Frequent convulsions, which can be seizures, can also be seen in patients with low blood calcium. In the case of seizures, there are several clinical types, including tonic-clonic seizures, tonic seizures, and myoclonic and atonic seizures. If the patient has convulsions, tonic-clonic seizures are usually mostly recommended, and the patient may also have double eye suspension, foaming at the mouth, and in severe cases, the patient may also become unconscious. If the patient has more than 2 seizures, the main treatment is to apply antiepileptic drugs. If hypocalcemia is considered to be the cause, patients generally show hand and foot convulsions, most of them do not have consciousness disorder, the patient’s blood electrolytes should be monitored in time, severe hypocalcemia may cause cardiac arrest, and should be corrected in time.
