There are two reasons for gallbladder shrinkage, one is that the length, width and height of the gallbladder, as well as the volume of the gallbladder itself, are smaller than normal, but at this time there are no clinical symptoms, and there is no history of gallbladder stones, gallbladder polyps or cholecystitis. At this time, the gallbladder function is normal, and the patient can continue to be observed and does not need clinical treatment. You should pay attention to your diet and avoid eating too much high cholesterol food in your daily life. Another condition is gallbladder atrophy due to recurrent cholecystitis. The shrinkage of the gallbladder is only a change in appearance, but the function of the gallbladder is likely to have been significantly reduced or lost. This will not only affect the patient’s quality of life, but may also lead to gallbladder cancer. In this case, surgery should be considered in time and should not be treated by diet or medication, and laparoscopic cholecystectomy is the preferred method of surgical treatment.
