The Disease That Hides in Plain Sight
Hyperparathyroidism is one of the most common endocrine disorders in adults, yet it is frequently diagnosed only after years of unexplained symptoms, or discovered purely by accident on a routine blood test.
The reason it goes undetected for so long is that hyperparathyroidism symptoms are often nonspecific. Fatigue, bone aches, mental fog, constipation, and mood changes are common complaints that get attributed to aging, stress, or a dozen other conditions. But when those symptoms are accompanied by persistently elevated calcium on blood work, the parathyroid glands are often the culprit.

13 Hyperparathyroidism Symptoms Patients Most Commonly Report
Parathyroid disease affects almost every system in the body because calcium plays a fundamental role in nerve function, muscle contraction, bone density, and kidney health. Here are the most commonly reported symptoms:
- Persistent, unexplained fatigue, described by patients as “bone tired”
- Difficulty concentrating or “brain fog”
- Depression, anxiety, or irritability
- Bone or joint pain, especially in the hips, back, or legs
- Kidney stones, especially recurrent episodes
- Osteoporosis or low bone mineral density
- Frequent urination or excessive thirst
- Muscle weakness
- Nausea, poor appetite, or constipation
- Abdominal discomfort
- High blood pressure
- Irregular heartbeat (in severe cases)
- General sense of feeling unwell without a clear cause
It is common for patients to have 5 or more of these symptoms for years before the diagnosis is made.
How the Diagnosis Is Made
Diagnosis requires a simple blood test. The combination of elevated serum calcium AND elevated (or inappropriately high normal) parathyroid hormone (PTH) is essentially diagnostic of primary hyperparathyroidism. Additional tests may include:
- 24-hour urine calcium to rule out familial hypocalciuric hypercalcemia (a benign inherited condition that does not require surgery)
- DEXA scan (bone density scan) to assess osteoporosis severity
- Kidney function tests and renal imaging
- Sestamibi parathyroid scan and/or neck ultrasound to localize the overactive gland before surgery
The Only Cure: Parathyroid Surgery
Minimally invasive parathyroidectomy (the removal of the overactive parathyroid gland) is the only definitive treatment for primary hyperparathyroidism. It has a cure rate above 95% and a complication rate below 2% in experienced surgical hands.
Dr. Neychev performs targeted, minimally invasive parathyroid surgery. The procedure involves a small incision (less than one inch) in the neck, typically takes under 90 minutes, and allows most patients to go home the same day. Intraoperative PTH monitoring is used to confirm that the overactive gland has been completely removed before the incision is closed.
What Patients Experience After Surgery
The symptom improvement after successful parathyroid surgery can be dramatic. Within days to weeks, most patients report:
- Significantly improved energy levels
- Clearer thinking and better concentration
- Improved mood
- Reduction in bone pain
- Stabilization or improvement in bone density over 1–2 years
- No further kidney stone formation (in most patients)

Frequently Asked Questions
Medications like cinacalcet can lower calcium levels temporarily but do not cure the disease. Surgery is the only treatment that removes the tumor and resolves the hormonal imbalance permanently.
Most cases of primary hyperparathyroidism are sporadic (not inherited). However, it can be part of hereditary syndromes such as Familial hypocalciuric hypercalcemia, Multiple Endocrine Neoplasia Type 1 (MEN1) or MEN2A, particularly in younger patients or those with multiple affected glands.
About 5–15% of cases involve enlargement of more than one parathyroid gland. In these cases, a more extensive exploration of all four glands may be necessary. Dr. Neychev has specific training in multi-gland disease from his NIH fellowship.
Calcium levels normalize within days. Energy, mood, and cognitive symptoms often improve within weeks. Bone density improvement takes 1–2 years of follow-up to fully appreciate on DEXA scans.
Monitoring is appropriate for some patients, particularly older patients with very mild disease. However, current guidelines are generally favorable toward surgery because the cure rate is high, the procedure is low-risk, and long-term complications of untreated hyperparathyroidism (osteoporosis, kidney stones) accumulate over time. A second surgical opinion is always reasonable.
