Hyperparathyroidism

Hyperparathyroidism: Understanding, Diagnosing, and Treating Parathyroid Hormone Imbalance

Hyperparathyroidism is a hormonal disorder that occurs when the parathyroid glands produce too much parathyroid hormone (PTH). These small glands, located behind the thyroid, regulate calcium and phosphorus levels in the body. When they become overactive, blood calcium levels rise—leading to bone loss, kidney stones, and other complications. Many patients go undiagnosed until routine blood work reveals elevated calcium.

At Thyroid Doctor Miami, we specialize in identifying and managing conditions like hyperparathyroidism. With early diagnosis and effective treatment, patients can restore balance and prevent long-term complications affecting bone, kidney, and cardiovascular health.

What Is Hyperparathyroidism?

Hyperparathyroidism occurs when one or more parathyroid glands secrete excess PTH, disrupting the balance of calcium and phosphorus.

Types of Hyperparathyroidism:

Primary Hyperparathyroidism: Caused by an abnormality within the parathyroid glands themselves, such as a benign tumor (parathyroid adenoma), hyperplasia, or rarely parathyroid cancer.
Secondary Hyperparathyroidism: Results from chronic conditions like kidney disease or vitamin D deficiency, which cause prolonged low calcium and overstimulation of the parathyroid glands.
Tertiary Hyperparathyroidism: Often seen in patients with long-term kidney disease, when the glands remain overactive even after the underlying cause has been addressed.

At Thyroid Doctor Miami, we determine the type of hyperparathyroidism to guide the best treatment strategy.

Causes and Risk Factors

Hyperparathyroidism arises from a mix of genetic, medical, and lifestyle factors.

Common Causes of Primary Hyperparathyroidism:

Parathyroid adenoma (benign tumor of one gland)
Hyperplasia (overgrowth of multiple glands)
Rarely, parathyroid carcinoma

Risk Factors Include:

Age over 50
Female sex (women are at higher risk)
Family history of parathyroid disease or MEN syndromes (multiple endocrine neoplasia)
Long-term lithium therapy
Chronic kidney disease or vitamin D deficiency (for secondary cases)

Patients with unexplained high calcium should always be evaluated for hyperparathyroidism.

Symptoms of Hyperparathyroidism

Symptoms may be subtle at first but progress as calcium levels rise.

Common Symptoms:

Fatigue and weakness
Bone pain and frequent fractures (osteoporosis, osteopenia)
Kidney stones or frequent urination
Abdominal pain, nausea, or constipation
Depression, irritability, or memory issues
Muscle cramps and joint aches
High blood pressure or cardiovascular problems

The classic phrase “bones, stones, groans, and psychiatric overtones” reflects the common ways this condition affects the body.

Diagnosis and Testing

Hyperparathyroidism is often discovered through blood work and confirmed with specialized tests.

Initial Screening:

Serum Calcium: Elevated in most cases
Parathyroid Hormone (PTH): Elevated or inappropriately normal despite high calcium
Vitamin D levels: To assess deficiency and rule out secondary causes

Confirmatory Testing:

24-Hour Urinary Calcium: Helps distinguish between familial hypocalciuric hypercalcemia (FHH) and hyperparathyroidism
Bone Density Scan (DEXA): Measures bone strength and fracture risk

Imaging Studies:

Neck Ultrasound or Sestamibi Scan: Localizes abnormal parathyroid glands before surgery
4D CT or MRI: Advanced imaging in complex cases

At Thyroid Doctor Miami, we combine lab evaluation with expert imaging to deliver an accurate diagnosis.

How Hyperparathyroidism Affects the Body

Persistent high calcium and PTH levels can damage multiple organ systems.

Potential Complications:

Skeletal Issues: Osteoporosis, osteopenia, and increased fracture risk
Kidney Damage: Kidney stones, nephrocalcinosis, or chronic kidney disease
Cardiovascular Disease: Hypertension, arrhythmias, and vascular calcification
Neurocognitive Symptoms: Fatigue, depression, and difficulty concentrating
Gastrointestinal Symptoms: Peptic ulcers or pancreatitis in severe cases

Because parathyroid and thyroid function are closely linked, both must be carefully evaluated in patients with hormone imbalances.

Treatment and Management

Treatment depends on whether the hyperparathyroidism is primary, secondary, or tertiary.

Lifestyle and Monitoring

Adequate hydration to reduce kidney stone risk
Moderate calcium and vitamin D intake
Regular exercise to support bone strength
Routine monitoring of calcium, kidney function, and bone density

Medications

Calcimimetics (Cinacalcet): Reduce PTH production in certain cases
Bisphosphonates or Denosumab: Help protect bone density
Vitamin D supplements: For secondary hyperparathyroidism due to deficiency

Surgery

Parathyroidectomy (surgical removal of abnormal glands): The only cure for primary hyperparathyroidism
Typically performed when calcium is very high, bones or kidneys are affected, or the patient is under 50 years old
Minimally invasive surgery is often possible with excellent long-term results

At Thyroid Doctor Miami, we provide advanced endocrine surgery options alongside medical management for optimal outcomes.

Hyperparathyroidism and Thyroid Health

Thyroid and parathyroid conditions often overlap. Thyroid surgery can sometimes affect the parathyroid glands, while untreated hyperparathyroidism may worsen bone loss in patients with thyroid disorders. At Thyroid Doctor Miami, our integrated approach ensures both glands are evaluated and treated together for comprehensive endocrine care.

Take Control of Your Hormonal Health

If you’ve been struggling with high calcium, kidney stones, bone loss, or unexplained fatigue, hyperparathyroidism may be the cause. Early diagnosis and treatment can restore balance and prevent long-term damage.

Can Thyroid Cancer Be Cured?

Yes—especially when detected early. Papillary and follicular thyroid cancers have survival rates above 95%. Even advanced or medullary thyroid cancers can often be managed with skilled treatment.

Early detection, precise surgery, and long-term monitoring are key to lasting remission.
