Although weight loss surgery (bariatric surgery) can be beneficial in reducing liver fat and damage, and in decreasing the risk of further health complications, it is typically not recommended as a standalone treatment for NASH. Instead, it may be indicated in individuals with NASH with moderate to severe (Class II or Class III) obesity and/or those who have other cardiometabolic comorbidities such as type 2 diabetes.
Weight loss surgery is not recommended for people with decompensated liver cirrhosis, as it can increase the risk for postoperative complications and mortality.[1][2]
