Prevalence of nonalcoholic fatty liver disease (NAFLD) is higher in people with obesity compared with the general population,1-4 however, the management of people with obesity does not always involve monitoring liver health.
A number of genetic factors that increase the risk of NAFLD development are exacerbated by obesity, causing individuals to be significantly more likely to experience liver injury and fibrosis.5,6 It is therefore important to consider hepatic outcomes in people with obesity and develop management strategies to avoid potentially serious health implications.
Best practice guidelines for the management of NAFLD patients have recently been developed, however, some gaps remain.7 While current guidelines cannot yet recommend an optimal care pathway, there is some guidance available regarding the monitoring, assessment and referral of people with suspected NAFLD, in particular those at risk of advanced fibrosis due to nonalcoholic steatohepatitis (NASH), which includes people with obesity.7
Exploring lifestyle interventions for patients with NAFLD, including diet, weight loss and exercise.
This page looks at how surgical interventions, though extreme, may be an option for patients with severe weight loss issues or advanced fibrosis due to NASH.
Obesity and NASH
This page focuses on the prevalence of NASH in people with obesity, fibrosis, assessment and diagnosis and referral and management.
