What does 0mm below the rib of the liver mean?

Liver 0mm below the ribcage indicates that no abnormalities such as enlargement or hyperplasia of the liver are found.
Under normal circumstances, the liver is mostly covered by the rib arch, and most normal people can only touch the liver margin of about 2-3cm in the diaphragmatic angle of the right rib and under the xiphoid process, and generally the normal liver cannot be touched under the rib margin.
In adults, if the liver can be touched under the rib margin, it suggests that the liver is enlarged or hyperplasia and other abnormalities, which is common in the acute stage of hepatitis, hepatic stasis, right heart failure, compensatory hyperplasia at the early stage of cirrhosis, tumor occupation, etc., and requires further examination.
The phenomenon of touching the liver under the rib margin in children, in the absence of other obvious causes, is mainly considered to be the result of imperfect growth and development, and high activity of the liver, and is generally not a pathological phenomenon caused by diseases.
If liver enlargement or corresponding discomfort symptoms are found, further color Doppler ultrasound and CT examination should be carried out in a timely manner to clarify the cause and further treatment.
