What causes gallbladder swelling?

The symptoms of gallbladder swelling are usually caused by biliary obstruction, which prevents bile from being discharged, resulting in increased gallbladder tension and congestion and edema of bile duct mucosa. Biliary obstruction may be caused by cystic duct stones and common bile duct stones. It may also be caused by diseases such as biliary ascariasis. If it is caused by stones, general resection surgery or minimally invasive surgery can be selected according to the condition. If it is caused by biliary ascariasis, patients can be treated with anthelmintic drugs such as levamisole. During this period, patients need to drink more water and pay attention to rest.
