Additionally, laryngospasms can result from hypocalcemia, causing muscle spasms and/or tetany. Severe symptoms include arrhythmias, seizures, or tetany. This explains muscle flaccidity rather than tetany following fasciculations. Symptoms include neuromuscular excitability, which potentially causes tetany and disruption of conductivity in cardiac tissue. Hypocalcemia symptoms include parathesias, myalgias, muscle cramping, tetany, and convulsions. Also, it can cause metabolic alkalosis (with signs including muscular twitchings, irritability and tetany). Common symptoms include muscle weakness, cramps, stiffness, and tetany. Patients can have pain secondary to uterine contractions, uterine tetany or localized uterine tenderness. Hypoparathyroidism leads to hypocalcaemia, evidenced by tetany seizure and respiratory paralysis. More severe symptoms such as seizures, tetany, and paralysis have been reported. They had poor balance and tetany, or muscle spasms, in the claws. Affected people usually present with hypocalcaemia, tetany, or afebrile convulsions at any age. Trousseau sign of latent tetany is a medical sign observed in patients with low calcium. Symptoms included swooning, moaning, chattering of teeth, hyperpnea, and tetany. If severe, it may cause tetany.
