The main cause of foaming at the mouth is the frothy change that occurs during outward ventilation of the lungs due to the inability of oral and nasal secretions to effectively enter the lungs and digestive tract. These disorders are most commonly associated with epilepsy, in which the normal swallowing function is inhibited, secretions are not excreted downward, and there is an exuberant secretion from the glands, which leads to an increase in secretions from the oral cavity and the respiratory tract, and an increase in the airflow of the lungs during the seizure, which can easily lead to similar symptoms, and it is recommended that an electroencephalogram (EEG) be performed to assist in the diagnosis. If the seizure is acute, the patient needs to be protected during the acute seizure to avoid choking and serious injury to the tongue.
