Symptoms and main manifestations of hypocalcemia are increased neuromuscular excitability, numbness and tingling at the ends of the fingers or mouth, muscle spasms of the hands, feet and face, and in severe cases, convulsions of the hands and feet, and the fingers are in the form of eagle’s claw, such as epileptic seizures. Children may have convulsions or epileptiform generalized convulsions, which are often misdiagnosed as grand mal seizures if not accompanied by hand and foot twitching.
Chronic hypocalcemia may also present with psychiatric symptoms such as irritability, agitation, depression, or psychosis. Children often have delayed physical and mental development and impaired dental development.
In clinical work, serum calcium below 2.2 mmol/L is called hypocalcemia. If patients have symptoms of hypocalcemia, they should go to regular hospitals in time and take vitamin D and calcium supplements under the guidance of professional doctors to avoid delays.
