Gastrointestinal dysfunction is a common gastrointestinal disease, and its development is often closely related to motor disorders, visceral hypersensitivity, altered intestinal flora, and the presence of psycho-social-physiological factors. Genetic factors exist in some patients, and environment is also an important factor, such as heavy workload, increased financial burden, fierce competition at work, too fast pace of life, layoffs and unemployment, death of relatives, stimulation from accidents, interpersonal tension and family disputes. Food factors such as sour fruits, spices, alcohol, chili peppers and strong coffee are also triggers of the disease. Therefore, in addition to medication and attention to psychological adjustment, dietary conditioning is very important for this disease. Since the symptoms of gastrointestinal disorders are diverse and cover basically all gastrointestinal symptoms, such as nausea, vomiting, belching, abdominal pain, bloating, diarrhea, and constipation, the treatment is mainly symptomatic, preventing the onset of symptoms and avoiding triggering factors. There are different dietary contraindications for different symptoms. Common symptoms of dietary contraindications are as follows: 1, abdominal pain dietary contraindications 1, spicy food: spicy food can improve appetite, but the stimulation of the body, especially the gastrointestinal, esophageal irritation is very large, abdominal pain patients must not eat spicy food again during the period of illness and pain, so as not to increase the burden on the gastrointestinal, gastroesophageal damage, aggravating the pain. 2, fried food: fat content is very high fried food should not be eaten during abdominal pain. Because the fat content of the food is very difficult to digest, will be through the secretion of excessive gastric acid on the stomach to produce a lot of stimulation to promote transport, which is already abdominal pain patients is undoubtedly adding insult to injury. 3, sour, sweet food: abdominal pain patients should also avoid eating too sour or too sweet food, because sour food will accelerate the secretion of gastric acid, and even cause acid reflux, resulting in stomach pain. The food containing fructose, especially fructose in soft drinks and beverages is difficult to absorb, will bring burden to the stomach and intestines, and chocolate high-calorie sweets are the same, will increase the burden on the stomach and intestines, and can not play a role in relieving the effect of abdominal pain, but easily intensified. Second, diarrhea diet taboos 1, coarse fiber food: during diarrhea, for some fruits and vegetables rich in coarse fiber should be avoided as much as possible to avoid the situation of diarrhea intensified. For example, like pineapple, grapefruit, lemon, mandarin, spinach, cabbage, bamboo shoots, wild rice, etc., these foods are rich in fiber, these fibers can promote intestinal peristalsis, so that your diarrhea is more uncontrolled. 2, flatulent food: there are many foods that cause flatulence in life, such as milk, after consumption in the intestines will lead to flatulence so should not eat. This type of food will lead to increased intestinal peristalsis, once the intestinal flatulence will make the diarrhea intensify. During diarrhea can not eat legumes, whether soybeans, adzuki beans or mung beans, such foods contain coarse fiber and rich protein, this time to eat then will cause intestinal peristalsis to increase and cause flatulence, and intensify diarrhea. 4, high-fat food: try to eat less fatty foods, such as fat, lard, butter, lamb fat, cream, etc.. In these foods contain a lot of fat, which can aggravate diarrhea, leading to slippery intestines, prolonged diarrhea. And patients in the period of illness, it is best to use vegetable oil to cook vegetables, and the amount of oil is not too large, because the amount of vegetable oil can cause diarrhea. Third, constipation diet taboo 1, easy flatulence, indigestible food: common sweet potatoes, potatoes, onions and other foods, these foods will produce gastrointestinal distention after eating, aggravating constipation patients bloating, abdominal pain symptoms. 2, astringent food: common persimmons, lotus seeds, sorghum, pomegranate, etc., because these foods are more astringent solid astringent, constipation patients can make intestinal peristalsis weakened after ingestion, the stool is difficult to discharge. 3, stimulating drinks: because all kinds of alcohol, coffee are warm nature, these can be depleted intestinal fluids. Resulting in dry stool, aggravating constipation; and tannic acid contained in tea has an astringent effect, can make intestinal peristalsis weakened, the stool is difficult to discharge. 4, too fine food: if meat, eggs, milk, etc. eat too much, and coarse grains, vegetables and other plant fiber eaten too little, as well as insufficient water, will lead to intestinal food residues on the intestinal wall of mechanical stimulation is reduced, not enough to cause defecation reflex. Of course, the best doctor is yourself, and if you eat which foods tend to induce symptoms, it is best to prohibit them.
