The parathyroid glands are located behind the thyroid at the bottom of the neck and produce parathyroid hormone. Hyperparathyroidism occurs when these glands produce too much parathyroid hormone. Causes include problems with the parathyroid glands, gland enlargement, or a gland tumor.It can cause problems with vitamin D, calcium, osteoporosis and kidney issues.
Your doctor may ask these questions to check for this disease:
Treatment involves medication and/or surgery to remove the parathyroid glands to avoid complications.

Q.
Always Tired and Aching? Why Your Parathyroid is Overactive & Medical Next Steps
A.
Persistent fatigue and aching can stem from hyperparathyroidism, where overactive parathyroid glands raise PTH and blood calcium, leading to bone loss, kidney stones, digestive issues, and mood or cognitive changes. There are several factors to consider; see below for key symptoms, risk clues, and how this condition can be easily missed. Next steps include speaking with a clinician about serum calcium and PTH testing, vitamin D and kidney function labs, bone density scanning, and imaging to locate an overactive gland; treatment ranges from highly effective minimally invasive surgery to monitored care or medications, depending on severity. Seek urgent care for signs of severe hypercalcemia such as confusion, extreme weakness, dehydration, or abnormal heart rhythms, and see below for important details that could change your plan.

Q.
Always Tired? Why Your Parathyroid is Failing & Medically Approved Next Steps
A.
Always tired with brain fog or muscle weakness? Parathyroid disorders that push calcium too high or too low are an often overlooked, treatable cause and can also trigger bone loss, kidney stones, mood changes, and heart rhythm problems; see below for the key differences between overactive and underactive parathyroid disease. Medically approved next steps include asking your doctor to check calcium, PTH, vitamin D, and kidney function, then considering an endocrinology referral, imaging only after abnormal labs, and treatment such as curative parathyroid surgery for hyperparathyroidism or calcium plus active vitamin D for hypoparathyroidism; seek urgent care for chest pain, severe spasms, confusion, or palpitations, and review the important details below that could shape your next steps.

Q.
Unexplained Fatigue? Why Your Calcium Is High & Medically Approved Next Steps
A.
Unexplained fatigue with a high calcium level usually means hypercalcemia, most often from primary hyperparathyroidism, though medications or supplements, kidney or thyroid issues, prolonged immobility, and less commonly cancer can also be responsible. There are several factors to consider, and the right next steps can change based on details like your PTH, corrected or ionized calcium, and kidney function; confirm the result, review meds and vitamin D or calcium intake, and seek urgent care for severe symptoms such as confusion, vomiting that will not stop, chest pain, or an irregular heartbeat. See the complete guidance below.
