As the saying goes, disease enters through the mouth, diet, has always been a topic of our concern, we need to pay more attention to the occurrence of esophageal cancer in our daily life. With the increasing chance of this disease appearing, it has to make us pay more attention to it. In our daily life, many patients have difficulty in swallowing, which has seriously affected their health. For us, we should pay attention to the occurrence of esophageal cancer in our daily life, and those who have esophageal cancer should pay more attention to the diet after surgery. 1.What are the early symptoms of esophageal cancer? First of all, if you are a beer drinker, you should not only pay attention to controlling the amount of alcohol consumed, but also pay attention to the small changes in your body, so as not to let esophageal cancer come to your doorstep. The following are some common early symptoms of esophageal cancer: 1. Hoarseness: when the tumor directly invades or the metastatic foci compress the recurrent laryngeal nerve, there is paralysis of the vocal cord, resulting in hoarseness, and a part of the patients can be better due to effective treatment of hoarseness. This is one of the symptoms of esophageal cancer. 2. Spitting mucus: incomplete or complete obstruction of esophagus caused by esophageal lesion, which makes secretion drainage not smooth, accumulates in the upper part of esophageal stenosis, and stimulates esophagus to spit out after retrograde peristaltic movement. Difficulty in swallowing: Progressive difficulty in swallowing is the most typical symptom of middle or advanced esophageal cancer, which starts from solid food cannot be swallowed smoothly, or can be swallowed after rinsing with soup and water, and then semi-fluid diet is also blocked, and finally there is difficulty in swallowing fluid diet. The degree of unfavorable swallowing is closely related to the type of pathology, narrowing type and medullary type are more serious. 4.Dry cough: If the trachea is compressed, there may be shortness of breath and dry cough, and if an esophageal fistula is formed, choking on food occurs. Lump in neck and supraclavicular region: it is a common sign of advanced esophageal cancer. The lump is painless, progressive and hard, mostly on the left side, but also on both sides. Bleeding: necrosis, ulceration or invasion of cancer tissues and blood vessels may cause vomiting of blood or black stool, and when the tumor invades the aorta, it may cause hemorrhage and death. There are many reasons for esophageal cancer patients to have difficulty in eating after surgery, such as spasm of esophagus or incomplete local absorption after eating, and possible edema of anastomosis, but there is no need to worry too much about these cases, which can be recovered after a period of time of repairing and patients’ adaptation. However, if these symptoms persist or become more severe after 3 months, the patient should go to the hospital for a checkup to identify the problem. Common problems are anastomotic stenosis or local recurrence of the tumor. In the former case, balloon dilatation or stenting can be done to improve the symptoms; in the latter case, radiotherapy or chemotherapy is needed. Compared with the above problems, patients and their family members are more concerned about nutritional supplementation after surgery, so dietary regulation for esophageal cancer patients after surgery is particularly important. Proper diet can speed up the postoperative recovery of patients, on the contrary, it may cause discomfort, and the dietary regulation of esophageal cancer patients will be explained below. The diet of postoperative esophageal cancer patients is “slow”! Not only the speed of eating should be slowed down, but also the structure of diet should be gradual according to the patient’s condition, firstly, nasal feeding nutritional liquid, then fluid, semi-fluid, and then general food, in a gradual and orderly manner, none of which should be done in a sloppy manner. Patients usually have difficulty in swallowing in their diet, so they should eat slowly, chewing, meat and vegetables, and must avoid eating too fast, too hard, too coarse and too hot and other bad habits. As the patient’s vagus nerve is cut off during the operation, there is no feeling of saturation and hunger after the operation, so the patient’s diet should pay attention to small meals, don’t wait until the time of hunger, depending on the situation, usually eat 6-7 times a day. Secondly, the postoperative diet should be reasonably matched to restore the patient’s physical strength and immunity as soon as possible. Appropriate Chinese medicine can help the patient’s immunity recovery, Cordyceps sinensis, birch mushrooms, poria mushroom, Ming Dangshen, Qing Yang Ginseng and so on are all good choices.
