Non-A-E hepatitis


Other Names:
Viral hepatitis non-A,-B,-C,-D,-E; Hepatitis X
Non-A-E hepatitis, sometimes referred to as hepatitis X, is a disease of the liver that is diagnosed when there is swelling of the liver (hepatitis) but examination and testing does not identify a cause.  Symptoms of non-A-E hepatitis may include feeling tired or unwell (malaise), nausea, vomiting, pain in the abdomen, and fever.  Non-A-E hepatitis usually goes away on its own, but it can become a chronic condition in a small proportion (12%) of affected individuals.  The cause of non-A-E hepatitis is currently unknown.[1]
