Living with Hypoparathyroidism

A hormone condition in which the parathyroid glands make too little parathyroid hormone, causing low calcium.

Understanding Hypoparathyroidism

Hypoparathyroidism is a hormone condition in which the parathyroid glands in the neck do not make enough parathyroid hormone (PTH).

Common signs include belly pain, brittle nails, cataracts, dry hair and skin, muscle cramps, tetany (muscle spasms), pain in the face, legs, and feet, seizures, and tingling. Children may have weak tooth enamel. It may be caused by injury to the parathyroid glands, for example during surgery.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes these:

  • Muscle cramps and spasms (tetany)
  • Tingling feelings
  • Belly pain
  • Brittle nails
  • Dry hair and skin
  • Seizures

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
