Children with constant hiccups are usually seen in the following conditions: First, diaphragmatic spasm is relatively common, and increased excitability of the phrenic nerve due to various causes can lead to repeated hiccups. Second, note that the child is likely to have an acute attack of chronic gastritis caused by Helicobacter pylori infection, or may have a gastric ulcer, etc. Third, also note that some children have improper diet, poor digestion, and a significant increase in gas accumulation in the gastrointestinal tract after eating, which can also cause hiccups. Fourth, infectious diseases, especially infections of the gastrointestinal tract, such as intestinal viral infections or bacterial infections of enteritis and gastritis, which cause nausea, vomiting and hiccups, are also more common clinically. Fifth, some children’s intestinal micro-ecosystem is out of balance, probiotics are reduced, and gas accumulation in the gastrointestinal tract increases, which can also lead to hiccups.
