Parathyroid Disorders: Diagnosis & Treatment of Calcium Imbalance
A clear guide to parathyroid disorders, conditions affecting the glands that regulate calcium, causing calcium levels to become too high or too low.
Treatment usually begins with
Calcium & PTH Testing
Imaging
Specialist Consultation
Targeted Treatment
Evaluation with calcium and parathyroid hormone testing identifies the specific cause, guiding either medication, monitoring or surgical treatment.
You may need this evaluated if...
Evaluation for a parathyroid disorder is recommended when these signs appear:
- Fatigue, bone pain or kidney stones with abnormal calcium levels
- Muscle cramps, tingling or numbness
- Unexplained high or low calcium found on routine blood tests
- A history of neck surgery with new symptoms
Parathyroid disorders are very treatable once identified, with medication, monitoring or a straightforward surgical procedure resolving most cases.
What is Parathyroid Disorders & Calcium Imbalance?
The parathyroid glands regulate calcium levels in the blood, and parathyroid disorders occur when they produce too much or too little hormone, affecting bone health, kidney function and muscle and nerve activity.
Often Found on Routine Blood Tests
Many cases are first identified when a routine blood test shows abnormal calcium levels.
Bone and Kidney Health Are Linked
Untreated parathyroid disorders can affect both bone strength and kidney stone risk.
Surgery Is Often Curative
For overactive parathyroid glands, removing the affected gland typically resolves the problem completely.
Underactive Disease Is Managed Long-Term
Low parathyroid hormone is managed with ongoing calcium and vitamin D supplementation.
Common Symptoms
- Fatigue and muscle weakness
- Bone pain or increased fracture risk
- Kidney stones
- Muscle cramps, tingling or numbness (with low calcium)
- Digestive symptoms such as constipation (with high calcium)
What Increases Your Risk
A combination of genetic, hormonal and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Calcium & Parathyroid Hormone (PTH) Blood Tests
Confirms the diagnosis and identifies the pattern of imbalance.
Vitamin D Testing
Assesses a contributing or related factor in calcium regulation.
Imaging (Ultrasound/Sestamibi Scan)
Localises an overactive parathyroid gland before surgery.
Bone Density Testing
Assesses the impact of long-standing calcium imbalance on bone health.
Treatment Approaches
Medical & Hormonal Management
- Calcium and vitamin D supplementation for underactive parathyroid disease
- Monitoring for mild, asymptomatic overactive parathyroid disease
- Medication to manage calcium levels in select cases
- Hydration and dietary guidance to reduce kidney stone risk
Advanced & Procedural Care
Surgical removal of the overactive parathyroid gland is the definitive treatment for significant or symptomatic overactive parathyroid disease.
Treatment decisions are based on hormone levels, imaging and your overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly helps protect your long-term hormonal and metabolic health.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- Mildly abnormal calcium levels found on a routine blood test
Seek Urgent Care
Reach out for emergency care immediately if you notice any of the following.
- Severe muscle cramps, seizures, or an irregular heartbeat linked to calcium imbalance
