The gallbladder has the function of concentrating, storing and emptying bile, thus serving to regulate the pressure in the bile duct. After removal of the gallbladder these functions disappear and the bile secreted by the liver flows continuously into the duodenum, so that during the digestive phase it will appear that the bile flowing into the intestine is insufficient, while during the non-digestive phase the bile flowing into the intestine cannot perform its function. This condition is compensated over time by a compensatory thickening of the bile duct, which partially replaces the gallbladder function, and a persistent and rhythmic closing or opening of the sphincter at the lower end of the common bile duct to adapt to the needs of digestion. Therefore, the poor tolerance of fat digestion in the early post-cholecystectomy period in some patients will gradually improve over time. In fact, there are many patients with preoperative gallbladder that has no function or declined function, and the diseased gallbladder will affect the patient’s digestive function, and biliary colic or acute biliary attack or even cancer will occur, after gallbladder removal in such patients, not only will they not have poor postoperative digestive function, but also improve digestive function and quality of life by removing the diseased gallbladder. A small number of patients may develop bile reflux gastritis after gallbladder removal, which is clinically rare and has a better effect of medication. After cholecystectomy, there may be a short period of discomfort, but after a period of compensation, the patient can work and live normally as usual, and there is no significant impact on human health. Diet after cholecystectomy The diet after cholecystectomy should pay attention to eating less and more meals, the diet should be nutritious, less greasy, appropriate taste and easy to digest. Patients should be encouraged to eat, only when nutrition is added in can the condition recover better and faster. Cholesterol-containing foods should be controlled to reduce cholesterol metabolism disorders, and cholesterol-containing foods such as animal offal, egg yolk, salted duck egg, puffed egg, fish roe and crab yolk should be limited. Should be limited consumption of seaweed, seafood, you can drink some yogurt, you can exercise properly, just after surgery, it is recommended to rest more, the specific cause of pain, you can review and consult your treating doctor. In general, within six months after cholecystectomy, the diet should be light, less oil, high protein (no egg yolk), high calorie-based diet principles, can take a small number of meals, especially should not eat too much animal fat food, such as: fatty meat, pig’s feet. After a period (about half a year) of postoperative period, if the body recovers well, fatty foods can be added in small amounts one by one, so as not to cause abdominal discomfort and diarrhea and other indigestion as the standard. Reasonable dietary arrangements: lightness is the main reason, more coarse fiber food and more water are beneficial to prevent hypertension, hyperlipidemia and habitual constipation. The development of good habits can prevent and effectively control the occurrence and development of many diseases.
