The reason why children cry and vomit easily may be due to swallowing a large amount of air, autonomic nervous system dysfunction, and increased abdominal pressure.
1. Swallowing a large amount of air: children will swallow a large amount of air when they cry, and this air may lead to stomach distension and other uncomfortable feelings, and may stimulate the gastrointestinal tract to form a vomit reflex, so they are prone to vomit.
2. Autonomic dysfunction: children often cry because of mental stimulation, and intense crying can lead to sympathetic and parasympathetic nerve function problems, which in turn cause autonomic dysfunction, which can cause gastrointestinal dysfunction, vomiting may occur.
3. Increased abdominal pressure: When a child cries, the respiratory ventilation increases, which can lead to greater respiratory ups and downs, resulting in increased abdominal pressure. And because the child’s stomach is horizontal and the lower sphincter is relaxed, so the increased abdominal pressure will compress the stomach, causing vomiting.
Children cry and vomit easily, there may also be other reasons, it is recommended to go to the hospital, complete the examination to determine the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
