1. Hypercalcemia: This condition is characterized by elevated levels of calcium in the blood. It can result from various causes, including:
   - Hyperparathyroidism (overactivity of the parathyroid glands)
   - Malignancies (certain cancers can cause increased calcium release from bones)
   - Vitamin D intoxication
   - Sarcoidosis and other granulomatous diseases

2. Hypocalcemia: This condition involves low levels of calcium in the blood and can be caused by:
   - Hypoparathyroidism (underactivity of the parathyroid glands)
   - Vitamin D deficiency or malabsorption
   - Chronic kidney disease
   - Certain medications that affect calcium absorption or metabolism

Symptoms

The symptoms of calcium metabolism disorders can vary widely depending on whether the individual is experiencing hypercalcemia or hypocalcemia:

Overview of Calcium Metabolism Disorders

Calcium plays a vital role in numerous physiological processes, including bone health, muscle function, nerve transmission, and blood coagulation. Disorders of calcium metabolism can lead to significant health issues, including osteoporosis, cardiovascular problems, and neuromuscular dysfunction. The treatment strategies for these disorders typically focus on correcting the underlying cause, restoring normal calcium levels, and managing symptoms.

Treatment Approaches

1. Management of Hypocalcemia

Hypocalcemia, characterized by low calcium levels in the blood, can result from various factors, including vitamin D deficiency, hypoparathyroidism, and chronic kidney disease. Treatment strategies include:

• Calcium Supplementation: Oral calcium supplements (e.g., calcium carbonate or calcium citrate) are commonly prescribed to increase calcium levels. In severe cases, intravenous calcium may be necessary[1].

• Vitamin D Supplementation: Since vitamin D is crucial for calcium absorption, supplementation with vitamin D (ergocalciferol or cholecalciferol) is often recommended to enhance calcium uptake from the gut[1].

• Hormonal Therapy: In cases of hypoparathyroidism, recombinant human parathyroid hormone (rhPTH) may be used to help regulate calcium levels[1].

2. Management of Hypercalcemia

Hypercalcemia, or elevated calcium levels, can be caused by conditions such as hyperparathyroidism, malignancies, or excessive vitamin D intake. Treatment options include:

• Hydration and Diuretics: Intravenous fluids are administered to promote renal excretion of calcium. Loop diuretics may also be used to enhance calcium excretion[1].

• Bisphosphonates: Medications like zoledronic acid or pamidronate are effective in treating hypercalcemia, particularly when associated with malignancy, as they inhibit bone resorption[1].

• Calcitonin: This hormone can be administered to lower calcium levels by inhibiting osteoclast activity, although its effects are typically short-lived[1].

• Corticosteroids: In cases where hypercalcemia is due to granulomatous diseases (e.g., sarcoidosis), corticosteroids can help reduce calcium levels by decreasing intestinal absorption and increasing renal excretion[1].

3. Dietary Modifications

Dietary adjustments play a significant role in managing calcium metabolism disorders. For hypocalcemia, increasing dietary calcium intake through dairy products, leafy greens, and fortified foods is beneficial. Conversely, for hypercalcemia, reducing dietary calcium and avoiding excessive vitamin D intake is advised[1].

4. Monitoring and Follow-Up

Regular monitoring of serum calcium levels, renal function, and parathyroid hormone levels is essential for patients with calcium metabolism disorders. This helps in adjusting treatment plans and ensuring effective management of the condition[1].
