[Obesity-fatty liver: the role of the pediatrician].

Pediatric nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children and adolescents that cannot be attributed to other genetic, infectious, toxic or nutritional causes. It can evolve from simple steatosis to nonalcoholic steatohepatitis, and can progress to advanced fibrosis, cirrhosis, and an increased risk of hepatocellular carcinoma. Its treatment consists of a change in lifestyle, promoting weight loss with the incorporation of a healthy diet and increased physical activity. To achieve this goal, family support is essential. These measures will benefit the physical, mental and social quality of life of these children. The objective of this communication is to sensitize the pediatric community about the importance of managing these patients and their family environment, committing to modifying socioeconomic risk factors, to achieve a better quality of life for future generations.
