Additionally, IgG4-related hepatobiliary disease is also classified under this category. Autoimmune hepatitis can occur at any age, but most patients are over 40 years old. Women are more susceptible to the disease, with a male-to-female ratio of approximately 1:4.

However, if the patient is in a severe stage, they may exhibit symptoms of chronic hepatitis, such as fatigue, loss of appetite, nausea, vomiting, and dull pain in the right upper abdomen.
