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.
