Hi thanks for asking question.
Noted you have
fatty liver detection one year ago...
With lifestyle modification it can be resolved in few month.So in biopsy right now you have no fatty liver...
Anyway you might have just now gastric
indigestion with inflammation of gastrointestinal tract...
For few days take soft and bland diet...
Fruits more.with drinking hot water...
Take more water..
Avoid non veg and fatty food for few days..
Apple, whole grain , wheat bran like fiber food taken more...
Perform your
widal test to rule out typhoid.
If needed cefixime like antibiotic used.
If still problem remain USG ,
endoscopy like further investigation done...
Take care.
