I m an 18 yr old female, roughly 125lb and 5 4 . I often randomly throw up for no reason. I can be sitting watching t.v. and I get the urge to throw up. I don t feel nauseous at all, but my mouth does start watering. I also throw up a lot if I laugh, or cough too hard. Or swallowing food. But I ve been told that s probly from sensitive larynx. idk. My big question is then, why do I throw up so much for no reason, with no warning, when I didn t eat anything out of the ordinary, i m not nervous etc... Its been going on for at least 4 years now
