in the blood due to malabsorption or any other factors, too much calcium in blood can weaken our bones increase the risk of osteoporosis, and also affect the heart and brain.

Hypercalcemia often happens when the parathyroid gland releases too much hormone in the blood, hypercalcemia can also lead to cancer, Taking too much calcium and vitamin D can also lead to Hypercalcemia.

What is Hypercalcemia?

Hypercalcemia is the condition when there is excess calcium in the blood and Primary Hyperparathyroidism usually causes it, Hypercalcemia may be mild, acute or chronic(Lifelong)

Calcium is one of the important minerals that helps strengthen our bones and also helps in regulating the metabolism essential for the normal functioning of the body, Calcium in the body helps

Two Hormones called Parathyroid hormone and calcitonin help regulate the calcium level in your blood and bones, Vitamin D also helps in controlling the calcium level and helps absorb calcium from the food you eat to maintain the good calcium level in your blood.

Your body carefully controls the calcium level but certain medications and conditions can lead to hypercalcemia.

Calcium Normal Range

The normal range for different hypercalcemic conditions is given in the tabulated form below


Biological reference(Mg/dl)

Mild Hypercalcemia

10.5 to 11.9

Moderate Hypercalcemia

12.0 to 13.9 

Chronic(Hypercalcemic crisis)

14.0 to 16.0
