On the third day after esophageal cancer cardia surgery, we started to give the patients fluids by nasal feeding tube, commonly used are milk, soy milk, millet soup, meat soup, fish soup and so on. So that after discharge, milk is still the most popular because of its high nutritional value, convenience and ease of use. However, in clinical observation, it is true that a small number of patients are not suitable for drinking cow’s milk products, which is due to the lactose intolerance of this group of people. After drinking milk, the lighter the abdominal rise, heartburn, acid reflux. In severe cases, vomiting and abdominal pain. For this type of patients, we should not use milk products, can be used soy milk powder, broth rice porridge millet porridge eggs such as grain-based food instead, completely fine. Including the diet after discharge, also do not use dairy products. This is an individual difference, and everything should not be forced. And those patients who can drink milk, half a catty of fresh milk per day is definitely good for the body. In general, the supply of nutrition should be different from person to person and it is better to go with the flow.
