Thank you for the information,
Steatosis means deposition or infiltration of fat in the liver tissue.
The common causes are over weight or obesity, excess intake of alcohol.
But you do not have any such issue.
Still I would advise to avoid alcohol totally.
Different other causes can be there.
High cholesterol, triglycerides in the blood, rapid weight loss, malnutrition can be factors.
If you have not checked those levels, you can have those.
Fatty liver itself may not cause any problem but if it damages the liver, it can lead to cirrhosis of liver which is a matter of concern.
As your enzyme levels are good, it is usually not worrying.
You can have regular exercise, low fat diet & increase in fresh vegetables, fruits.
You should have regular follow ups with doctor.
Doctor can take CT/ MRI if he feels necessary.
I hope this information helps.
If you need any further clarification, please feel free to ask.
