Whether gallbladder wall thickening of 5mm can be recovered needs to be judged according to the cause of gallbladder wall thickening. If the thickening of gallbladder wall is caused by acute cholecystitis, which is often caused by obstruction of lymphatic and venous return, anti-inflammatory drugs are usually taken to treat it, and after controlling the inflammation, the wall of the gallbladder can be recovered gradually; when the inflammation is recurrent and proliferating, stimulating the wall of the gallbladder and causing chronic inflammation resulting in the thickening of the wall of the gallbladder, the thickening of gallbladder wall is unable to be recovered. If the thickening of gallbladder wall is caused by gallbladder cancer, the degree of malignancy is extremely high and cannot be recovered either. Surgery should be performed as early as possible to remove the diseased area and local tissues, and the surrounding lymph nodes should be cleared to avoid recurrence and metastasis. It should be noted that the thickening of gallbladder wall should have a light diet, eat more fresh fruits and vegetables, avoid spicy and stimulating food, and go to the hospital for regular checkups.
