The gallbladder is located in the upper part of the right side of the abdomen, directly below the liver , and is approximately 10 cm long, and its shape resembles a pear or a pear, and it can be said that the primary function of the gallbladder is to store bile Produced by the liver, where this juice travels from the liver to the gallbladder through the bile duct, and the juice remains stored in the gallbladder until the small intestine is excreted for a hormone known as cholecystokinin, and then the juice is released into the small intestine to help the digestion of food fats, and it should be noted that despite the importance of the gallbladder, the body can live without it healthily, for example what happens in Some disorders and health problems that require the removal of the gallbladder, and then it can be said that the body compensates the store of the gallbladder by storing this juice in the bile duct , and this may rarely cause this channel to expand and enlarge, but this is not a big problem.

To perform its functions as required.
- Gallstones: Gallstones can be defined as small solid deposits, and they often consist of cholesterol in the bile, and it is worth noting that gallstones are often small in size and reach a few millimeters in diameter, but they may grow and increase in size to become a few centimeters. In fact, some people may suffer from one stone in the gallbladder , and some may suffer from several stones, and often the patient does not feel the presence of the stones until they cause a problem, such as infection, pain, and infections.
- Bile duct stones: Often these stones were originally gallstones, but they moved into the bile duct and were deposited in it, and then they are known as secondary bile duct stones, and in rare cases they may be stones formed for the first time in the bile duct and then they are known as primary bile duct stones, and in fact they are considered stones Primary are more infectious than secondary.
- Infection of the bile duct: Infection may appear in the bile duct when a blockage occurs in it. In fact, treatment is considered effective if it is done in the early stages of the disease, that is, the infection is discovered early, because late detection of it may cause the death of the injured.
- Gallbladder abscess: gallstones may be accompanied by the appearance of pus, which is a collection of white blood cells , dead tissue, and bacteria, and pus is considered fatal if it is left without diagnosis and treatment, due to the possibility of its spread in the body, and it should be noted that the most important symptoms of a gallbladder abscess is the feeling of the injured Severe pain in the abdomen .
