After gallbladder removal, the function of storing and concentrating bile is significantly affected, resulting in a lack of concentrated bile after eating, which has a significant impact on the digestion and absorption of fat; on the other hand, a large amount of bile salts will continuously enter the intestine, especially the colon, promoting intestinal peristalsis, both of which will lead to an increase in diarrhea symptoms. However, diarrhea symptoms are usually temporary and can gradually resolve after three months, mainly due to the compensatory dilation of the biliary tract and the temporary storage of bile, thus gradually reducing the effects of these two aspects. However, a small number of patients do clinically present with persistent diarrhea symptoms, mainly related to poor compensatory function. It needs to be alleviated by adjusting the dietary structure and carrying out clinical treatment, for example, in daily life, one should pay attention to the dietary pattern, avoid eating stimulating and undigestible foods such as high-fat, greasy, raw and cold, spicy foods, and avoid drinking alcohol. If the diarrhea symptoms are more serious, you can also take relevant oral medications for treatment, such as loperamide hydrochloride or montelukast.
