10 Symptoms of Hypoparathyroidism
Symptom #2: Tetany
Tetany is a medical sign where there is involuntary contraction of muscles which is due to conditions where the action potential frequency of nerves or muscle cells are increased. In hypoparathyroidism, tetany is usually caused by hypocalcemia which is the primary cause of tetany.
The low calcium levels in the extracellular fluid causes increased excitability of the neurons, resulting in muscle spasms that lead to tetanus. Besides hypocalcemia, tetany can also occur in low levels of carbon dioxide such as hyperventilation, low levels of magnesium, and more.
