The movement of the esophagus and gastrointestinal tract, including peristalsis and secretion, is regular and sequential. A regular diet is conducive to the regular activity of the autonomic nervous system that maintains normal peristalsis and secretion of the esophagus and gastrointestinal tract, while when the diet is irregular, such as a diet that is not regular and quantitative, a hungry meal, a full meal, etc., it will naturally cause dysfunction in the movement and secretion of the digestive tract, leading to the production of corresponding gastrointestinal diseases. Clinically, we often see that the incidence of gastrointestinal diseases varies depending on the occupation and type of work. Generally speaking, the incidence of esophageal and gastrointestinal diseases is significantly higher among busy people engaged in business, IT, drivers, purchasing, sales, coaching, medical care, etc., who cannot eat on time due to irregular life. Therefore, the prevention and control of reflux disease esophagitis, we must pay attention to the diet. First of all, eating needs to be chewed slowly, so that the food in the mouth fully chewed. On the one hand, chewing can make food and saliva fully mixed, conducive to the formation of fine food mass, easy to enter the gastrointestinal through the esophagus, and also easy to be digested and absorbed; on the other hand, full chewing can reflexively stimulate the vagus nerve center, so that the gastrointestinal fluid secretion, promote the gastrointestinal tract orderly peristalsis, conducive to the digestion and absorption of food. If the food is not fully and carefully chewed, in the process of coarse food mass through the esophagus into the gastric cavity, can produce mechanical stimulation of the esophagus and gastric mucosa, and difficult to digest and absorb, in the long run, the doctor suffered from gastroesophageal reflux disease. Secondly, eating needs to be even, slow, and avoid rushing to eat. Rush eating on the one hand, the food will not be fully chewed, on the other hand, will therefore eat too much, too full, which is easy to cause acute gastric dilatation, indigestion, acute and chronic gastritis, etc.. This is because the human brain has a satiety center in charge of controlling the amount of people eating, within a certain period of time, adequate chewing and stomach cavity gradually tolerable expansion, can stimulate the satiety center, when the stimulation reaches a certain level, the satiety center will issue instructions, so that people produce the feeling of “full”, and then stop eating. If you eat too fast, in the information has not been transmitted to the brain, the satiety center is too late to issue the “full” command, the stomach cavity has been filled with food full, to feel full when, have eaten too much. In addition, do not add a meal before bedtime to prevent aggravation of symptoms. Attention should also be paid to less snacking. Often snacking. Will disrupt the normal digestive pattern of the gastrointestinal tract, so that the gastrointestinal fluid secretion and gastrointestinal peristaltic function disorder, not only affect the digestion and absorption of food, but also increase the gastrointestinal burden. In addition to diet, we should also pay attention to the following 4 points. (1) The head of the bed should be raised 12-20cm during sleep, and avoid lying in bed immediately after meals, or drinking and eating before bed. (2) Obese people should reduce their weight, do not wear tight-fitting clothes and pants, and should minimize activities that increase intra-abdominal pressure, such as avoiding bending, heavy physical labor and stool height force. (3) Avoid smoking and drinking alcohol. Nicotine in cigarettes can reduce the pressure of the lower esophageal sphincter at rest, and wine can also reduce the pressure of the lower esophageal sphincter at rest. (4) Do not eat chocolate, because chocolate contains a large amount of xanthine, which is a strong inhibitor of intracellular diphosphodiesterase, which can increase the concentration of adenosine cyclic phosphate in the smooth muscle receptors of the lower esophageal sphincter and reduce its pressure. Avoid ingesting substances that are stomach acid-increasing, such as coffee, spicy foods and acidic beverages.
