6. Swallowing the Tongue
Another way in which a seizure can cause a kind of secondary dangerous health problem is if it causes the individual to swallow their tongue. For obvious reasons, this can be highly dangerous as the tongue lolls into the back of the throat and potentially blocks the windpipes.
If you want to prevent this from happening to someone you know or witness, then one of the best things you can do to help is to get them into the recovery position. This is designed to help them prevent injuring themselves as a result of contractions and writhing, and at the same time, it can also help them to avoid swallowing their tongue.
