The thickening and roughness of the gallbladder wall of about 6mm usually refers to the thickening and roughness of the wall of the gallbladder of about 6mm during abdominal ultrasonography, which often suggests that the patient has chronic cholecystitis. Chronic cholecystitis may cause abnormal thickening of the gallbladder wall and pathological changes such as exudation due to repeated stimulation of the gallbladder wall by inflammation over a long period of time, often accompanied by clinical symptoms such as epigastric fullness and discomfort, pain, and fever. On ultrasound, the wall of the gallbladder is often thickened and rough. When the test results suggest that the gallbladder wall is thickened and rough, you should go to the hospital in time, and choose reasonable treatment under the guidance of the doctor, so as to avoid delaying the condition.
