Vomiting could be a part of many illnesses in babies and children. It is not a major concern in general as long as the child is otherwise okay and free from other conditions. Vomiting is considered as common for infants, babies and children. The condition occurs when the food is brought back up from the stomach into the mouth and generally, the content is of stomach.
Many children when become sick lose their appetite in a very drastic way. If this illness then gets accompanied with vomiting, the problem becomes more serious as the body stops getting nourishment. Whatever a child eats is thrown out of the body from the mouth. Vomiting is common but turns to be fatal if left untreated. It vomits out all the contents from stomach, does not allow a child to ingest anything, and thus, cuts off the supply of nutrients into the body.
Vomiting is common and considered as physiological reflex in infants and newborns. The amount may vary from infant to infant. This happens because their digestive system is not well developed and all the time their position is lying down. There is a valve at the various places of digestive track and they are under development in infant’s body. The function of these valves’ is to prevent the backflow of the content to the previous organs of digestive tract. Being in ‘not so developed’ condition, these valves allow the stomach content to flow backwards into the mouth and infants vomits.
In children, the vomiting has to have some underlying cause. Some of the known causes include acidity, indigestion, worms and more likely certain infectious disease involving digestive systems like typhoid, cholera, enteritis etc. The vomiting is looked as a symptom and not as a disease. A child presented with symptoms of nausea or vomiting is investigated for the underlying cause and the treatment is given accordingly.
Some of the dangerous situations in vomiting include bloody vomiting that suggest internal hemorrhage, dark greenish or some abnormal colored vomitus suggest some poison ingestion and vomiting with blood may indicate tuberculosis.
Vomiting itself is a symptom of some underlying cause. However, some signs can be found in a child who is about to vomit include; watering into the mouth, feeling of uncomfortable zone in stomach and chest and some of them feel like a wave from the abdomen to stomach and then to mouth.
Vomiting is a forceful reflex of the body’s digestive system and therefore, all the muscles of abdomen and chest work altogether. The reflex is so powerful that sometimes a victim bends forward to vomit and the episode is indeed troublesome as there will be pain in stomach, abdomen and exhaustion in the entire body. Many of children feel comfortable after vomiting as the irritant particles are removed from the digestive tract, which is the main motto of the body’s defense mechanism. 
Vomiting is however considered as common if and if it is of small quantity and is with less frequency. The moment it contains large amount of the stomach content and it is increased in the frequency (such as twice or thrice in half an hour), it requires immediate medical attention.
The main problem with the profuse vomiting is, it cannot be stopped by taking oral medicines as even medicines are expelled out of the stomach the moment they are taken. The body reflex of vomiting does not allow the medicine to stay and so to work and therefore, ultimately the sufferer is treated with intravenous injections containing anti-vomiting properties.
Other conditions that make doctor to worry is vomiting containing blood, which suggests some internal hemorrhage and vomiting after some head injury. These both are serious problems and need sharp investigations. The victim is to be treated and even after symptoms disappear, an observation for couple of days is must.
The fatal condition occurs when there is a profuse vomiting and when a child becomes dehydrated and addition to this, if vomiting is followed by diarrhea, the case becomes more serious and requires immediate hospitalization. This is due to the loss of important electrolytes in terms of body fluid been lost in both ways; diarrhea and vomiting.
For infants, the burping plays an important role. Burping is the method in which, a newborn is tapped on back gently in a particular way so that all the milk goes down in the stomach and nothing remains in the foodpipe.
For babies and children, the water is to be boiled and then given to prevent the infection that can cause vomiting. The food is not given in abandon quantity and some portion of stomach is left empty by supplying small amount of the food.
For children, frequent eating small amount food is better than having large meals once or twice. There should be a proper gap between two meals or two eating. Vomiting is treated for the underlying causes. For instance, if it is due to infection, the infection is treated first and if it is due to head injury that is treated first.
Medications include syrups, pills, tablets and injections that have antinauseant property or anti-vomiting property. Sometimes antacids do work for the same case. Intravenous fluids are to be supplied in serious cases.
