Participants may also be asked to complete study questionnaires and provide blood samples during the study participation.

Inclusion Criteria:

1. Adults and children (age 2 or older) being managed or treated for nonalcoholic fatty liver disease. Diagnosis is based on the clinical judgement of the care provider.
