There are numerous causes of vomiting, but the most common is that associated with any infection, either viral or bacterial, even the common cold. Motion sickness is another cause of vomiting. Vomiting can sometimes occur in association with more serious illnesses such as appendicitis or meningitis.
Projectile vomiting, which is a forceful throwing up of the contents of the stomach, is characteristic of pyloric stenosis. This is a serious condition, and if your child has persistent projectile vomiting you should see your doctor immediately.
Young babies tend to vomit up small amounts of milk after feeds. This is called posseting, and is normal. It can usually be reduced if you burp your baby a little more during feeds.
Vomiting is often accompanied by abdominal pain and diarrhoea.
Dehydration is one of the serious risks of vomiting, especially in young babies.
Medications against vomiting should not be used in children due to the risk of serious side effects. The most important part of the treatment of vomiting is adequate fluid replacement to prevent dehydration.
