In 1882, Dr. Samuel Gee first noticed the syndrome in children 4 to 8 years old, and for years afterward it was thought to primarily affect children, but recent research shows that it may be just as common among adults.

In one study of 41 adults, 16 patients had surgery to try to cure their vomiting episodes, and it wasn’t effective in a single case.
