Unexplained nausea can have various causes, ranging in severity from 'minor' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose unexplained nausea, we could:
|Irritable Bowel Syndrome||12%||Unlikely|
|Non-Hodgkin's Lymphoma||2%||Ruled out|
|Low Carbohydrate Diet Consequences||1%||Ruled out|
|Chronic Renal Insufficiency||1%||Ruled out|
|West Nile Virus||0%||Ruled out|
