Reduction in steatosis was associated with a reduction in glycemic parameters and \u03b3\u2010glutamyl transpeptidase. Reduction in lobular inflammation was associated with reductions in liver enzyme levels and hemoglobin A1c. Changes in hepatic fibrosis were not associated with metabolic or biochemical changes but were related to baseline fibrosis severity and the presence of diabetes. Unexpectedly, weight reduction significantly lowered platelet counts and elevated the fibrosis\u20104 index.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>LSG improves liver histopathology of MASLD in Japanese participants with severe obesity.
