Stomach pain in children is actually the same as adult stomach pain. The main reason is that they do not pay attention to their living habits, long time hunger and satiety and irregular diet, or unclean diet; secondly, emotion is also a big factor affecting stomach disease; furthermore, the abdomen is not well warmed, resulting in cold abdomen and gastrointestinal spasm. The pathological manifestation is excessive stomach acid, which corrodes the gastric mucosa and causes stomach pain, burping, acid reflux and belching. It is recommended to eat regularly, quit snacking, avoid oily and spicy food, and avoid eating raw and cold food. In addition to this, attention should be paid to maintaining a good state of mind. In addition, children with frequent stomach pain should also pay attention to whether it is roundworm infection or mesenteric lymphadenitis, which may also manifest as abdominal pain or stomach pain, which requires a hospital laboratory test to look for worm eggs and ultrasound examination to see if it is mesenteric lymphadenitis, and develop a treatment method after diagnosing the cause. If necessary, a gastroscopy should be done, and if the ulcer is formed, or H. pylori infection needs to be treated with regular medication, such as Esomeprazole, Amoxicillin capsules, Clarithromycin and other drugs. In life, children should be allowed to participate in physical exercise, not picky, not partial food, not snacking, to develop good eating habits.
