The parathyroid glands are four pea-sized glands. They are located next to the thyroid gland in the neck. The glands secrete the parathyroid hormone (PTH). PTH helps to regulate the level of calcium in the blood.

In hypoparathyroidism, there is not enough PTH secreted. This causes low levels of calcium in the blood. Low blood calcium is known as hypocalcemia.

Hypoparathyroidism may be caused by:

  • Removal of the parathyroid glands
  • Underlying autoimmune disorders
  • Absence of the parathyroid glands at birth
  • Damage to the parathyroid glands
  • Genetics conditions, such as DiGeorge syndrome
  • Magnesium deficiency due to alcohol use disorder and/or malnutrition
  • Other causes, such as metal overload from iron, magnesium, or aluminium

In some cases, a cause cannot be found.

Risk Factors

Factors that may increase your chance of hypoparathyroidism include:

  • Multiple autoimmune disorders
  • Thyroid or parathyroid surgery
  • Family history of hypoparathyroidism


Hypoparathyroidism does not always cause symptoms. If symptoms do develop, they may include:

  • Weakness
  • Muscle cramps or twitching
  • Pain
  • Difficulty with walking
  • Tingling around the mouth, fingers, and toes
  • Excessive nervousness
  • Loss of memory
  • Mood swings
  • Anxiety
  • Blurred vision due to cataracts
  • Thin, brittle nails
  • Dry and scaly skin
  • Seizures


You will be asked about your symptoms and medical history. A physical exam will be done.

Your bodily fluids may be tested. This can be done with:

  • Blood tests
  • Urine test

Images may be taken of your bodily structures. This can be done with:


Talk with your doctor about the best plan for you. Treatment options include the following:

Calcium and Vitamin D Supplementation

Calcium and vitamin D will usually be taken indefinitely. They are often taken by mouth.

Calcium may be given by injection. This is done when immediate symptom relief is needed.


There are no current guidelines to prevent hypoparathyroidism.
