“…Several factors may be involved in the pathophysiology of MAFLD. Obesity is presented as an independent risk factor for triglyceride deposition in hepatocytes 33 . The underlying constraints are not yet fully understood 34 , but it is believed the deposition of triglycerides in liver tissue may come from diet fat derived from intestinal kilomicrons, circulating FFA from the lipolysis of AT, de novo hepatic lipogenesis, from the reduction of lipid oxidation, and by secretion of triglycerides by the liver 35 .…”

The mechanisms involved in the association between obesity and MAFLD are specific 33 , since the MAFLD pathophysiology also involves a complex interaction between its determinants 36 . The triglyceride overload in hepatocytes observed in obesity conditions favor the state of lipotoxicity 37 .…”

“…A prevalência nos EUA é estimada em 24%, na Europa em 23%, e são relatadas taxas de 14% na África. 4 O diagnóstico pode ser realizado por exames de imagem como a ultrassonografia, tomografia computadorizada, ressonância magnética e elastografia hepática, embora o padrão ouro seja o estudo histológico por biópsia hepática. A ultrassonografia é o método utilizado em larga escala pelo seu baixo custo, ampla disponibilidade e por não causar malefícios, embora não seja tão sensível quanto a biópsia hepática que, apesar de ser um procedimento seguro, pode causar intercorrências como sangramentos e infecções.…”
