As nausea worsens, you will eventually have a strong urge to vomit. As mentioned, when the body recognizes the presence of a foreign pathogen, as in the case of an infected appendix, it will attempt to purge itself an in effort to remove the pathogen. The vomiting associated with appendicitis is likely to be severe.
It can also worsen other symptoms of this condition. If you are vomiting profusely, pay attention to your body and take note of any other symptoms that are indicative of appendicitis. If you notice any other symptoms, head to the doctor or a hospital immediately.
