Can excess parathyroid hormone cause loss of energy?
Yes! One of the most common symptoms of parathyroid disease is low energy.
Excess parathyroid hormone (PTH) usually causes elevated calcium levels. Both the elevated PTH and elevated calcium levels cause problems throughout the body. The most common symptoms are often non-specific: fatigue, low energy, insomnia, aches and pains. These symptoms can be debilitating. Excess PTH can also lead to bone loss, osteoporosis, and fractures. Parathyroid disease can also lead to kidney stones, high blood pressure, cardiac arrythmias, and kidney failure. Often, it is the fatigue and loss of energy that cause the most significant impairments in quality of life, and that lead people to have parathyroid surgery.
