[Vocabulary] to be clogged

[englishhobby]

Is the above phrase used by native speakers to talk about people's health? (I found it in the vocabulary list for the topic). As far as I can guess, it has something to do with nasal conjestion. (There is one more idea, but I am afraid it wouldn't be very decent to word it here).
If my second guess is right - I don't think it is a good idea to use it when teaching students "health" vocabulary. Am I right?:?:

Your arteries may be clogged, but you would not say, "I am clocgged". Your nose is more likely to be stuffed up or congested than clogged. If you are unable to make a bowel movement, you are constipated.
