The gallbladder is the place where bile is stored in the body, constantly storing and concentrating the bile secreted by the liver, and during feeding, the gallbladder discharges the concentrated bile into the duodenum by its own contraction to help digest fat. If the gallbladder has to be removed for various reasons, such as cholecystitis, stones, polyps, gallbladder cancer, etc., people will face a change in their physiological state due to unregulated bile. In this case, bile will continue to enter the duodenum, and when people eat, they will not get enough bile to help digestion, resulting in symptoms of indigestion, such as abdominal discomfort, bloating, diarrhea, etc. After surgical removal of the gallbladder, patients can obtain their own regulatory compensation after a period of adjustment and recovery, that is, through compensatory expansion of the bile ducts to effectively maintain the normal physiological functions of the body. The digestive function of the body is relatively weakened at this time. For patients after cholecystectomy, the following points should be noted in home care: (1) Dietary guidance to choose easily digestible food. In the near future after surgery, try to reduce the intake of fat and cholesterol, do not eat or eat less fatty meat, fried food, animal offal, etc. If it is necessary for taste, you can use some olive oil to cook food appropriately. To increase the protein-rich food to meet the body’s metabolic needs, such as lean meat, aquatic products, soy products, etc. Eat more foods rich in dietary fiber and vitamins, such as fresh fruits and vegetables, etc. Develop the habit of eating regularly and in small quantities to adapt to the physiological changes after cholecystectomy. The symptoms of indigestion will last for about six months. As time goes by, the common bile duct will gradually expand and will partially replace the role of the gallbladder, and the symptoms of indigestion will be slowly relieved. At this time, the diet can also be gradually over to normal. (2) Resume normal diet, it is advisable to maintain a low fat, low cholesterol, high protein dietary structure, avoid eating brain, liver, kidney and fried food, moreover, avoid eating fatty meat, avoid drinking alcohol, so as not to affect the function of the liver or cause bile duct stones. (3) Pay attention to mental health, often maintain emotional stability, optimism and open-mindedness, avoid anger, anxiety, depression and other adverse emotions, in order to prevent disorders of the central nervous and plant nerve regulation, affecting the recovery of bile duct compensatory function. (4) Appropriate participation in physical exercise and light physical labor, avoid prolonged sitting and lying, too little activity, in order to facilitate the recovery of muscle function. Within two to three months after surgery, you can do activities such as walking to promote the recovery of the body. (5) Regular review Take the medication as prescribed by the doctor and visit the hospital regularly for follow-up consultation in case of discomfort.
