After cholecystectomy, liver protection is generally not needed. Generally speaking, the removal of gallbladder has little effect on the normal operation of liver function, so if the postoperative review of liver function does not show any obvious abnormality, it is generally not recommended to carry out special liver protection and liver protection treatment. The probability of steatorrhea will be significantly increased after gallbladder removal, therefore, it is recommended that after cholecystectomy, we should pay attention to a light diet, avoid eating high oil and high fat food such as fried chicken, hamburger, etc., and consume more fresh fruits and vegetables; and we should insist on jogging, swimming, and other aerobic exercises in order to positively control the body weight and blood lipids. After cholecystectomy, it is recommended to go to the outpatient clinic for regular follow-up to ensure that the surgical wound is dry and clean, and to test the liver function to ensure that it is within the normal range.
