Vomiting is not a typical clinical manifestation of pulmonary embolism. For pulmonary embolism, typical symptoms generally include chest pain, coughing up blood, and difficulty breathing. Some patients may show atypical symptoms such as unexplained difficulty breathing, unexplained drops in blood pressure, fainting, and other related conditions. Additionally, some patients may exhibit arrhythmias. When the condition of a patient with pulmonary embolism becomes severe, it may be accompanied by significant respiratory failure or shock. In such cases, symptoms of vomiting might also be present. However, if there is just vomiting, the likelihood of pulmonary embolism is generally considered low, and other causes should be investigated first, such as gastrointestinal disorders.
