Why does a four-year-old child vomit frequently after eating?

It is not uncommon for children to feel nauseous and vomit after eating. Children's intestines are not fully developed and are relatively fragile, so many gastrointestinal problems can cause nausea and vomiting. When it comes to children's vomiting, every parent must have a scientific understanding and find out the cause so as to provide timely treatment. So, what is the reason for a four-year-old child to vomit frequently after eating?

1. Central nausea and vomiting

1. Nausea and vomiting caused by increased intracranial pressure - seen in craniocerebral trauma, inflammation, tumors, cerebrovascular disease, toxic encephalopathy, etc. Vomiting is projectile and often without nausea.

2. Nausea and vomiting caused by systemic diseases - seen in infections and febrile diseases, metabolic endocrine diseases such as pregnancy, vascular syncope, uremia, hypoglycemia, acute poisoning, hypoxia, ischemia, altitude sickness, radiation reaction, etc.

3. Nausea and vomiting caused by drugs.

2. Reflex nausea and vomiting:

1. Nausea and vomiting caused by digestive system diseases - such as acute and chronic inflammation of the gastrointestinal tract, toxins, mechanical, obstruction, drug and other stimulations, which reflexively cause nausea and vomiting through the vagus nerve of the gastrointestinal mucosa.

2. Inflammation of abdominal viscera such as liver, gallbladder, pancreas, and peritoneum, stimulating the vagus nerve and causing nausea and vomiting, seen in acute and chronic hepatitis, peritonitis, pancreatitis, etc.

3. Throat irritation - artificially induced, pharyngitis, severe cough, sinusitis, denture discomfort, etc.

4. Vestibular vomiting - vomiting caused by motion sickness, vertigo, etc.

3. Neurological functional nausea and vomiting, such as mental nausea and vomiting: It is a conditioned reflex, such as seeing disgusting food or sights, smelling disgusting smells, or due to excessive mental tension, fatigue, strong emotional excitement, etc., which causes nausea or vomiting.

No matter what the reason is for a child to vomit after eating, it will have a great impact on us, so I hope everyone can pay attention to it and find scientific and effective coping methods to help themselves solve the vomiting problem as soon as possible. If there are some gastrointestinal diseases, of course, we need to focus on active treatment.
