Newborn Grunting: Normal Or Cause For Concern?

It is perfectly normal for newborns to make grunting noises. In fact, babies make all sorts of sounds, from grunting and gurgling to squeaking and snoring. While it may sound like your newborn is in pain, they are usually just learning how to pass stool. Newborns tend to grunt as they get used to having bowel movements, and doctors sometimes refer to this as grunting baby syndrome. However, newborn grunting can occasionally indicate a health issue, such as trapped mucus, gastroesophageal reflux, or irregular breathing. If your baby is grunting with every breath, has a fever, or appears to be in distress, seek medical attention.

Newborn grunting is usually related to digestion

To pass a stool, an adult will relax their pelvic floor and use their stomach muscles to apply pressure, which helps move the stool through the gut. Newborns, however, don't yet have strong enough stomach muscles to do this, so they use their diaphragm to move their bowel. As they exercise their diaphragm, it can put pressure on the voice box, resulting in grunting.

Babies are not yet adept at relaxing their pelvic floor or using their tummy muscles to help move their bowels quietly. This results in noisy grunting and straining when they have a bowel movement. Although this can sound like they are in pain, it is not usually true.

Grunting related to digestion can also be caused by acid reflux, which occurs when the muscle between the stomach and oesophagus doesn't remain closed properly, allowing stomach contents to rise into the food pipe. This can cause discomfort, and the baby may grunt.

If your baby is grunting and has a fever, vomiting, blood in their stool or diaper, or a bloated belly, seek medical attention as soon as possible.

Grunting may be a sign of respiratory distress

While newborn grunting is usually related to digestion, it can sometimes be a sign of respiratory distress. Grunting with every breath is never normal and could be a sign of respiratory distress. Other signs to look out for include flared nostrils, an extra-long exhale sound, and a whistling sound each time your baby breathes out. These symptoms could indicate respiratory syncytial virus (RSV), bronchiolitis, or respiratory distress syndrome.

Respiratory distress in newborns is a common issue, affecting up to 7% of all term newborns. It is often caused by tachypnea, a respiratory rate of more than 60 breaths per minute. Other signs of respiratory distress include nasal flaring, chest retractions, and cyanosis. It is important to monitor your newborn's vital signs and seek medical attention if you are concerned.

If your baby is grunting and also has other signs of illness, such as a fever, or appears to be in distress, it is important to see a doctor. This could be a sign of a serious medical condition such as heart failure, which causes fluid to build up in the lungs and can lead to shortness of breath.

In summary, while newborn grunting is usually related to digestion, it is important to be aware of the signs of respiratory distress. If you are concerned about your baby's grunting, it is always best to seek medical advice.

Grunting can be caused by acid reflux

It's perfectly normal for newborns to make grunting noises, and it usually means they are learning how to pass stool. However, newborn grunting can sometimes indicate a health issue, such as gastroesophageal reflux (GER), also known as acid reflux.

Acid reflux occurs when the contents of the stomach back up into the oesophagus, which is the tube that carries food from the throat to the stomach. At the bottom of the oesophagus is a ring of muscle called the lower oesophageal sphincter (LES) that normally opens when you swallow. When the LES doesn't close completely, stomach contents and digestive juices can come back up into the oesophagus, causing discomfort.

Acid reflux is common in infants due to their LES being weak or underdeveloped. It is estimated that more than half of all infants experience acid reflux to some degree. The condition usually peaks at age 4 months and goes away on its own between 12 and 18 months of age. If symptoms persist past 24 months, it may indicate a more severe condition called gastroesophageal reflux disease (GERD).

• Spitting up and vomiting: While spitting up is normal for infants, forceful spit-up or vomiting may be a symptom of GERD, especially if your infant is older than 12 months. Spitting up blood, green or yellow fluid, or a substance that looks like coffee grounds may also be a cause for concern.
• Refusal to eat and difficulty eating or swallowing: Your infant may refuse to eat if they experience pain during feeding due to irritation from stomach contents coming back up into their oesophagus.
• Irritability during feeding: Infants with GERD may scream and cry during feeding due to abdominal discomfort or oesophageal irritation.
• Wet burps or hiccups: A wet burp or hiccup is when an infant spits up liquid when they burp or hiccup, which can be a symptom of acid reflux or GERD.
• Failure to gain weight: Weight loss or failure to gain weight may occur due to excessive vomiting or poor feeding associated with acid reflux or GERD.
• Frequent coughing or recurrent pneumonia: Acid or food coming up into the back of the throat can cause frequent coughing. Inhaled regurgitated food can also lead to chemical or bacterial pneumonia.
• Gagging or choking: Your baby may gag or choke when stomach contents flow back into their oesophagus, especially if they are not kept in an upright position for at least 30 minutes after feeding.
• Chest pain or heartburn: Regurgitated stomach contents can irritate the oesophageal lining and cause heartburn, although this may be hard to recognise in infants.

If you suspect your newborn is experiencing acid reflux or GERD, it is important to speak with your baby's doctor or pediatrician. They can rule out other conditions, confirm a diagnosis, and suggest lifestyle changes or treatments to help manage the condition.

Grunting can be a result of trapped mucus

It's perfectly normal for newborns to make grunting noises, and it usually means they are learning how to pass stool. However, trapped mucus can also be the reason behind your newborn's grunting.

Newborns have tiny noses and nasal passages, and it is easy for their narrow nasal passages to get blocked. Their respiratory systems are still developing, and they are nose breathers for the first few months of their lives. This means that even a small amount of mucus, breast milk, or formula can migrate to the back of their nasal passages, causing congestion and sleep noises.

Trapped mucus can also be a sign of a cold or flu, or, in rare cases, a more serious illness such as cystic fibrosis. If your newborn is grunting due to trapped mucus, you can help them clear their nasal passages by:

• Wiping their nose
• Using a nasal aspirator
• Using a saline nasal rinse made for babies
• Using a clean bulb syringe to suction out the mucus
• Using a saline spray to help loosen dried mucus and clear out the nostrils
• Using a cool-mist humidifier in the baby's room to keep the air moist
• Giving your baby a warm bath to help them breathe in steam
• Feeding your baby regularly to keep them hydrated
• Removing potential allergens by vacuuming up dust and pet hairs
• Putting your baby over your knee and gently rubbing their back to help clear mucus

Grunting can be a sign of dreaming

It is perfectly normal for newborns to make grunting noises, especially during sleep. In fact, newborn sleep is far from quiet, and babies make all sorts of noises while sleeping, including grunts, squeaks, snores, gurgles, and squeals.

Grunting in newborns is usually related to digestion. Newborns are still getting used to mother's milk or formula and may have gas or pressure in their stomach that makes them uncomfortable. They are learning how to have a bowel movement and pass gas, and the grunting noise is caused by the pressure on their voice box as they bear down with their diaphragm against their closed voice box (glottis). This is known as Grunting Baby Syndrome (GBS) and is fairly common and rarely a sign of something serious.

While grunting is usually nothing to worry about, if your baby is grunting with every breath, has a fever, or appears to be in distress, it is important to seek medical attention as it could be a sign of a more serious respiratory problem.
