Why Newborns Throw Up: Common Causes of Vomiting in Newborns

There are several facts related to newborns and doing vomiting is one of them. There are several why newborns vomit and some of them are mentioned below: 

1. Tummy Bug

Viruses are common causes of vomiting in babies due to their developing immune systems. Viral vomiting typically starts suddenly, improves within 1-2 days, and may include symptoms like diarrhea, fever, or stomach pain. Most viral cases resolve on their own with home care.

However, it’s important to consult your doctor if your baby shows signs of dehydration, if symptoms worsen or persist beyond a few days, or if vomiting occurs without diarrhea, especially in very young infants. 

2. Too Much Milk

Newborns can’t control how much they eat. They keep drinking even when full. Their stomachs are tiny, about the size of a cherry. When they drink too much, the extra milk has to come out. This is why babies often spit up after feeding. It’s normal but messy.

3. Swallowed Air

Babies often swallow air while feeding, both with bottles and breastfeeding. The air fills up space in their tummies, and when it comes up, it often brings milk with it. Burping your baby during and after feeds can help, but some babies still spit up even with burping.

4. Food Poisoning

This is another reason why newborns vomit. If your baby drinks or eats something that has bacteria in it, it can result in an upset tummy. In formula-fed babies, this generally happens due to dirty bottles or nipples.

If your baby has begun solids, it can happen due to various factors related to their new diet. Contaminated food from improper storage or preparation can introduce harmful bacteria, while introducing new foods may trigger allergic reactions or food intolerances in some babies. Food poisoning in babies resembles a viral infection, with symptoms including fever, diarrhea, abdominal discomfort, and vomiting.

5. Reflux

Has your child ever suddenly started vomiting everything they eat or drink? Babies often have this tummy issue called acid reflux. It happens when the food they’ve swallowed comes back up. Sometimes, this means the baby throws up.

Other times, they might just spit up a little in their mouth. This problem is super common in little ones. Why? Well, babies drink all their food – they’re on an all-liquid diet. Plus, they spend most of their time lying down. These two things make it easier for food to travel the wrong way. So, if your baby spits up often, don’t worry too much. It’s usually just their tiny tummy getting used to the world.

6. Milk Allergy

A few babies can’t handle proteins in milk. This includes cow’s milk and sometimes breast milk. Their bodies treat these proteins like invaders. They react by throwing up. This is rare but needs a doctor’s help. The doctor might suggest changing the formula or mom’s diet.

7. Pyloric Stenosis

Pyloric Stenosis is a severe problem. It happens when the path from the stomach to the gut gets too narrow. Food can’t pass through. Babies throw up forcefully, often in an arc. They can’t keep any food down. This makes them very sick very fast. It needs surgery to fix. If your baby has robust and projectile vomiting, call the doctor right away.

Remember, a little spit-up after feeding is normal. However, if your baby throws up a lot, seems in pain, or isn’t gaining weight, don’t hesitate to call your doctor. They can check if there’s a problem and help fix it. Your proactive approach can make a significant difference in your baby’s health and well-being.

What’s Normal When It Comes to Newborns’ Milk Vomit? 

Here are some key points about what’s normal when it comes to newborns’ milk vomit:

1. Weight Gain

This is generally a good sign if your newborn is gaining weight appropriately. Newborns should regain their birth weight by 2 weeks of age and then continue to gain about 4-7 ounces per week. As long as your baby is steadily gaining, the occasional spitting up or vomiting is likely normal.

2. Eating Well

If your newborn is feeding well, taking in adequate amounts of milk at each feeding, and showing signs of hunger and satiety, you can consider it normal.  Questions to consider:

• How many wet/dirty diapers does your baby have per day?
• How long and how often is your baby feeding?
• Is your baby content and satisfied after feedings, or do they seem frustrated or unsatisfied?

Not Losing Excessive Weight

As long as your newborn is not losing more than 10% of their birth weight, the vomiting is likely not causing excessive weight loss. Steady weight gain is the key indicator. Questions to consider:

• How much has your baby’s weight changed since birth?
• Are you tracking their weight gain on a growth chart?

Not Lethargic

If your newborn is active, alert, and showing appropriate energy levels during awake time, this is a good sign that the vomiting is not causing significant distress or dehydration. Questions to consider:

• What is your baby’s activity level and responsiveness?
• Does your baby seem overly sleepy or difficult to wake?

What’s the Difference Between Vomiting and Reflux?

Vomiting and reflux in babies are distinct conditions, though they can sometimes be confused:

Vomiting:

• Forceful expulsion of stomach contents
• Often projectile in nature
• Usually, larger amounts of liquid
• Other symptoms like fever or illness may accompany it
• Less frequent, often linked to specific causes (illness, food intolerance)

Reflux:

• Gentle regurgitation of stomach contents
• Also known as “spitting up.”
• Typically, smaller amounts of liquid
• Often occurs during or shortly after feeding
• More frequent and considered normal in most infants
• Usually, it doesn’t cause discomfort for the baby

Reflux is generally harmless and common in babies as their digestive systems mature. Vomiting, especially if frequent or accompanied by other symptoms, may indicate a more serious issue and should be evaluated by a healthcare provider. 

When to Say that Spitting is a Sign of Danger

While vomiting is common in newborns, certain signs might show an underlying condition. Here are some key symptoms that you shouldn’t ignore:

• Lack of weight gain
• Forceful spitting up
• Spitting up green or yellow fluid
• Spitting up blood or a material that resembles coffee grounds
• Repeatedly refusing feedings
• Blood in the stool
• Difficulty breathing or other signs of illness
• Onset of spitting up at 6 months of age or older
• Crying for more than 3 hours per day and increased irritability
• Fewer wet diapers than normal

The treatment for newborn vomiting depends on the cause. Special feeding strategies might be helpful; in other cases, the doctor might prescribe medication to treat reflux.

How to Deal with Vomiting in Newborns? 

Now, you know why newborns vomit and what are the alarming signs, let’s have a look at some of the cures. 

1. Managing Newborn Vomiting

Giving your baby smaller, more frequent meals can help prevent their tiny stomach from becoming overwhelmed. Instead of larger, infrequent feedings, try offering your newborn smaller portions at shorter intervals. This allows their body to comfortably process the milk without triggering vomiting.

2. Burping Technique 

Burping your baby during and after feedings can help release any trapped air contributing to their vomiting. Gently pat or rub your baby’s back until you hear a satisfying burp, even if it takes some time. Getting that air out can make a big difference in keeping their milk down.

3. Upright Positioning 

After feeding your newborn, keeping them upright for around 30 minutes is essential. This allows gravity to help the milk stay where it should be rather than coming back up. The same principle applies to babies, much like how we don’t feel great lying down immediately after a large meal.

4. Switching Formula 

If your baby has trouble tolerating their current formula, switching to a different type may provide relief. Just like people have individual preferences and tolerances, a simple formula change can sometimes solve persistent vomiting.

5. Surgical Intervention 

A minor surgical procedure may be necessary in more severe cases, such as pyloric stenosis. This involves a small adjustment to open up the pathway from the stomach to the intestines, allowing food to flow properly and alleviating the vomiting. While it may sound daunting, this type of surgery is commonly performed and can provide lasting relief.

The key is working closely with your pediatrician to identify the underlying cause and implement the appropriate management strategies for your newborn. You can help soothe their discomfort and get them back to happy, healthy feeding with the right approach.

Final Thoughts

Newborn milk vomit is quite common in most cases. So, there is usually no need for an immediate alarm. However, it’s crucial for parents to distinguish between normal spit-up and problematic vomiting. While occasional spit-up is typically harmless, persistent or forceful vomiting, especially when accompanied by other symptoms, warrants medical attention. 

By implementing simple strategies like adjusting feeding practices and positioning, most issues can be alleviated. Remember, every baby is unique, and when in doubt, consulting with a pediatrician is always the best course of action to ensure your newborn’s health and peace of mind.
