Abstract
Obesity is a crucial health problem that is common today and may lead to systemic organ dysfunctions. In its treatment, bariatric surgeries are applied with increasing frequency and provide patients lose weight. However, it causes some complications in the post-operative period. Two of these rarely complications are acute liver failure and long-term chronic liver disease. Here, we present a case that died due to acute liver failure after bariatric surgery. If severe malnutrition persists in these patients, reversal surgery should be performed.
