False. I've worked in a hospital. They keep you in the hospital overnight for a lot of simple reasons. They kept me overnight once just because my BP was a little high. Some people on this site are absolute idiots and very embarrassing.Posts like this are just bs. The guy is in the hospital, so it is not something minor. Hopefully he gets out and is fine, but they don't keep you in the hospital for minor things. Some of you may think that anxiety attacks are stress related blood pressure issues are minor things, but they are not. If they hold you overnight in a hospital, it is generally because they think you could possibly die if you were not at the hospital.
