10 Calcium Deficiency Symptoms
Reviewed: Dr. Mera
Symptom #3: Tetany
Tetany occurs when there is involuntary contraction of the muscles due to disorders that increase the action potential frequency of nerves or muscle cells. It is generally characterized by the contraction of the distal muscles of the hands and feet. This is known as carpopedal spasm.
In the hands, the carpal spasm results in flexion of the metacarpophalangeal joints and extension of interphalangeal joints. Tetany can be associated with perioral and distal limb tingling. Some causes of tetany include calcium deficiency, low carbon dioxide levels, low magnesium levels, excess potassium levels, and clostridium tetani toxin.
