Hypocalcemia is a medical condition characterized by low levels of calcium in the blood. Calcium is essential for many bodily functions, including bone health, muscle contractions, and nerve signaling. When calcium levels drop too low, it can lead to various health issues.
Pathophysiology
Structure:
Calcium is a vital mineral found in bones, teeth, and blood. It is stored in bones and released into the bloodstream as needed.
Blood Supply:
Calcium is present in two forms in the blood: free (ionized) calcium, which is active and used by the body, and bound calcium, which is attached to proteins. The balance between these forms is crucial for maintaining normal calcium levels.
Nerve Supply:
Calcium plays a key role in the nervous system. It helps transmit signals between nerves and muscles, allowing for proper movement and function.
Types of Hypocalcemia
- Acute Hypocalcemia: A sudden drop in calcium levels, often leading to severe symptoms.
- Chronic Hypocalcemia: A long-term condition where calcium levels remain consistently low.
- Symptomatic Hypocalcemia: Hypocalcemia accompanied by noticeable symptoms.
- Asymptomatic Hypocalcemia: Low calcium levels without any symptoms.
Causes of Hypocalcemia
Here are 20 potential causes of hypocalcemia:
- Hypoparathyroidism: Decreased production of parathyroid hormone.
