The gallbladder is located in the gallbladder fossa of the liver. Gallbladder is composed of mucosa, basal layer and adventitia, and its function is to concentrate and store bile. Although we know the location, composition and function of the gallbladder, some people don't know the normal size of the gallbladder, so they can't find it after the gallbladder is enlarged, so we need to know the normal size of the gallbladder.
First of all, what is the normal size of the gallbladder?
The normal size of a normal gallbladder is 3.5cm in short diameter and 8.0cm in long diameter. Gallbladder smaller than this range belongs to gallbladder shrinkage, gallbladder larger than this range belongs to gallbladder enlargement, and the causes of gallbladder enlargement and shrinkage are mostly caused by various diseases.
Second, what are the causes of gallbladder enlargement?
1. Gallbladder polyp: Gallbladder polyp refers to the protuberant lesion of gallbladder, which can induce gallbladder cancer. Cholesterol polyp is the most common gallbladder polyp with no obvious symptoms. Only a few patients will have discomfort such as upper abdominal pain.
2, cholecystitis: cholecystitis will occur when the gallbladder is infected by bacteria or chemicals, which is a multiple disease of the gallbladder. More common in middle-aged people, and more common in women.
3. Bile duct tumor: Because the common bile duct passes through the pancreatic head where most cancers originate. In rare cases, the bile duct is compressed by tumors transferred from other parts of the body, which leads to obstruction and then forms bile duct tumors.
Third, what are the reasons for the small gallbladder?
1. Congenital small gallbladder: During fetal development, due to various reasons, the gallbladder development is relatively small, or the gallbladder is smaller than the normal size after birth.
2, atrophic cholecystitis: due to gallbladder inflammation will recur when suffering from gallstones, gallbladder wall will produce fibrosis, inflammatory hyperplasia and so on. After repeated attacks, the gallbladder will gradually shrink. The shrunk gallbladder will lose its elasticity and become harder and smaller. In severe cases, it will be less than half its original size.
After knowing the normal size of the gallbladder, if it is found that the gallbladder becomes smaller or larger when passing the examination, it is necessary to conduct an examination to eliminate harmful reasons. Pay more attention to diet health and living habits. In normal times, it can prevent the abnormal change of gallbladder size, prevent the occurrence of other diseases and maintain a healthier body.
