Nonalcoholic Fatty Liver Disease: Symptoms, Causes, And More

non alcoholic fatty liver disease

This usually means a stage of F2 or more on the most widely used F0 to F4 scale, but other scales and hence other definitions can be used. The presence of scar tissue is regarded as a sign that the liver is not able to cope with the damage that has occurred. Unfortunately, this is something that is not widely available and is generally poorly supported by the healthcare system. You are, however, more likely to have NAFLD if you have obesity and T2D, with NAFLD occurring in nearly 8 to 9 out of 10 (80 to 90%) people living with obesity and in 5-7 out of 10 (50-70%) people living with type 2 diabetes. The number of people with NAFLD increases progressively with age.

This is a serious condition where normal liver tissue is replaced by a lot of fibrosis (scarring). Most people with NAFLD only have the early stage – ‘simple fatty liver’. Only a minority will progress to develop inflammation of the liver (called non-alcoholic steatohepatitis, or NASH). And, only a minority of people with NASH will progress to develop cirrhosis. It is not clear why some people with simple fatty liver progress to the more severe forms of NAFLD, and most do not. Most patients with NAFL will have a benign, nonprogressive disease course.

Besides imaging, several individual blood parameters are available for basically the same purpose. Many of them are also still experimental but the interpretation of their results is comparable to liver stiffness article source measurements. A percentage of 30% corresponds to very severe steatosis, as it is a percentage of total weight; as such, this percentage cannot be directly compared to observations made on a liver biopsy.

Some patients will evolve to NASH, wherein steatosis is accompanied by liver cell damage and inflammation. This can go along with the accumulation the advantage of scar tissue or fibrosis. In a subset of patients with NASH, more and more scar tissue will accumulate and ultimately result in cirrhosis.

In cirrhosis, at right, scar tissue replaces healthy liver tissue. HELLP stands for haemolysis-elevated liver tests-low platelet lowest price count. This rare syndrome is a life-threatening condition during pregnancy, the course of which is difficult to predict.

The liver blood tests are usually abnormal, but not always.86,87 If abnormal, they are usually only slightly elevated, which should not be considered as a sign of mild disease. Surprisingly, the degree of abnormality of the blood tests does not reliably predict the severity of liver injury. This means that liver tests may be normal or show only minor elevations and you still can have advanced disease. These figures should be treated with some caution because they are based on studies that looked at the biopsies of patients and not everyone needs to have a liver biopsy. It is possible that the individuals who had liver biopsies may have already had more advanced NAFLD and so the aforementioned figures may overestimate the number of people who progress to advanced fibrosis and cirrhosis.

Even if you don’t feel any symptoms from NAFLD, that doesn’t mean liver scarring isn’t occurring. If you believe you may be at risk for developing this condition, your doctor can help you figure out if you need any additional testing done. The condition is typically diagnosed after a blood test finds higher-than-normal levels of liver enzymes. While some individuals who are diagnosed with NAFLD have no previous risk factors, there are some lifestyle factors that can increase the likelihood of a NAFLD diagnosis. When you are diagnosed with NAFL, you have fat in your liver, but little to no inflammation and no liver damage.
