Fatty liver? - fatty liver causes more condition_symptoms

Passed my 23 years in healthy son recently completed a physical examination. He was not free of problems. The doctor said his liver appeared enlarged and sent for blood tests and ultrasound. The doctor said the ultrasound was normal and nothing working found in the blood, but I want my son to work more blood to check your iron and say that it is a 'liver were fat. My son does not drink and take no medications, cause fatty liver. 6'tall you are over, and weighs about 220, which is a bit overweight. Has anyone any idea what could be searched, and the doctor used the fatty liver might be damaged? to take creatine supplements, so many years as a fan and went to the gym. This could be related?
