Due to individual differences, the size of the gallbladder will be different, but generally the normal gallbladder is 5 ~ 8 cm long and 3 ~ 5~8cm wide.
The gallbladder is pear-shaped or eggplant-shaped, located in the right upper abdomen, attached to the lower part of the liver and attached to the gallbladder fossa. Gallbladder is a very important organ of human body, and its main function is to store and concentrate bile. When the human body is on an empty stomach, the gallbladder will be full of bile, in a full state, and its shape will be larger. When people eat, the gallbladder will contract, allowing bile to be discharged into the intestine to help digestion, and the shape will become smaller after discharge. Gallbladder also has the function of regulating pressure. After cholecystectomy, the common bile duct is dilated, the sphincter ability is weakened, the mucus glands are increased or the bile duct wall is thickened, which will change the bile duct pressure. At this time, the gallbladder will excrete more bile to adjust the biliary tract pressure. If the patient's gallbladder is larger than the normal range, it may be chronic cholecystitis or cholecystolithiasis. Attention should be paid to this situation, relevant examinations should be carried out in time, and treatment should be carried out under the guidance of doctors. If the patient's gallbladder is small, smaller than the normal range, and the gallbladder wall is thickened, it may be suffering from gallbladder atrophy, so it is necessary to do relevant examinations in time, make a clear diagnosis and treat it in time.
Gallbladder is an important digestive organ of human body, which not only has the functions of storage, concentration and excretion (contraction); It also plays an important role in regulating the pressure of biliary tract inside and outside the liver; It also has important secretory and immune functions.
