I'm in treatment for anorexia, i've had severe unexplained nausea & vomiting for days, zofran dissolving tabs aren't helping. what can i do?

Requires med checkup: Nausea and vomiting, if they persist are indicative of something serious going on in your body. To find the cause, you should visit your doctor and get a check up. He/she will check your body especially your stomach and abdominal organs such as liver. Besides physical examination, blood tests such as liver functions and kidney function need to be tested. Upper endoscopy may also need to be done.
