The gallbladder is a small organ located beneath the liver. Its primary function is to store and concentrate bile, which is a fluid produced by the liver to aid in the digestion of fats.

Cholesterol gallstones are the most common type, accounting for about 80% of all gallstones. They are composed primarily of cholesterol, with small amounts of other substances such as bile pigments and calcium.

The primary risk factor for developing cholesterol gallstones is high levels of cholesterol in the bile. This can occur due to factors such as obesity, rapid weight loss, and diabetes.

Abdominal pain is a common symptom of gallstones. The pain is typically located in the upper right abdomen and may be sharp or dull. It can also be accompanied by nausea and vomiting.

Cholecystitis is the most common complication of gallstones. It is an inflammation of the gallbladder that can be caused by a gallstone blocking the bile duct.

Surgery is the primary treatment for gallstones. The most common surgical procedure is laparoscopic cholecystectomy, which involves removing the gallbladder through small incisions.

Lifestyle changes can help reduce the risk of developing gallstones and may also help prevent recurrence after surgery. These changes include maintaining a healthy weight, eating a balanced diet, and getting regular exercise.

Eggs are high in cholesterol and should be limited in a gallstone prevention diet. Other foods high in cholesterol include red meat, processed meats, and full-fat dairy products.

Individuals with a history of gallstones are recommended to undergo gallbladder ultrasound examinations every year to monitor for recurrence and potential complications.

Ultrasound is the most commonly used imaging technique to diagnose gallstones. It is a non-invasive procedure that uses sound waves to create images of the gallbladder and surrounding structures.

Medications can be used to dissolve gallstones, reduce inflammation, and prevent the formation of new gallstones. However, surgery is often the preferred treatment for symptomatic gallstones.

Ursodeoxycholic acid (UDCA) is a medication commonly used to dissolve cholesterol gallstones. It works by reducing the cholesterol content of the bile and promoting the dissolution of gallstones.

The recommended duration of treatment with ursodeoxycholic acid (UDCA) for dissolving gallstones is typically 2 years. The medication is usually taken once or twice daily.

Diarrhea is a potential side effect of ursodeoxycholic acid (UDCA) treatment. Other potential side effects include nausea, abdominal pain, and skin rash.

The success rate of ursodeoxycholic acid (UDCA) treatment for dissolving gallstones is typically around 40-50%. The success rate may vary depending on factors such as the size and composition of the gallstones.
