Vomiting can be part of many illnesses in children and babies. It is not usually a major concern as long as your child seems well in other ways.

Vomiting is common for babies and young children. Vomiting occurs when food is brought back up from the stomach. The amount of vomit can often seem larger than it actually is.

Types of vomiting

There are different types of vomiting, including:

Possetting – this is when your baby vomits up small amounts after a feed.
Reflux – this vomiting is common in babies. It is caused when the valve at the top of the stomach accidentally opens. The contents of the stomach come back up the food pipe (oesophagus) slowly. Reflux does not harm babies. They usually grow out of it by the time they are walking.
Projectile vomiting – this is when your baby brings up the stomach contents in a forceful way. The amount of milk or food can seem large on the floor, but is usually only the amount of the last feed. Babies may projectile vomit occasionally, but if it happens after every feed, see your doctor right away as it may be due to a blockage caused by thickening of the muscle at the outlet of the stomach.

Causes of vomiting

Vomiting is usually caused by:

minor infections like 'gastro' or the common cold
gastro-oesophageal reflux
motion sickness from travelling in a moving vehicle.

Sometimes, vomiting may be part of a more serious illness. Children may vomit if they have an infection, such as a urinary tract infection or meningitis, a bowel obstruction or appendicitis. If vomiting progresses to fever and diarrhoea, it will usually be caused by a virus infection. If this persists for 12 hours or more, dehydration is likely. so see your doctor or local hospital emergency department without delay.

Treatment for vomiting

Most babies and children vomit easily and recover quickly. After vomiting, your child may be hungry and thirsty. Give plenty to drink so your child does not become dehydrated. If your child keeps on vomiting and looks unwell, see your doctor. Do not use medication to try and stop the vomiting.

Reflux vomiting can be prevented or reduced

Different positions for feeding or in bed can help reduce your baby’s chance of vomiting. You can try to:

Feed your baby in an upright position.
Prop your baby up after feeds.
Lay your baby on the left side.
Avoid bouncing your baby after feeding.

To help with mild reflux, you can thicken your baby’s food with cornflour or infant food thickener. If your child is uncomfortable after vomiting or will not settle, try giving milk or water. This will wash any acid back into the stomach. Some babies get heartburn, which is a burning sensation in the chest. They may be unsettled after feeding or when lying flat. Your doctor can suggest an antacid to relieve heartburn.

When to see your doctor

Take your baby to the doctor if any of these symptoms occur:

poor weight gain because of the loss of feeds in vomiting
coughing or choking spells
blood or yellow-green bile in the vomit
heartburn
vomiting increases or becomes forceful after every feed
your baby seems unwell.

Baby Vomiting After Feeding Formula: Causes and Treatment

Your little one is happily gulping their formula while cooing at you. They finish off the bottle in no time flat. But shortly after feeding, it seems to all come out as they vomit.

There are several reasons why your baby might be vomiting after a formula feeding, but it’s important to remember that it can be — and often is — very normal.

It’s common for babies to throw up sometimes after feeding on formula or breast milk. Their shiny new digestive systems are still learning what to do with all the yummy milk coming down into their tummy.

However, if your baby often has a hard time keeping their formula down on a regular and frequent basis, let your pediatrician know.

Having a baby around means getting used to soft mushy stuff coming out fairly often. This includes spit-up and vomit.

Spit-up and vomit might seem pretty much the same — and require similar amounts of cleaning to get them off of your sweater and the sofa — but they’re very different. Spitting up is an easy, gentle dribble of milk. Baby may even smile at you as the curd-like spit-up flows from their mouth.

Spit-up is normal in healthy babies, especially if they’re under the age of 1.

On the other hand, vomit takes more effort, as it comes from deeper in your little one’s stomach. It’s a sign that your baby’s stomach is saying nope, not now, please. You might see your baby strain and recoil just before they projectile vomit. This force happens because vomit is squeezed out by the stomach muscles.

Your baby might also look more uncomfortable during and after vomiting. And vomit looks and smells different. This is because it’s usually formula, breast milk, or food (if your baby is eating solids) mixed with stomach juices.

If you’re not sure whether your baby is vomiting or spitting up, look for other vomiting symptoms, like:

crying
gagging
retching
turning red
arching their back

That said, there doesn’t seem to be agreed-upon definitions of these two terms among healthcare providers, caregivers, and others. Plus, their symptoms may overlap. For example, spitting up may sometimes be forceful, and vomiting may sometimes seem painless.

Overfeeding

It’s easier for your baby to overfeed when they’re drinking from a bottle than when they’re breastfeeding. They can also gulp down milk faster from a bottle and rubber nipple. What’s more, because formula is always available, it’s easier for you to give them more milk than they need by accident.

Babies have tiny stomachs. A 4- to 5-week-old infant can only hold about 3 to 4 ounces in their tummy at a time. This is why they need lots of smaller feedings. Drinking too much formula (or breast milk) in one feeding can overfill your baby’s stomach, and it can only come out one way — vomit.

Not burping properly

Some babies need to be burped after every feeding because they swallow lots of air as they gulp down milk. Bottle feeding your baby breast milk or formula may lead to more air-swallowing, as they can gulp even faster.

Too much air in the stomach can make your baby uncomfortable or bloated and trigger vomiting. Burping your baby right after feeding them formula may help prevent this.

To help prevent your baby from swallowing too much air and vomiting after formula feeding, check your baby’s bottle. Make sure you’re using a smaller bottle that’s just big enough to hold a few ounces of milk. Also, check to make sure the nipple hole is not too big, and don’t let your baby continue gulping when the bottle is empty.

Baby or infant reflux

Baby can have acid reflux, indigestion, or occasionally gastroesophageal reflux disease (GERD just like grown-ups! This happens because their stomach and food tubes are still getting used to holding down milk.

Baby reflux happens when milk travels back up toward your baby’s throat and mouth. This usually just causes some painless spitting up, but it can irritate your baby’s throat and trigger gagging and vomiting.

Sometimes, smaller feedings can help prevent baby reflux. If not, don’t worry! Most little ones outgrow baby reflux by the time they’re 1 year old.

Constipation

While simple constipation would be an uncommon cause of vomiting in an otherwise healthy infant, sometimes baby vomiting happens because of what isn’t happening at the other end.

Most babies who are formula-fed need to poop at least once a day. Anything less than your baby’s typical pattern, though, might indicate they’re constipated.

If your baby is vomiting after a formula feeding, they might be constipated if they have other symptoms, including:

gassiness
not pooping for longer than 3–4 days
a swollen or bloated stomach
a firm or hard stomach
crying bouts or irritableness
straining very hard but not pooping or pooping only a little
small, hard pellet-like poop
dry, dark poop

Stomach bug

If your baby doesn’t usually vomit after having formula, they might have a stomach bug. Also known as gastroenteritis or the “stomach flu,” a stomach bug is a very common cause of vomiting in babies. Your little one may vomit several times for up to 24 hours.

Other symptoms of a stomach bug include:

crying
stomach cramps
stomach rumbling
bloating
diarrhea or watery poop
mild fever (or none at all in babies)

Allergy

In rare cases, the cause of your baby’s vomiting might be in the formula. Although it’s uncommon for babies to be allergic to cow’s milk, it may happen to up to 7 percent of babies under the age of 1.

Most children outgrow a milk allergy by the time they’re 5 years old, but it can cause vomiting and other symptoms in babies. A cow’s milk allergy might cause vomiting right after your baby eats. It can also cause vomiting and other symptoms hours or rarely days later.

If your baby has an allergy to milk or something else, they might have other symptoms of an allergic reaction, like:

skin rash (eczema)
diarrhea
cough
hives
difficulty breathing
wheezing

Lactose intolerance

An allergy to milk is different than being lactose intolerant. Lactose intolerance usually causes digestive symptoms like diarrhea. It can also make your baby vomit after drinking formula containing cow’s milk.

Your baby might get temporary lactose intolerance after getting a tummy bug or gastroenteritis, although this is uncommon.

Other symptoms include:

diarrhea or watery poops
constipation
bloating
gassiness
stomach pain
stomach rumbling

Note that lactose intolerance is rare in babies under the age of 1.

Other causes

Some common health conditions can cause vomiting at any time, including after breastfeeding or formula feeding. Some rare genetic conditions can also cause vomiting in babies.

Other causes of vomiting in babies include:

colds and the flu
ear infections
some medications
overheating
motion sickness
galactosemia
pyloric stenosis
intussusception

In most cases, minor tweaks can help stop your baby’s vomiting. Remedies to stop your baby’s vomiting after formula depend on what’s causing it. Try some of these tried and tested methods to see what helps your baby:

feed your baby smaller amounts of formula more often
feed your baby slowly
burp your baby after the feeding
hold your baby’s head and chest up while feeding
hold your baby upright after a feeding
make sure your baby doesn’t move around or play too much right after a feeding
try a smaller bottle and smaller-hole nipple to feed
check the ingredient list on your baby’s formula
ask your baby’s doctor if you should try a different kind of formula
talk to your baby’s doctor about a possible allergic reaction
dress your baby in looser clothing
make sure their diaper isn’t on too tightly

If your baby has the stomach flu, you’ll both usually just have to ride it out for a day or two. Most babies and children with a stomach bug don’t need treatment.

If your baby is vomiting, see your doctor or pediatrician right away if they:

are vomiting often
are vomiting forcefully
aren’t gaining weight
are losing weight
have a skin rash
are unusually sleepy or weak
have blood in their vomit
have green bile in their vomit

Also, see your doctor urgently if your baby has any sign of dehydration from all the vomiting:

dry mouth
crying without shedding tears
a weak or quiet cry
floppiness when picked up
no wet diapers for 8 to 12 hours

It’s pretty common for babies to vomit, especially after feeding. This happens for many reasons, including that these little people are still just getting used to keeping down their milk.

Check with your doctor about what you can do. See your doctor urgently if your baby vomits often for any reason.

Article | Neurotic vomiting in children

Bobylova M. Yu. (neurologist)

Vomiting in children is not an independent disease, but a manifestation of various diseases. Vomiting can be caused by disorders of the gastrointestinal tract, metabolic diseases, tonsillitis, inflammation of the nasopharynx, pneumonia, influenza, SARS, acute appendicitis. Such vomiting is treated by a pediatrician. But there are also vomiting associated with dysfunction of the central nervous system. It develops in children of the first months of life who have undergone hypoxia during fetal development or childbirth. After 6 months, habitual vomiting is often associated with improper introduction of complementary foods if the child is force fed. Also, vomiting can be a sign of increased intracranial pressure. Vomiting attacks are characteristic of the childhood form of migraine.

In infants , especially in the first 3 months of life, regurgitation of a small amount of food (15-30 ml) 2-3 times a day is a common phenomenon that disappears with the growth of the child. The horizontal position of the baby and the relatively large amount of food predispose to the occurrence of regurgitation in healthy infants. It is also characteristic of regurgitation when swallowing air during breastfeeding, when there is not enough breast milk in the mammary gland, or when the baby does not capture the areola. With artificial feeding - swallowing of air occurs when the nipple is not completely filled with milk, when there is a large hole in the nipple, when the position of the bottle during artificial feeding is horizontal.

Swallowing air is more common in infants who are hyperexcitable, greedily sucking, and also with general muscular hypotension.

Regurgitation, unlike vomiting, occurs suddenly, does not affect the behavior and general well-being of the child, while children do not lose weight gain.

Helping a child with spitting up: firstly, immediately after feeding and during sleep, you should hold the baby in an upright position. If regurgitation has occurred, it is necessary to turn the child's head to one side, toilet the child's nose and mouth (clean it from food debris). Wash and caress the baby.

Feeding rules must be observed: the baby should be fed in a semi-vertical position, which helps to expel swallowed air. These babies should sleep with their heads up.

If regurgitation is frequent and profuse, and the baby begins to lag behind in weight, then this may be a manifestation of a disease of the stomach or intestines (pylorospasm or pylostenosis). It is necessary to contact a pediatrician for timely examination, diagnosis, treatment and prevention of complications.

Neurological disorders as a cause of vomiting in a child

The vomiting center of a person is located in the brain, therefore, in case of any damage to the head (trauma, infection, vegetative-vascular dystonia, increased intracranial pressure), vomiting occurs not associated with food intake and fever .

Vomiting in children under 1 year of age is associated with hypoxia during fetal development and at birth.

Neurotic vomiting develops as a manifestation of neurotic reactions in response to nasty and undesirable actions: coercion, protest against punishment, feeding. Functional vomiting in such children is more often combined with refusal to eat, with selectivity in food, behavioral changes, and stubbornness. More common is functional vomiting in children who are emotional, easily excitable, vulnerable. There are no signs of intoxication of the body, pain in the stomach, diarrhea or temperature in the child. This behavior requires prompt treatment to a neurologist.

Vomiting in children, even if it is not accompanied by diarrhea and fever, requires the attention of parents. In no case should you self-medicate, since for each disease the methods of treatment are different.
Only a doctor can recognize the causes of the problem after a series of examinations. To clarify the cause of constant vomiting in a child, it is necessary to clarify when it began, what kind of character it is (periodic, after each feeding), whether it is somehow connected with food intake and with the time of day. Important information about possible diseases is also provided by the diagnosis of vomit. The masses are checked for the presence of mucus, bile, milk, blood, digested and undigested food debris. When making a diagnosis, the age of the child is taken into account. If in infants and young children, in most cases, vomiting is a symptom of CNS disorders due to asphyxia (intrauterine or postpartum), trauma, defects in the gastrointestinal tract, and intolerance to cow's milk, then in older children it is a sign of a possible migraine.
Diagnostic procedures in determining the cause include ultrasound of the abdominal cavity, blood, feces, examination by a neurologist, if necessary, tomography, EEG, neurosonography. In the complex treatment of vomiting, sessions with a psychologist are important.

Help with neurotic vomiting includes a wide range of preventive and therapeutic measures that require an integrated approach.

Required tasks:

1) elimination of emotional disorders (emotional lability, irritability, anxiety, etc.;

2) treatment of asthenic manifestations, overcoming physical and mental exhaustion;

3) regulation of autonomic disorders;

4) treatment of obsessions and fears, if any;

5) correction of personality traits;

6) elimination of negative factors;

Regurgitation and vomiting in children

The regurgitation syndrome is one of the most common reasons for parents of small children to visit a pediatrician and a surgeon. The causes of regurgitation in children under 1 year old are different: anatomical and functional features, neurological disorders, infectious processes, malformations or other problems. The mechanism that prevents regurgitation and vomiting in children is very complex and depends on the anatomical structure and physiological processes of the child. The formation of this mechanism occurs in the last trimester of pregnancy and continues in the first months of a child's life. Although regurgitation and vomiting can be a symptom of various diseases, in themselves these processes are physiological, i.e. normal. The pathological reflux of stomach contents into the esophagus is called gastroesophageal reflux, and the mechanism that prevents vomiting is called the antireflux mechanism.

Anti-reflux mechanism in children

In children, the nervous regulation of the antireflux mechanism is very complex and easily disturbed under the influence of external and internal factors. Regurgitation and vomiting easily occur in children with an immature antireflux mechanism, if the mode or volume of feeding is incorrectly selected, as a reaction to artificial mixtures, at the slightest sign of infectious processes. This is especially often observed in children with intrauterine growth retardation and premature babies, as well as in severe pregnancy and toxicosis, caesarean section, complicated childbirth, etc.

When to see a doctor

Despite the fact that moderate regurgitation in a child under 6 months is considered a variant of the norm, parents should definitely tell the pediatrician about this during a routine examination. The reason for serious concern and immediate examination of the child is an increase in the frequency or increase in the volume of regurgitation, the appearance of streaks of blood or bile impurities, a lag in recruitment or weight loss, and high temperature. In this case, it is urgent to consult a surgeon to rule out surgical causes.

Diagnostics

In most cases, an ultrasound examination (ultrasound) is necessary to establish an accurate diagnosis and select the correct treatment. An experienced doctor of ultrasound diagnostics helps to establish the correct diagnosis in more than half of the cases. Sometimes, for a more accurate diagnosis, a flexible gastroscopy, X-ray examination, or computed tomography of the abdominal organs is performed.

When surgery is required

Pyloric stenosis, or impaired patency of the gastric outlet, is the cause of the most severe regurgitation syndrome (vomiting "fountain") in children under 2 months, accompanied by severe weight loss and progressive deterioration of the child's condition. This disease requires urgent surgical care. In leading clinics, such operations are performed using a minimally invasive laparoscopic method. The current level of development of surgery and pediatric anesthesiology allows the use of endoscopic surgery techniques even in children in the first weeks of life.

There are also other causes of regurgitation that require surgical intervention, such as hiatal hernia, chalazia (gape) of the esophagus, and others. These malformations are characterized by a violation of the formation of the antireflux mechanism and lead to constant regurgitation in a child, impaired weight gain, decreased appetite, chronic cough, bronchial asthma, and anemia. If drug therapy is ineffective, then a gastrofundoplication operation is indicated, in which an artificial antireflux valve is surgically formed. Like many other interventions, in modern children's clinics this operation is performed laparoscopically - with less trauma, minimal blood loss, minimal cosmetic defect and a quick recovery of the child after the operation.

Of course, vomiting and regurgitation can be symptoms of many other diseases and occur at any age in a child. Thus, vomiting is often observed in acute appendicitis and intestinal obstruction, it can be a symptom of an intestinal infection, intoxication, etc. In addition to the disease itself, vomiting and profuse regurgitation are dangerous because the child loses a large amount of water and salts necessary for life, which can lead to dehydration - exsicosis. The younger the child, the faster the disruption of compensatory mechanisms and the worsening of his condition. Therefore, the appearance in a child of symptoms of vomiting or severe regurgitation in young children requires immediate medical attention to identify the causes, establish the correct diagnosis and select the optimal treatment, and, if necessary, surgical.

EMC Children's Clinic is staffed around the clock by experienced pediatricians and surgeons who provide emergency and planned care to children of all ages, starting from the first days of life.

If surgical treatment is required, the method of choice in our clinic is minimally invasive endoscopic surgery, which in most cases allows the child to go home on the day of the operation.
