Nausea and Vomiting/how often does the average person vomit


When I was a child I vomited about once a year, & I`m wondering if that`s excessive, also, I`m wondering how often do adults vomit on average. I haven`t vomited for almost 16 years, how do I compare with the average person?

According to surveys I've done for my Vomiting FAQ, people can be classed into four vomit types.  I haven't researched children, so these are all based on adults.

1.  33% of people vomit on three or more days a year, and they are called PROLIFIC VOMITERS.

2.  40% of people vomit on one or two days a year, and they are called REGULAR VOMITERS.

3.  25% of people vomit less than once a year, but at least once in five years, and they are called INFREQUENT VOMITERS.

4.  2% of people vomit less than once in five years.  They are called NON-VOMITERS.

You seem to be a non-vomiter, like me.  Good show!

I will try to answer all questions about nausea, vomiting, and emetophobia. I know many ways of preventing vomiting (or bringing it on). I have not vomited in over 40 years.


For over 19 years, I have answered questions about nausea, vomiting, and emetophobia on the internet. I wrote the Emetophobia FAQ (Frequently Asked Questions About Emetophobia) and the Vomiting FAQ (Frequently Asked Questions About Vomiting). I wrote the first website about emetophobia and started the first mailing list about emetophobia. Both are still in existence. I am moderator of the largest emetophobia site.

I have a bachelors degree in computer science. I have studied nausea, vomiting, and emetophobia for over 30 years and have read many scientific articles about everything from morning sickness to space sickness.
