In patients with hypoparathyroidism, which electrolyte imbalance is typically observed?

• A. Hypocalcemia
• B. Hypercalcemia
• C. Hyperphosphatemia
• D. Hyponatremia

Answer: (A)

Hypoparathyroidism is characterized by an insufficient production of parathyroid hormone (PTH), which plays a crucial role in regulating calcium and phosphorus levels in the body. In patients with this condition, the lack of PTH leads to decreased calcium reabsorption from the bones, reduced intestinal absorption of calcium, and impaired renal reabsorption of calcium. Consequently, these mechanisms result in lower serum calcium levels, known as hypocalcemia. Hypocalcemia is the key electrolyte imbalance associated with hypoparathyroidism. Patients may exhibit symptoms such as tetany, muscle cramps, and tingling sensations due to low calcium levels, which can affect neuromuscular excitability. It is important to note that, in conjunction with hypocalcemia, patients may experience elevated phosphate levels (hyperphosphatemia), as PTH normally facilitates the excretion of phosphate. However, the primary hallmark of hypoparathyroidism is indeed hypocalcemia. Understanding this imbalance is essential for clinical management and highlights the importance of monitoring calcium levels in patients diagnosed with hypoparathyroidism.
