Kalziumwert

The term *Kalziumwert* refers to the concentration of calcium (Calcium) in the blood, typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Calcium is an essential mineral that plays a crucial role in various physiological processes, including bone formation, nerve function, muscle contraction, and blood clotting. Maintaining balanced calcium levels is vital for overall health.

Calcium levels in the blood are regulated primarily by hormones such as parathyroid hormone (PTH), calcitriol (the active form of vitamin D), and calcitonin. The *Kalziumwert* can be influenced by dietary intake, absorption in the gut, renal excretion, and bone metabolism. Abnormal calcium levels, whether too high (hypercalcemia) or too low (hypocalcemia), can indicate underlying medical conditions.

A normal *Kalziumwert* in adults typically ranges between 8.5 and 10.5 mg/dL (2.1–2.6 mmol/L). Blood tests are commonly used to measure calcium levels, often as part of a comprehensive metabolic panel. Factors such as age, sex, and overall health may slightly alter reference ranges, so medical interpretation is essential.

Hypercalcemia, characterized by elevated calcium levels, may result from conditions like hyperparathyroidism, certain cancers, or excessive vitamin D intake. Symptoms can include fatigue, kidney stones, nausea, or confusion. Hypocalcemia, with low calcium levels, may occur due to vitamin D deficiency, hypoparathyroidism, or chronic kidney disease, leading to muscle cramps, tingling sensations, or seizures.

Dietary sources of calcium, such as dairy products, leafy greens, nuts, and fortified foods, help maintain adequate levels. In some cases, supplementation may be necessary under medical supervision. Regular monitoring and consultation with a healthcare provider are recommended for individuals with known calcium imbalances or risk factors.
