Gallbladder polyps 3mm generally do not require special treatment and can be adjusted from lifestyle first. Many people are found to have gallbladder polyps during physical examinations, and its prevalence in adults is about 5%-10%. The etiology of gallbladder polyps is complex and may be related to chronic cholecystitis, gallbladder stones and disorders of cholesterol metabolism, ranging in size from a few millimeters to several centimeters. Most gallbladder polyps require only regular review. A small number of gallbladder polyps, such as those larger than 1 cm in diameter combined with gallbladder stones, or those found to be significantly larger on regular review, have the potential to become malignant and are recommended to undergo surgery as soon as possible. When people have problems such as obesity, smoking, hyperlipidemia, cirrhosis of the liver, anatomical abnormalities of the upper gastrointestinal tract and biliary tract, they are more likely to have gallbladder polyps, so they should pay attention to quit smoking and drinking, control their weight and eat regularly to prevent the gallbladder problems from being aggravated by their living habits.
