Vomiting is one of the most common presenting problems seen in practice. Acute vomiting can be self-limiting but, on the other side of the spectrum, it may be due to a life-threatening disease for which medical management and/or surgical treatment is essential. When presented with a patient with acute vomiting, it can be challenging to decide whether a specific patient should be prescribed supportive treatment alone or whether that patient should also have further diagnostic tests performed. This webinar highlights some of the circumstances that might point towards the need of further diagnostic tests in patients with acute-onset vomiting. However, even if a patient seems clinically stable and is deemed to only need supportive treatment at one-point, clinical deterioration may ensue, and further testing may later be needed.
