What is Hypercalcemia?
Calcium plays a crucial role in maintaining the strength and structure of bones and teeth, facilitating muscle contractions, and ensuring proper nerve function. The normal range for calcium levels in the blood is between 8.5 and 10.2 mg/dL. Hypercalcemia occurs when these levels exceed the upper limit of this range.
Causes of Hypercalcemia
Several factors can contribute to the development of hypercalcemia, including:
- Hyperparathyroidism: This is the most common cause of hypercalcemia. It occurs when one or more of the parathyroid glands produce too much parathyroid hormone (PTH), leading to an increase in calcium levels.
- Cancer: Certain cancers, particularly lung, breast, and multiple myeloma, can cause hypercalcemia. Cancer cells can produce proteins that act like PTH or invade bones, releasing calcium into the bloodstream.
- Medications: Some medications, such as lithium and thiazide diuretics, can increase calcium levels. Overuse of calcium or vitamin D supplements can also contribute.
- Other Medical Conditions: Conditions such as tuberculosis and sarcoidosis can cause granulomas that produce vitamin D, leading to increased calcium absorption.
- Dehydration: Severe dehydration can lead to increased concentration of calcium in the blood due to reduced fluid levels.
- Genetic Factors: Familial hypocalciuric hypercalcemia is a rare genetic disorder that causes elevated blood calcium levels.
Symptoms of Hypercalcemia
The symptoms of hypercalcemia can vary depending on the severity and rate of increase in calcium levels. Mild hypercalcemia may be asymptomatic or cause non-specific symptoms such as:
- Fatigue
- Weakness
- Nausea
- Constipation
- Frequent urination
Moderate to severe hypercalcemia can lead to more pronounced symptoms, including:
- Abdominal pain
- Vomiting
- Dehydration
- Confusion
- Depression
- Bone pain
- Muscle weakness
- Arrhythmias (irregular heartbeats)
- Kidney stones or kidney failure
Diagnosis
Diagnosing hypercalcemia typically involves:
- Blood Tests: Measuring total calcium and ionized calcium levels in the blood.
- PTH Levels: Assessing parathyroid hormone levels to determine if hyperparathyroidism is the cause.
- Vitamin D Levels: Checking for vitamin D intoxication or deficiency.
- Imaging Tests: Bone density scans, X-rays, or CT scans to identify underlying causes such as tumors or granulomas.
Treatment
The treatment of hypercalcemia depends on its severity and underlying cause:
- Hydration: Increasing fluid intake, often intravenously, to help dilute calcium levels and promote excretion through the kidneys.
- Medications:
- Bisphosphonates: These drugs, such as pamidronate or zoledronic acid, inhibit bone resorption.
- Calcitonin: Helps lower calcium levels by inhibiting bone resorption and increasing calcium excretion in the kidneys.
- Steroids: Useful in cases caused by granulomatous diseases like sarcoidosis.
- Dialysis: In severe cases, particularly when kidney function is impaired, dialysis may be necessary to remove excess calcium.
- Surgery: For hyperparathyroidism, surgical removal of the overactive parathyroid gland(s) is often required.
Preventing Hypercalcemia
Prevention strategies include:
- Regular monitoring of calcium and PTH levels, especially in individuals with known risk factors.
- Avoiding excessive use of calcium and vitamin D supplements without medical supervision.
- Staying hydrated, particularly in situations where dehydration is likely.
Conclusion
Hypercalcemia is a condition that requires prompt diagnosis and appropriate treatment to prevent serious health complications. Understanding the causes, recognizing the symptoms, and seeking timely medical intervention can help manage this condition effectively. If you suspect you have hypercalcemia or are at risk, consult with a healthcare professional for a thorough evaluation and personalized management plan.
