Vomiting has been defined as the forceful expulsion of the contents of the stomach, duodenum, or jejunum through the oral cavity. While nausea and vomiting are often thought to exist on a temporal continuum, this is not always the case. There are situations when severe nausea may be present without emesis and less frequently, when emesis may be present without preceding nausea.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0002017","HPO_Synonym__c":"Nausea and vomiting","HPO_Name__c":"Nausea and vomiting","Feature_System__c":"Digestive System","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:727","HPO_Frequency__c":"Frequent (30-79%)","Feature__r":{"HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0005244","HPO_Synonym__c":"Death of digestive organ tissue due to poor blood supply; GI infarctions","HPO_Name__c":"Gastrointestinal infarctions","Feature_System__c":"Digestive System","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:727","HPO_Frequency__c":"Occasional (5-29%)","Feature__r":{"HPO_Description__c":"An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) localized to the chest.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0100749","HPO_Synonym__c":"Chest pain; Thoracic pain","HPO_Name__c":"Chest pain","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:727","HPO_Frequency__c":"Frequent (30-79%)","Feature__r":{"HPO_Description__c":"An increased erythrocyte sedimentation rate (ESR).
