In some instances, we will need to run some tests to get to the bottom of the gastroenteritis (upset stomach). This may include some blood tests, a scan of the abdomen, a urine analysis and a faecal examination.
Treatment will depend on the cause of the vomiting and diarrhoea, as well as on how unwell the patient is. For some, we may need to treat them in the hospital and provide intravenous fluids, anti-nausea and other supportive medicines. The most important factor is looking for a diagnosis, which can then allow us to provide the most appropriate treatment.
