Abstract
Nonalcoholic steatohepatitis (NASH) is a stage of nonalcoholic fatty liver disease
(NAFLD), and in most patients, is associated with obesity and the metabolic syndrome.
The current best treatment of NAFLD and NASH is weight reduction with the current
options being life style modifications, with or without pharmaceuticals, and bariatric
surgery. Bariatric surgery is an effective treatment option for individuals who are
severely obese (body mass index ≥ 35 kg/m2), and provides for long-term weight loss and resolution of obesity-associated diseases
in most patients. Regression and/or histologic improvement of NASH have been documented
after bariatric surgery. We review the available literature reporting on the impact
of the various bariatric surgery techniques on NASH.
