The upper border of the liver is generally located in the right mid-clavicular line between the fifth rib, thin and tall people or people with physical illness, may be in the sixth rib. Doctors judge the position of the upper liver border by the sound of the percussion, and the position of the upper liver border is generally at the fifth intercostal space of the right midclavicular line in the well-proportioned people, and it will be lowered by one intercostal space in the tall and thin people, so the upper liver border of this kind of people is generally at the sixth intercostal space, which is a normal phenomenon. If the patient has some physical lesions, such as emphysema, cirrhosis and other diseases, it will also lead to a change in the shape of the liver, and the size of the liver will be reduced, so it will fall from the fifth intercostal space to the sixth intercostal space. If the patient’s liver is not feeling well, it is recommended to go to the regular hospital to determine the cause of the disease through ultrasound or abdominal CT examination, and to treat accordingly under the guidance of the doctor.
