After bowel cancer surgery, some patients often feel gastrointestinal discomfort such as poor appetite or abdominal distension. For this reason, Tan Jingfan, vice president of Beijing Erlong Road Hospital and deputy chief physician of the Department of Proctology, suggests that drinking yogurt after surgery can relieve the above discomfort. Because the balance of intestinal beneficial flora is broken after intestinal cancer surgery, and drinking yogurt in appropriate amount can help the intestinal flora return to normal. Yogurt contains a lot of lactic acid bacteria and bifidobacteria, which can “reinforce” the number of beneficial flora in the intestine in time. In addition, lactic acid bacteria can break down the lactose in milk to form lactic acid, which makes the intestinal tract tend to be acidic and inhibits the reproduction of spoilage bacteria, removing obstacles for the intestinal tract to absorb nutrients. Meanwhile, bifidobacteria of yogurt will produce acetic acid and lactic acid during the fermentation process, which can effectively inhibit nitrate reducing bacteria and block the formation of carcinogenic substances nitrosamines, and have an anti-cancer effect. For intestinal cancer patients who have poor appetite after surgery, the sweet and sour taste can stimulate taste buds and increase appetite. In addition, yogurt contains high-quality protein, so drinking yogurt can not only replenish beneficial flora but also supplement nutrition. It should be noted that it is better for patients to drink yogurt after meals because the spleen and stomach of tumor patients are weak, and if there is food in the bottom, the spleen and stomach will not be stimulated too much, so that the yogurt can work better. Of course, if the dysbiosis of intestinal flora is more serious and there is long-term abdominal distension and diarrhea obviously, patients should take various microecological preparations to regulate the disorder of intestinal flora under the guidance of doctors. The development of intestinal cancer is closely related to unreasonable diet. In addition to proper consumption of yogurt, patients can also eat fresh vegetables with long fiber, such as celery, cabbage, spinach, etc., to keep the bowel flowing smoothly and avoid deterioration of the disease.
