Cholecystectomy is widely used in patients with recurrent attacks of chronic cholecystitis or gallbladder stones, which are more common in middle-aged and elderly female patients, especially those with obese bodies. After cholecystectomy, one should eat a reasonable diet and stay away from high cholesterol or greasy foods, because the onset of cholecystitis is related to greasy foods, which affect the metabolism of bile pigments and even lead to chronic inflammation secondary to the formation of gallstones. In addition, you should not overeat, especially high-fat food, which can easily stimulate the secretion of cholecystokinin. In addition, after cholecystectomy, you should eat light and easily digestible food, and do proper physical exercise. It is also important to drink plenty of water and to develop the habit of regular bowel movements. Patients with significant alkaline reflux gastritis should remember to eat small, frequent meals and not to overeat. Also, one should not eat too much meat food for dinner.
