What are the symptoms of hyperparathyroidism?

Symptoms of hyperparathyroidism include effects on your bones due to absorption of calcium from bone, including brittle or weakened bones, bone pain, or lower back pain. Systemic symptoms related to hyperparathyroidism include thirst, increased urination, depression, personality changes, and loss of appetite, among others. Life-threatening symptoms associated with hyperparathyroidism include coma, stupor, or severe bone weakness and fractures.

Common symptoms of mild hyperparathyroidism

You may experience hyperparathyroidism symptoms daily or just once in a while. Many people with hyperparathyroidism do not even notice any symptoms, though at times any of these symptoms can be severe:

  • Abdominal pain
  • Bone, joint, or lower back pain
  • Changes in mood, personality or behavior
  • Fatigue
  • Increased thirst
  • Increased urine volume
  • Itching feeling
  • Muscle weakness or muscle soreness

Common symptoms of more severe hyperparathyroidism

In addition to all of the symptoms of mild hyperparathyroidism, you may experience symptoms of severe hyperparathyroidism including:

  • Abdominal pain
  • Bone fractures
  • Change in level of consciousness or alertness, such as passing out or unresponsiveness
  • Constipation
  • Difficulty with memory, thinking, talking, comprehension, writing or reading
  • Kidney stones
  • Loss of appetite
  • Loss of height
  • Nausea with or without vomiting

Serious symptoms that might indicate a life-threatening condition

In some cases, hyperparathyroidism can be life threatening if calcium levels get too high in your blood. Seek immediate medical care (call 911) if you, or someone you are with, have any of these life-threatening symptoms including:

  • Bone fractures, especially in the elderly
  • Change in level of consciousness or alertness, such as passing out or unresponsiveness
  • Change in mental status or sudden behavior change, such as confusion, delirium, lethargy, hallucinations or delusions
  • Coma
