Dear doctor, I have done abdomen ultrasound for kidney stones, every thing went normal but found grade-I fatty liver(125mm liver size) surprisingly, I'm non alcoholic and eats non veg twice month, wt-76 kgs & ht- 5.8 in and bmi 24.3. I'll not eat out side foods and takes only home food, I will not eat bakery items and trans fats etc & still I was found to be grade-I which was worried a lot to me. I have attached my usg report for this query. I will strictly follow the diet but still the issue was found surprisingly. I'll eat rice and vegetable curry in afternoon and chapati for dinner before 8: 30 and non Oil food like idly, oats, wheat upma, and dosa for breakfast. Although I was.on normal diet but found this, Please help me whether it was an serious issue. With my issue thanks in advance.
