What should I do if the baby often vomits?

Patient's question:

My son is now two weeks and eight months old. He has been vomiting frequently since he was one or two months old, usually when eating or drinking. What could be the reason? What should parents do? Thank you

Doctor's answer:

Vomiting is a common symptom in children's lives. Severe vomiting can lead to dehydration, electrolyte disorders, and there are many causes of vomiting. For example:
??1. Improper feeding, excessive feeding or rapid swallowing causing air to be inhaled;
??2. Childhood gastroenteritis causing intestinal dysfunction and leading to vomiting;
??3. Relaxation of the upper part of the stomach (called the cardia) can cause spitting up;
??4. Infectious diseases such as encephalitis, pneumonia, etc.;
??5. Neurological diseases such as hydrocephalus, cerebral edema, and intracranial hemorrhage;
??6. Esophageal atresia;
??7. Hypertrophy of the lower part of the stomach (called the pylorus) causing the stomach contents to flow downward and resulting in vomiting, often occurring 2 to 3 weeks after birth and appearing as projectile vomiting;
??8. Bowel obstruction, such as intestinal obstruction, intussusception, small intestinal stenosis or atresia, intestinal volvulus, etc.;
??9. Megacolon, anorectal atresia, or anal stenosis, with initial constipation and abdominal distension, vomiting appearing later;
??10. Other causes such as acute poisoning, medication, pyloric spasm, motion sickness, seasickness, etc., can also cause vomiting.
??Some of the vomiting may be normal physiological phenomena, which will gradually stop with a bit of attention, while others are caused by serious diseases and require timely treatment. Therefore, if a child vomits, it should not be taken lightly. It is important to seek medical attention promptly to confirm the diagnosis and receive timely and appropriate treatment.
