Introduction
An asymptomatic 9mm gallstone, with no gallbladder wall thickening and normal gallbladder function, can be monitored regularly by ultrasound examinations (every 6–12 months) to track changes in the stone. Special treatment is not required at this stage, but attention should be paid to diet and lifestyle habits to avoid triggering symptoms. However, if a 9mm gallstone repeatedly causes right upper abdominal pain, nausea, or vomiting,
A 9mm gallstone is usually not serious if it is asymptomatic and without complications; however, it may become more severe if accompanied by symptoms such as abdominal pain or cholecystitis, or if the stone is in a particular location. If right upper abdominal pain, fever, or jaundice occurs, prompt medical attention is necessary.
For asymptomatic 9mm gallstones, if there is no gallbladder wall thickening and gallbladder function is normal, regular ultrasound monitoring (once every 6–12 months) is sufficient. No specific treatment is needed at this stage, but attention should be paid to diet and lifestyle habits to avoid triggering symptoms.
If a 9mm gallstone repeatedly causes right upper abdominal pain, nausea, vomiting, or is associated with cholecystitis or gallbladder polyps, it may lead to bile duct obstruction and cause serious complications such as cholangitis or pancreatitis. In such cases, timely intervention is required, with treatment options including medication or surgical removal of the gallbladder depending on the individual situation.
Daily care should include maintaining a low-fat diet, avoiding overeating and spicy or irritating foods, eating meals regularly to reduce abnormal gallbladder contractions, engaging in moderate exercise to control body weight, undergoing regular follow-up examinations as prescribed by a physician, and seeking immediate medical attention for symptoms such as abdominal pain—do not delay care.
