What is the reason for a 4-year-old child with low fever and vomiting yellow fluid?

Patient's question:

No

Doctor's answer:

Hello, general gastritis is mostly caused by Helicobacter pylori infection. It can be treated with triple therapy, such as metronidazole tablets, omeprazole, and amoxicillin capsules. Generally, the treatment lasts for two to three weeks. At the same time, it is important to avoid smoking, alcohol, and staying up late. Do not eat spicy and irritating foods, and keeping warm is also very important.
