What is Nausea and Vomiting?


If you are experiencing nausea and vomiting, it’s important to visit a doctor. Your provider will want to know your symptoms and what you’re doing or eating to determine the cause. They may recommend a brain scan to rule out other conditions causing your symptoms. If you’re a woman of childbearing age, they’ll also want to check your pregnancy status.


Symptoms of nausea are common among many medical conditions, including stomach flu and food poisoning. Abdominal cramps and diarrhoea often accompany them.

There are several causes of nausea, from viral infection to the effects of medications. It may also be due to pregnancy, seasickness, or disease of the oesophagus or brain.
