Hepatitis E is a liver infection caused by the hepatitis E virus (HEV). It spreads through contaminated water or food. In most healthy people, it resolves on its own within a few weeks. However, in certain groups'such as pregnant women or people with weakened immune systems-it can lead to more serious illness.
Dr. Chadha reviews your symptoms, travel and food history, and any other risk factors for HEV exposure.
We check liver enzyme levels (ALT, AST) and order specific HEV antibody tests to confirm acute infection.
An abdominal ultrasound evaluates liver size and texture and helps rule out other liver conditions.
