NAFL (Nonalcoholic fatty liver)
Nonalcoholic fatty liver, or NAFL, means that your liver contains excess fat but little to no inflammation. This type of NAFLD usually does not cause liver damage but may cause pain due to the liver being larger than normal. Most people with NAFLD have NAFL.
NASH (Nonalcoholic steatohepatitis)
Nonalcoholic steatohepatitis (NASH) means that there is inflammation, as well as extra fat, in your liver. This damage can cause permanent scarring and lead to liver cancer. NASH is much less common than NAFL.
Risk and Prevention
The cause of NAFLD is unknown. However, your genetics, eating plan and certain health conditions may increase your chance of developing the disease. Factors that can make you more likely to develop NAFLD include:
- Being overweight or obese
- Having type 2 diabetes
- Being insulin resistant
- High levels of triglycerides
- Abnormal cholesterol levels
- Having metabolic syndrome
- Having polycystic ovary syndrome (PCOS)
- Physical inactivity
- Consuming high amounts of sugar
You may be able to prevent NAFLD from developing. Behaviors that may help offset NAFLD include:
Treatment
Gradual weight loss through lifestyle changes is recommended to treat both types of NAFLD. Losing weight can reduce fat, inflammation and scarring in the liver. A combination of approaches to weight loss may be most effective for NAFLD treatment. There is no medicine approved for NAFLD treatment. However, anti-obesity and antidiabetic drugs can help reduce fat in the liver and improve insulin resistance. Recommended treatment options include:
Healthy Meals:
Eating less calories and fat can improve gut health and insulin resistance for those with NAFLD. Limiting sugars is also recommended.
Physical Activity:
Exercise helps reduce fat in the liver, even without losing weight. Try to achieve 150 minutes each week, though every minute of activity counts!
