Hypercalcemia
Causes
What causes Hypercalcemia?
Several factors can contribute to high calcium levels in the blood. These include:
- Hyperparathyroidism: Overactive parathyroid glands can lead to increased calcium absorption from the bones.
- Cancer: Certain types of cancer, such as lung cancer, breast cancer, and multiple myeloma, can cause calcium to be released into the bloodstream.
- Medications: Some medications, including diuretics, lithium, and calcium supplements, can disrupt calcium balance.
- Hormonal imbalances: Disorders such as thyroid disorders and adrenal gland disorders can affect calcium regulation.
- Vitamin D toxicity: Excessive intake of vitamin D supplements can lead to hypercalcemia.
- Immobility: Prolonged bed rest or immobility can cause calcium to leach from the bones.
Symptoms
What are the signs and symptoms of Hypercalcemia?
Hypercalcemia symptoms can vary depending on the severity of the condition and how rapidly calcium levels rise. Common symptoms may include:
- Fatigue and weakness
- Nausea, vomiting, and loss of appetite
- Excessive thirst and frequent urination
- Abdominal pain or constipation
- Bone pain or muscle weakness
- Confusion or cognitive changes
- Irregular heartbeat or heart palpitations
- Kidney stones or renal complications

Treatment
How is Hypercalcemia Treated?
In addition to hydration therapy, various medications may be prescribed to manage hypercalcemia. Bisphosphonates, calcitonin, and corticosteroids are commonly used to inhibit bone resorption and lower calcium levels. These medications work by slowing down the breakdown of bone tissue, thereby reducing the release of calcium into the bloodstream.
In cases where hypercalcemia is caused by hyperparathyroidism, surgical intervention may be necessary. Parathyroid surgery involves the removal of the overactive parathyroid gland responsible for excessive production of parathyroid hormone (PTH). By removing the abnormal gland, normal calcium regulation can be restored.
Furthermore, lifestyle modifications may play a crucial role in managing hypercalcemia. Dietary changes, such as reducing calcium intake and avoiding vitamin D supplements, may be recommended to prevent further increases in blood calcium levels. Patients are encouraged to work closely with healthcare providers to develop a comprehensive treatment plan tailored to their individual needs and underlying medical conditions.
