According to the eating situation, clinical symptoms and necessary laboratory examination data of the sick children, it is judged that the children are functional dyspepsia caused by weakened gastric motility, or dyspeptic symptoms caused by gastritis and peptic ulcer caused by Helicobacter pylori infection. If it is functional dyspepsia caused by weakened gastrointestinal motility, drugs that increase gastric emptying, resist gastric acid or inhibit gastric acid secretion can be selected. If the child has helicobacter pylori infection, it needs to be eradicated.

1. A drug for increasing gastric emptying: metoclopramide, which has a strong central antiemetic effect and can enhance gastric motility. Domperidone (also known as domperidone) can obviously improve the fullness of sick children after meals, and eat less and feel full. Mosapride citrate also has the same effect.

2. Drugs for resisting gastric acid or inhibiting gastric acid secretion: These drugs are widely used in clinic, and have obvious effects on heartburn, acid regurgitation and relieving abdominal pain. Commonly used anti-gastric acid drugs include compound aluminum hydroxide, aluminum magnesium carbonate and calcium carbonate suspension oral liquid. There are two ways to suppress gastric acid. One is H2 receptor antagonists, such as ranitidine, cimetidine, omeprazole and famotidine. There are proton pump inhibitors, such as omeprazole, lansoprazole and rabeprazole.

If it is found that dyspepsia is related to Helicobacter pylori infection, it is necessary to eradicate Helicobacter pylori: the triple therapy of amoxicillin, clarithromycin, metronidazole, bismuth complex, proton pump inhibitor and two antibiotics for 7- 14 days is the best treatment scheme at present.
