There may be several causes for vomiting in babies, ranging from indigestion and excessive crying to gastrointestinal tract anomalies. Although occasional vomiting in babies is not a cause for concern, persistent, severe vomiting requires immediate medical attention. This is important to detect and treat the underlying cause and avoid dehydration in babies.

Read on to learn more about the possible causes and home remedies treatment options for vomiting in babies and when to contact a pediatrician.

Common Causes Of Vomiting In Babies

Babies may vomit or experience regurgitation due to various reasons. These include (1):

1. Reflux

A baby’s esophagusⁱXMuscular tube that passes food and liquid from mouth to stomach. (food pipe) is not yet matured, so milk may back up into the food pipe after feeding. This may cause milk to come out from the baby’s mouth or nose. The process of bringing up or gastroesophageal reflux after breastfeeding or bottle feeding is called spitting up, or possetingⁱXBabies bringing up a small amount of milk after a feed without forceful stomach contractions. (2). The condition normally gets better with time and especially when solids are introduced in the diet. Reflux usually clears up within 18 months as the baby grows.

2. Stomach flu

Stomach flu, also called viral gastroenteritis, stomach bug, or tummy bug, is a viral infection of the stomach. In addition, digestive issues like vomiting, diarrhea, fever, and tummy pain are some symptoms of tummy bugs. Babies may have vomiting for a couple of days in the case of stomach flu.

3. Infections

Vomiting and diarrhea can be seen in many other gastrointestinal or organ system infections since the immune system is fighting against it. Urinary tract infections (UTI) and chest infections are common infectious causes of vomiting in babies.

Quick fact

Middle ear infections, pneumonia, and meningitis can also lead to vomiting in babies (1).

4. Food allergies

Allergies or intoleranceⁱXUnpleasant digestive symptoms after consuming certain foods or drinks without involving immune responses. to food may cause vomiting in babies along with cramps and diarrhea. Other symptoms indicative of allergies include skin rashes, such as hives with swelling and itchiness, itching or swelling of the lips, tongue, or mouth, and breathing problems (3). Maternal dietary factors can be a cause of allergies in breastfed babies. Common allergens include milk, eggs, nuts, fish, seeds, and wheat. Allergic reactions and symptoms, such as vomiting, may develop from minutes to hours after exposure to allergens. Milk intolerance, which is lactose intolerance (inability to digest lactose sugar in milk due to lack of lactase enzyme), is different from milk allergy (the body’s immune system reacts to milk proteins). The latter is more common in babies (4).

5. Food poisoning

It may happen in bottle-fed or weaning babies. Unsterilized bottles, stale food, and food or water contaminated with SalmonellaⁱXBacteria that affect the intestinal tract, leading to foodborne illnesses.  or E. coli bacteria could cause food poisoning, leading to vomiting and diarrhea.

6. Poisoning

Babies who crawl or walk may accidentally swallow poisonous substances, which could cause vomiting. You can avoid this by keeping toxic and dangerous chemicals and substances out of the baby’s reach.

7. Overfeeding or overeating

Breastfed or bottle-fed babies may vomit if they are overfed. Large holes in the feeding bottles can be a reason for overfeeding in most bottle-fed babies. Overfeeding a weaning baby could also lead to vomiting.

8. Congenital pyloric stenosis

Congenital pyloric stenosis is the narrowing of the pylorus (part of the stomach connecting to the intestine) from birth. This condition prevents food from entering the intestines from the stomach and causes forceful vomiting. Pyloric stenosis may also cause nutritional deficiencies. The condition is normally not visible at birth but slowly develops over time and symptoms get worse by four to six weeks. Babies are very hungry but vomit projectile shortly after the feed.

Jessica, a mom, talks about her experience with her baby boy’s pyloric stenosis. She says, “Sam had large vomiting episodes when he was amount three and a half weeks old. Then, after feeding him that day, he threw up all over me. He was convulsing, with curdled breastmilk gushing out of his mouth until my clothes were soaked. When it happened again three days later, we called our clinic and talked to the doctor on call. We described the vomiting as ‘projectile’ because it was forceful and traveled a few inches from his mouth, and we said it was at least two to three ounces. My husband A. had read about pyloric stenosis and was concerned that he might have it.”
Later on, after subsequent visits to the doctor and checkups, baby Sam was diagnosed and treated for pyloric stenosis (i).

9. Strangulated hernia

During hernia, intestines push out from the abdominal cavity through the weakened area of the abdominal muscle. A strangulated hernia is a condition where the blood supply to the herniated section of the intestine is cut off. Vomiting, incessant crying due to pain,and diapers with blood (blood in stools) may indicate strangulated hernia, and it requires emergency medical care.

10. Intussusception

Intussusception or telescoping of the intestine is a condition when one segment of the intestine folds into another. Although it can happen anywhere in the intestine, telescoping is common at the ileocecal junction, where the small intestine and large intestine are connected. Severe vomiting, paleness, dehydration, and floppy (hypotonic) look are common symptoms. You may also notice red jelly-like stools in babies. According to the US National Institutes of Health (NIH), 90% of pediatric intussusception cases arise from unknown causes.

Babies with infections tend to have vomiting with fever. However, structural and functional anomalies, such as reflux and pyloric stenosis, may not always cause fever. Therefore, fever cannot be considered a primary symptom to assess the severity of vomiting or a factor to determine the need for medical care.

When To See A Doctor

If the baby is less than three months old, then see a doctor soon after the first signs of vomiting. Although occasional vomiting is normal, babies who are sick, dehydrated, or have frequent vomiting should be taken to a doctor.

You may seek immediate medical care in the following situations (5),(6).

• Vomiting that lasts more than a day or frequent vomiting can indicate infections or structural anomalies.

• Projectile (forceful) vomiting may indicate pyloric stenosis in the babies.

• Greenish-yellow or green color vomit can be due to intestinal obstruction (blockage).

• Blood or coffee-ground appearance of vomiting can indicate bleeding in the GI tract. If you notice blood in a breastfed baby’s vomit, ensure there are no cracks or bleeding in nipples since babies may swallow the blood while feeding.

• Blood in diapers can be an indication of infection or allergy since it may cause blood in stools.

• Diarrhea or constipation may also indicate GI problems in babies.

• Refusing to eat or consume breast milk for a few hours.

• Signs of dehydration, such as sunken eyes, dry mouth, and crying without tears.

• Swollen belly or the abdomen seems painful to touch.

• Dark urine or the baby does not pass urine.

• Fussy and crying for a long time or having a high fever.

• A stiff neck with or without photophobia (discomfort when under bright lights).

Babies may become dehydrated from continuous vomiting. They may also accidentally inhale the vomit, which can increase the risk of aspiration pneumonia.

Caution

Contact your healthcare provider if your infant has had a head injury and vomits anytime in about a week after a head injury (7).

Home Remedies For Baby Vomiting

The main aim of home treatments is to prevent dehydration due to water and electrolyte loss through vomiting. You may try home remedies for baby vomiting after discussing it with a pediatric gastroenterology specialist. They may recommend home care based on your baby’s weight, age, and symptoms.

The home care to prevent dehydration may include:

• Breastfeed babies need to be fed more often, and you may return to a normal feeding schedule once the vomiting is stopped.

• Formula-fed babies need an oral rehydration solution (ORS) every 15 minutes for two to three hours. While you can purchase the over-the-counter ORS, consult the healthcare provider for the dosage so as to not negatively impact infant health. It may vary depending on the baby’s weight, diet, and severity of vomiting.

• Weaning infants can be gradually put backto solid foods as vomiting lessens.

When To Feed The Baby After Vomiting?

The following tips may help you decide when to feed and not feed your baby after vomiting.

• You may offer breastfeeding or bottle feeding after throwing up. If your baby is ready to eat, you may feed them right away.

• Give a small amount of breast milk or fluids after vomiting and observe if they are vomiting again.

After vomiting, feeding breast milk or liquids may help settle down nausea in babies and ease the throat irritation.You may offer water with a spoon or in a bottle to babies older than six months.

• If the baby resists feeding after vomiting, wait for a while before trying again.

If the baby has earache or fever, you may give pain medication such as acetaminophen after consulting the pediatrician. The medication can relieve symptoms before feeding again. If your baby has severe vomiting and refuses to feed, seek help from a pediatrician. Not feeding after vomiting could increase the risk of dehydration.

Treatment For Vomiting In Babies

Pediatricians examine the baby and ask about the signs and symptoms before beginning the treatment. If your baby has normal vomiting without any concerning cause, they may not prescribe medications.

Depending on the cause, the following treatment options are recommended (7).

• Oral rehydration solution can be given to babies who can drink without vomiting again.

• Babies with severe dehydration and those who refuse oral intake of fluids may require intravenous (IV) fluids and electrolytes.

• Antibiotics are prescribed for bacterial infection

• Viral gastroenteritisⁱXThe irritation or inflammation of the stomach and intestines. and other viral infections are usually treated with fluids and other supportive therapies.

• Structural anomalies and conditions may require surgical correction to cure the vomiting.

Note: Medications (antiemetics) to stop vomiting are not given to children younger than two years due to their potential side effects.
