Hepatitis without drinking alcohol?

GGT (Gamma-glutamyl transpeptidase) is used as a diagnostic marker for liver disease, but even if GGT is within the reference range, it is possible to have serious liver disease.
 
The disease is NASH (Non-alcoholic steatohepatitis).
NASH is the most extreme form of Non-alcoholic fatty liver disease.
Most people have few or no symptoms except fatigue, malaise or low appetite so when it is found, there is a progressed case.
 
5-20% of people who were diagnosed as NASH will have cirrhosis within 5 to 10 years and in 5 years, at most, 15% of people who had cirrhosis will have liver cancer.
 
The cause of NASH is fatty liver which is the condition that a lot of fat is accumulated in liver.
There are two main causes of fatty liver disease.
 
1. Drinking too much alcohol. Liver puts priority on the metabolism of alcohol which is high in toxicity, postponing the metabolism of fat. As a result, the postponed fat is stored in liver.
 
2. Obesity caused by lack of exercise and disordered eating habit.
If your weight is gained by 20 kg (45 lbs.) compared to the weight of when you were age of 20s, you should have visceral fat in addition to fat around your body and it is no wonder that you have fat in your liver.
