Why do people foam at the mouth after death?

Generally speaking, it can be divided into gastrointestinal vomiting type and nerve spasm type, gastrointestinal vomiting: caused by gastrointestinal spasms or excessive gastric acid, nerve spasm: because of nervous convulsions, such as; Epilepsy, poisoning, etc., make the nerves unable to control the upper respiratory muscles and gastrointestinal muscles, resulting in unintentional spasms of the upper qi and food systems, resulting in foaming at the mouth and vomiting gastric juice, but there will be other causes for specific diseases, such as:

Stupidity leads to the inability to control the facial muscles, and excessive saliva secretion caused by nerve problems, etc., can lead to foaming at the mouth.

It is possible that the temperature is too high and there is a bit of heat stroke.

Foaming at the mouth refers to the foaming of saliva coming out of the mouth, which is usually seen in organophosphate poisoning and in patients with epilepsy, and "foaming at the mouth" is organophosphate poisoning, because organophosphate poisoning inhibits the sympathetic nerves. Causes the pupils to constrict, the trachea to constrict, and excessive saliva production. When you breathe, you salivate a lot, and it looks like you're "foaming at the mouth".

However, it can also be caused by seizures.

During diagnosis, the patient's pupil size, breathing, and consciousness should be observed to determine what caused the foaming at the mouth. Foaming at the mouth during poisoning should be distinguished from seizures. Epilepsy is generally dizziness, confusion, epigastric discomfort, and audio-visual and olfactory disturbances.

During the attack (spasmodic seizure period), some patients first make a sharp scream, and then have both loss of consciousness and fall, there is muscle rigidity of the whole body, breathing pause, the head and eyes can be deviated to one side, and after a few seconds, there are clonic convulsions, the convulsions gradually worsen, which lasts for dozens of seconds, and the breathing resumes during the clonic period, and the mouth foams. Foaming at the mouth during poisoning should be distinguished from seizures.

Epilepsy is generally dizziness, confusion, epigastric discomfort, and audio-visual and olfactory disturbances. During the seizure (spasmodic seizure period), some patients first make a high-pitched scream, and then have both loss of consciousness and fall, the whole body muscle rigidity, respiratory arrest, the head and eyes can be tilted to one side, a few seconds later there are clonic convulsions, the convulsions gradually worsen, lasting a few seconds, the clonic phase of breathing resumes, foaming at the mouth.

This condition can be seen in diseases such as cerebral hemorrhage caused by hypertension, hypertensive encephalopathy, organophosphate pesticide poisoning, acute pulmonary embolism, and sudden cardiac death.

Opinion suggestion: Since it is known that the patient has hypertension before, the first two are more likely, if it is organophosphorus pesticide poisoning, this can be identified from the smell, and the rest can only be verified by autopsy.

I had an oxygen infusion process before my death, may heaven be free from sickness.

Because, that man drank too much soap and water!

Because he couldn't vomit anything else, he had to foam at the mouth.
