There is a relationship between gallstones and fatty liver. Fatty liver is usually seen in patients who are obese and have high blood lipid levels, which can predispose them to fatty liver. High blood lipid levels usually show increased cholesterol and elevated triglycerides, and during an abdominal ultrasound or CT scan, low liver density and a high level of internal fat in the liver can be detected. Patients with gallstones are also associated with obesity and high cholesterol content. Generally, gallstones are found in obese patients, such as obese women over 40 years old, and patients with high cholesterol content may have high cholesterol content inside the gallbladder and in the middle of the bile, which may lead to the formation of gallstones after a long time. Therefore, patients with gallstones and fatty liver and obesity are all related to each other.
