The absence of gallbladder has little effect on patients because gallbladder is a storage organ of human body, mainly storing bile produced from liver and also has the function of concentrating bile, and does not produce digestive juices, so gallbladder removal will not affect the digestive function, not to mention the life expectancy of ordinary people. After gallbladder removal, some patients may have fatty diarrhea, which is mainly manifested as diarrhea after eating fatty food, but the symptoms can be gradually reduced or disappear with the extension of time. After gallbladder removal, patients should pay attention to their diet, for example, try not to drink alcoholic beverages, consume vitamin-rich fruits and fresh green vegetables, consume low-fat, high-quality protein foods, such as fresh fish and shrimp, and go to the hospital for regular review of abdominal ultrasound and liver function.
