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.
