onalcoholic Fatty Liver Disease (NAFLD)
It’s not clear what causes this type of fatty liver disease. It tends to run in families.
It’s also more likely to happen to those who are middle-aged and overweight or obese. People like that often have high cholesterol and diabetes as well.
Other causes are:
Autoimmune or inherited liver disease
Fast weight loss
Some studies show that too much bacteria in your small intestine and other changes in the intestine may be linked to nonalcoholic fatty liver disease.
Acute Fatty Liver of Pregnancy
It’s rare, but fat can build up in your liver when you’re pregnant. This could be risky for both you and your baby. It could lead to liver or kidney failure in either of you. It might also cause a serious infection or bleeding.
No one fully understands why fatty liver happens during pregnancy, but hormones may play a role.
Once you get a diagnosis, it’s important that your baby gets delivered as soon as possible. Although you may need intensive care for several days, your liver often returns to normal in a few weeks.
You might have fatty liver disease and not realize it. There are often no symptoms at first. As time goes on, often years or even decades, you can get problems like:
Loss of weight or appetite
Confusion, poor judgment, or trouble concentrating
You might have some other symptoms, too. Your liver may get larger. You could have a pain in the center or right upper part of your belly. And the skin on your neck or under your arms may have dark, colored patches.
If you have alcoholic liver disease, you may notice that the symptoms get worse after a period of heavy drinking.
You could also get cirrhosis, a scarring of your liver. When that happens, you might have:
Buildup of fluid in your body
Wasting of your muscles
Bleeding inside your body
Jaundice (yellowing of skin and eyes)
