What causes calcium deficiency?

Calcium deficiency, or hypocalcemia, is a condition in which calcium levels in the blood are below normal values. This alteration can have several causes that affect the regulation and absorption of calcium in the body.

If you're wondering what causes calcium deficiency, read on for a detailed look at the factors that can contribute to this condition:

  • Hypoparathyroidism: This is a condition where the parathyroid glands produce too little parathyroid hormone (PTH), which helps to regulate calcium levels in the body. Without enough PTH, calcium levels in the blood can drop too low, leading to symptoms such as muscle cramps, seizures, and tingling in the fingers or lips.

  • Vitamin D deficiency: Vitamin D is necessary for the absorption of calcium from the diet. Without enough vitamin D, the body may not be able to absorb enough calcium, which can lead to weak bones, muscle weakness, and other symptoms.

  • Renal insufficiency: The kidneys are responsible for filtering excess calcium out of the blood and excreting it in the urine. In renal insufficiency, the kidneys are not functioning properly and may not be able to eliminate enough calcium, leading to high levels of calcium in the blood.

  • Medications: Some medications, such as proton pump inhibitors (PPIs), can interfere with calcium regulation in the body and lead to high or low levels of calcium.

  • Pseudohypoparathyroidism: This is a rare genetic disorder where the body's tissues do not respond properly to parathyroid hormone, even if PTH levels are normal. This can lead to low calcium levels and other symptoms.

  • Hypomagnesemia: Magnesium is also important for calcium regulation in the body. Low magnesium levels can lead to low calcium levels and other symptoms.

  • Pancreatitis: Inflammation of the pancreas can disrupt the body's calcium balance and lead to high or low levels of calcium in the blood.


These are just some of the causes of calcium deficiency. Proper diagnosis and treatment are essential to address hypocalcemia and prevent complications. Consult a medical professional if you have symptoms or suspect this condition.
