Hi,
Noted the history related to your husband having an incidence of coughing followed by
unconsciousness and foam by nose and mouth, disoriented after coming out of it. He was drinking at that time and not eating, happened for the first time.
The most probable cause I can think about is one of the following:
Epilepsy like fit.
Laryngospasm meaning the closure of airway part called
larynx or over-approximation of vocal cords.
Any neurological problem.
Hence I would advise you the following in such a situation:
Consult the Doctor immediately or rush to ER for clinical evaluation an relevant investigations like:
CT scan of brain.
EEG that is electroencephalogram.
Tests of blood.
Neurologist's opinion and further management.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, ENT & General Surgeon
