Gastrectomy for cardia cancer has certain effects on eating and absorption of nutrition. 1. Impact on eating: since stomach has the function of storing food and initially digesting food, you cannot eat as before after gastrectomy. After gastrectomy for cardia cancer, the stomach becomes smaller, or all stomachs are removed leading to direct connection between esophagus and small intestine, so it is suggested that you can’t eat too much at one time, and if you eat too much every time and can’t digest it or directly dilate the small intestine, it may cause abdominal discomfort. 2. Influence of nutritional absorption: after gastrectomy, the volume of stomach is reduced, and the absorption of food nutrients is also affected, so it is necessary to pay attention to increasing food with high vitamin content, such as animal offal and carrot, etc., and don’t eat stimulating and not easy-to-digest food in daily meals. After gastrectomy for cardia cancer, one should go to the hospital regularly for postoperative rechecking, and can have a reasonable diet under the doctor’s advice to avoid adverse consequences.
