First of all, relax mentally and don’t put too much pressure on your child in studying. Give your child enough sleep and pay attention to the cold and warmth. In terms of diet, at the beginning of treatment, children should eat easily digestible and less stimulating food, such as thin rice or softer rice. Eat less and more meals, eat regularly, eat less cold drinks, candy, fried food; avoid drinks containing carbonates or alcohol, strong tea, coffee, spicy and sour condiments, etc. Be cautious with drugs that have damaging effects on the gastric mucosa, such as aspirin. If the child has repeated vomiting, vomiting blood, black stool or anemia, wasting performance, gastroduodenal X-ray barium meal examination should be made, and gastroscopy should be made when available to make a clear diagnosis, meanwhile, it is better to make H. pylori examination before treatment. At present, the drugs for the treatment of peptic ulcer have good efficacy, and it can be completely cured by mainly adhering to the regular treatment. Can choose 2-3 of the following types of therapeutic drugs in combination, if there is H. pylori infection, but also anti-H. pylori treatment. 1, inhibit stomach acid drugs: this is the main drug for the treatment of peptic ulcer. Including H2 receptor antagonists and proton pump inhibitors. The former, such as cimetidine 10-15mg/kg.day in 2 times/day, ranitidine 3-5mg/kg.day in 2 times/day, famotidine 0.9mg/kg.day in 2 times/day. The latter is mainly used in children with omeprazole 0.7mg/kg.day in 1 dose/day. Second generation proton pump inhibitors such as rabeprazole and esomeprazole should be used with caution as there is no information on their use in children. The course of treatment is 4-6 weeks for duodenal bulb ulcers, 12 weeks for post bulb ulcers, and 6-8 weeks for gastric ulcers. 2, neutralize the stomach acid drugs: commonly used aluminum hydroxide and aluminum magnesium carbonate and its compound preparations, such drugs can quickly control the symptoms. 3.Protective drugs for gastric mucosa: commonly used are aluminum thioglycollate 10-25mg/kg.day, divided into 3 times/day, colloidal bismuth 6-8mg/kg.day, divided into 2 times/day, but bismuth has damage to the nervous system and renal function, and cannot be applied for a long time. 4, eradication of H. pylori treatment: if there is H. pylori infection, a proton pump inhibitor (such as omeprazole) and two antibiotics sensitive to H. pylori can be used in a triple therapy, shared 1 week course, antibiotics are metronidazole 25-30mg/kg.day, divided into 2 times / day, clarithromycin 15-30mg/kg.day, divided into 2 times / day, hydroxybenzyl penicillin 50mg /kg.day in 2 doses/day (for those without penicillin allergy). This is very important for the eradication of ball ulcers and prevention of recurrence and complications. After 1 month of drug discontinuation, it is important to review whether H. pylori is eradicated. 5. In rare cases, surgical treatment is required: massive bleeding that is ineffective with medication or endoscopic treatment; acute gastric or duodenal perforation; scarring pyloric obstruction that fails with balloon dilation.
