An ultrasound that says fatty liver is present on one side and absent on the other side refers to an inhomogeneous fatty liver, indicating that the location of fat deposits in the liver is more limited. Fatty liver is a lesion caused by an excessive accumulation of fat in the liver cells. There are many types of fatty liver. Usually, when ultrasound says that fatty liver is present on one side and absent on the other side, it means that the location of fat accumulation within the liver cells is more limited, and not the whole liver is infiltrated with fat, which means that lipids are not evenly distributed, and in clinical practice, it is mostly referred to as inhomogeneous fatty liver. Uneven fatty liver is a relatively rare type of fatty liver. Studies have shown that the causes of uneven fatty liver include prolonged alcohol consumption, excessive nutrition, heredity, and too little exercise. Patients at this time need to adjust the diet structure, active sports, exercise. To summarize, patients need to cooperate with doctors to complete other relevant examinations to clarify the specific causes, cooperate with doctors to actively treat, go to the hospital on time for follow-up, and closely monitor the changes in the condition.
