As there is no standard treatment for fatty liver disease, which may be caused by a variety of factors, there is no specific time frame for healing, according to Mayo Clinic and Healthline. Fatty liver is often treated by managing underlying medical conditions such as obesity, hepatitis or alcoholism.
Maintaining a healthy weight, avoiding alcohol and choosing a healthy diet reduce the risk of fatty liver, states Healthline. Some factors that increase risk of fatty liver include malnutrition; overuse of medications such as acetaminophen; metabolic syndrome; and high triglyceride levels. Acute fatty liver, although rare, may also develop during pregnancy.
