In recent years, with the widespread popularization of endoscopic technology, gastroscopy detected children suffering from peptic ulcer, gastritis and other gastric diseases is not uncommon, what’s more, our hospital had detected the smallest only 14-year-old gastric cancer patients, adult diseases, children’s gastric disease at an early age do not take it lightly, it is worthwhile to attract the attention of clinicians. Children are in the stage of growth and development, just as “the rising sun of the square rise, grass and trees of the square bud”; once suffering from chronic gastric disease often lead to children malnutrition, anemia, physical weakness, and even secondary other diseases. Diet is not regular, Helicobacter pylori infection, learning pressure is the main reason for the development of children’s gastric disease and gastric ulcer. 1, the diet can not be no regular diet structure is not scientific, diet is not regular is triggered by children’s stomach disease and gastric ulcer of the main external causes. Now living conditions are better, a variety of snacks are also more, due to eating irregularly, excessive secretion of gastric acid; poor hygiene habits, easy to cause Helicobacter pylori infection (HP positive), some families will also occur within the Helicobacter pylori infection phenomenon of aggregation. HP can pass through the human gastric mucosa, causing active gastritis, gastroduodenal ulcers, and may even cause severe gastrointestinal hemorrhage. 2, too much pressure triggered stomach pain Another external cause of pediatric gastropathy and gastric ulcers is the environment and mental stress. Stress leads to vegetative nervous system dysfunction, neuroendocrine dysfunction, often in the past, there can be gastric acid secretion can be high, gastrointestinal emptying function is weakened, so there can be abdominal or umbilical cord around the hidden pain discomfort, nausea, vomiting, abdominal distension, vomiting, anorexia, constipation and so on. Meet the climate seasonal changes and the eve of the examination, this kind of stomach pain caused by excessive pressure is more common. 3, pediatric gastropathy can be prevented and treated gastropathy is a chronic digestive disease, can be prevented and treated. In the diet to: pay attention to dietary hygiene, develop good eating habits; children’s breakfast should pay attention to, three meals reasonably arranged, do not too hungry, too full, life should be regular; snacks and drinks, especially cold drinks and so on should be moderate; do not partiality, do not picky about food. Secondly, in the study should be open, do not always be in a tense state of pressure, strengthen the exercise, enhance physical fitness. The last thing to note is that if there is abdominal pain, bloating, acid reflux, poor appetite, lethargy and other symptoms, do not simply think that it is caused by intestinal worms, it is best to go to the hospital for further examination, if necessary, can do electronic gastroscopy. As long as the diagnosis is clear, whether it is gastric ulcer or gastritis, can be cured by conservative treatment.
