Condition
Fatty Liver Disease (MASLD)
MASLD, once called NAFLD, happens when too much fat builds up in the liver. It is not caused by heavy drinking. About 24% of US adults have it. A more serious form, called MASH, causes liver swelling and damage.
Common options
- Losing weight slowly. Losing 3% to 5% of your body weight can reduce liver fat.
- Losing 7% to 10% of your body weight may be needed to reduce liver swelling and scarring.
- Eating healthy foods and watching portion sizes.
- Staying physically active. This helps even without weight loss.
- Vaccines your provider may recommend, such as for hepatitis A and B, flu and pneumococcal disease.
- Treatment for complications if the disease leads to cirrhosis, or a liver transplant in some cases.
When to see a doctor
- If you have type 2 diabetes or obesity. These raise your risk.
- If blood tests show abnormal liver results.
- Before taking supplements or herbal remedies. Some can damage the liver.
- Before stopping any medicine. Only stop if your provider tells you to.
Research studies
Researchers are studying new treatments for fatty liver disease. A clinical study is one option you can discuss with your doctor.
