Fatty liver has an effect on the results of liver elastography. It is best to wait until liver function is normal, usually when there is no significant inflammation of the liver cells, for a liver elastography to be more accurate. If a patient with fatty liver has abnormal liver function, this can affect the results of elastography. Fatty liver is a metabolic disease of the liver, mainly due to excessive fat deposition in the liver cells, resulting in liver steatosis. It is important to develop good habits, do not eat too greasy food, eat more vitamin-rich food, and appropriate physical exercise is very helpful to improve fatty liver. Don’t stay up late, take rest and get enough sleep, which is also helpful for liver function repair.
