Nonalcoholic steatohepatitis or NASH can be reversible.
The major feature in NASH is fat in the liver, along with inflammation and damage. Most people feel well and are not aware that they have a problem. Nevertheless, NASH can be severe and can lead to cirrhosis.
Both NASH and Fatty Liver are becoming more common, possibly because of the greater number of Americans with obesity.
Currently, no specific therapies for NASH exist. The most important recommendations are to lose weight, follow a healthy diet, increase physical activity and avoid alcohol.
If the cause for the inflammation is removed such as obesity for NASH, then the liver will rejuvenate and the damage will be reversed. If the damage continues it can lead to cirrhosis which is permanent. There are four stages. Fatty Liver, Inflammation, Fibrosis, Cirrhosis.
So the best thing you can do now is not overreact, eat right, lose weight, don't drink and follow up with your doctor in three months.
