What are the signs and symptoms of fatty liver?

Fatty liver disease rarely causes symptoms until the liver disease is far advanced. Fatty liver usually is found or suspected when:

  • Abnormal liver tests are found on routine blood testing
  • Fat is seen ultrasonographically when ultrasonography of the abdomen is performed for other reasons, for example, the diagnosis of gallstones
  • Infrequently when the liver is enlarged on physical examination of a patient

When the liver disease is far advanced (cirrhosis), signs and symptoms of cirrhosis predominate. These include:

  • Excessive bleeding due to the inability of the liver to make blood-clotting proteins
  • Jaundice due to the inability of the liver to eliminate bilirubin from the blood
  • Gastrointestinal bleeding due to portal hypertension that increases the pressure in intestinal blood vessels
  • Fluid accumulation due to portal hypertension that causes fluid to leak from blood vessels and the inability of the liver to make the major blood protein, albumin
  • Mental changes (encephalopathy) due to the liver's inability to eliminate chemicals from the body that are toxic to the brain. Coma may occur.
  • Liver cancer

What is the difference between nonalcoholic fatty liver and steatohepatitis (NASH)?

As discussed previously, the difference between isolated, nonalcoholic fatty liver and steatohepatitis (NASH) is the presence of inflammation and damage to the liver cells in NASH; in both, the liver has increased amounts of fat. Although about a third of the general population has fatty liver, approximately 10% have NASH. Approximately one third of patients with nonalcoholic fatty liver disease have NASH. Although fatty liver and NASH appear to arise under the same conditions, it does not appear that fatty liver progresses to NASH. Thus, whether a patient is to develop fatty liver versus NASH is determined very early during the accumulation of fat, although it is unclear what factors determine this. It is believed that the inflammation and damage of liver cells are caused by the toxic effects of the fatty acids released by fat cells, but fatty acids in the blood are elevated in both fatty liver and NASH. Perhaps the difference is explained by genetic susceptibility as suggested by preliminary data.

The consequences of fat in the liver depend greatly on the presence or absence of inflammation and damage in the liver, i.e., whether there is fat alone or NASH is present. Isolated fatty liver does not progress to important liver disease. NASH, on the other hand, can progress through the formation of scar (fibrous tissue) to cirrhosis. The complications of cirrhosis, primarily gastrointestinal bleeding, liver failure, and liver cancer, then may occur.

What is the relationship between nonalcoholic fatty liver disease, obesity, and diabetes?

As discussed previously, obesity and diabetes have important roles in the development of fatty liver. Whereas one third of the general population (which includes obese and people with diabetes) may develop nonalcoholic fatty liver disease, more than two thirds of people with diabetes develop nonalcoholic fatty liver disease. Among patients who are very obese and undergoing surgery for their obesity, the majority have nonalcoholic fatty liver disease. Moreover, whereas the risk of NASH is less than 5% among lean persons, the risk is more than a third among the obese. Fatty liver increases both in prevalence as well as severity as the degree of obesity increases. The increases begin at weights that are considered overweight - i.e., less than obese.

What is the relationship between nonalcoholic fatty liver disease and the metabolic syndrome?

The metabolic syndrome is a syndrome defined by the association of several metabolic abnormalities that are believed to have a common cause. These metabolic abnormalities result in

  • obesity,
  • elevated blood triglycerides,
  • low high density lipoprotein (HDL) cholesterol,
  • high blood pressure, and
  • elevated blood sugar (diabetes).

Nonalcoholic fatty liver disease is considered a manifestation of the metabolic syndrome and thus occurs frequently with the other manifestations of the syndrome. Occasionally it may occur without the other abnormalities of the syndrome.

Comment from: shelley2655, 55-64 Female (Patient) Published: February 11

I was diagnosed with nonalcoholic fatty liver disease on Friday. I was quite shocked and the doctor's physician assistant didn"t explain much about it, just that my enzymes were elevated and to eat a fat free diet. I was also told this could turn into cirrhosis of the liver, pretty scary. I have pain in the right side just under my ribcage and it radiates around to my back. I did find that laying on my right side helps relieve the pain. I did some research and I had every symptom. GERD, change in bowel habits, flaky patches on my skin, tiredness, no energy, etc.

I wonder if treatment for breast cancer can cause fatty liver. I had large amounts of steroids to prevent allergic reaction. My eyes were yellow and I had a rash that itched and looked like poison ivy. At one point my toenails and fingernails turned yellow, were thick and raised up. I lost some toenails. They cancelled my treatment for those 2 weeks. I told my doctor that I thought I needed to do a liver cleanse because I was toxic. They told me I had a fatty liver.
