Welcome to HCM,
You have gastric problem which may not be related with fatty liver
so visit a Gastroenterologist and see if you have Acid Peptic disease
and may be evaluated by upper GI Endoscopy
You must also be investigated for H.Pylori if there treat with triple therapy.
Take care of your diet and if you take alcohol stop it and if you smoke quit it.
Many times fatty liver is asymptomatic and detected in routine screening tests,It is commonly associated with Alcohol,Diabetes
but there are many other causes
If you are obese reduce your weight .
Many drugs can cause it so try to find out cause because treatment depends on it.
Please Take care
