Grunting Baby Syndrome

For a parent of a newborn, things can get a little overwhelming at times. And these parents can be as sensitive as their infants are. Looking at your baby even in the slightest pain can be extremely agonizing. One of the common kinds of pain that a baby suffers from is grunting. A baby may grunt while playing, pooping and even sleeping.

Grunting can be caused due to many reasons but one of the dominant reasons can be the grunting baby syndrome. Even though it is not rare, the grunting baby syndrome still remains a mystery to most new parents. And to add to this confusion is its similarities with constipation. Your baby surely looks uncomfortable while pooping which is when they have grunting baby syndrome, it is because they have to work hard to figure out how to poop.

But the good news is that this discomfort for the baby, and thus for the parents, is short-lived and gets resolved as soon as the babies complete their bowel movement. If you are looking about this condition as a to-be parent or a parent or a caretaker of a newly born baby, you do not have to worry at all. We have got it all covered for you. Read on to learn all about the Grunting Baby Syndrome.

What is Grunting Baby Syndrome

At the first glance, the grunting baby syndrome may seem disguisedly similar to constipation but there is a clear difference between the two. However, if the stool in the baby’s diaper is soft, there are chances that those noises coming from your baby’s stomach are being caused by something else.

If your infant baby grunts, wriths, turns red or shows signs of strain while trying to poop, they might be having a condition named Infant Dyschezia. In a more general language, it is known as grunting baby syndrome (GBS). Quite obviously, seeing your baby turn red or seem to work hard to poop may seem something to be concerned about, it is in fact quite normal and most probably not a cause for concern.

Causes of Grunting Baby Syndrome

Now that you know what the baby grunting syndrome is, it is essential to know what causes your newborn to grunt as they are trying to get used to their bowel movements. In order to pass stool, an adult has to relax their pelvic floor and then use the stomach muscles for applying pressure that eventually helps in moving the stool through the intestines. But the case isn’t exactly the same for a newborn baby. Let us delve into the science of your baby’s body. 

The world-famous paediatrician Dr Harvey Karp in his book, Happiest Baby on the Block, explains that it is difficult to poop as a baby. This is mostly because a baby has to do opposite things — tighten the muscles of the stomach while simultaneously relaxing the anus. It takes a baby’s body some practice to use their abdominal muscles for moving their poop and gas across their system while also relaxing the pelvic floor. While they are still figuring it out, it can cause pain as well as discomfort until your newborn learns the needed coordination.

Causes of Grunting Baby Syndrome

At first, a newborn’s stomach muscles are not strong enough to do this, so the baby ends up using their diaphragm muscle for moving their bowel. It is during this exercise of the diaphragm that can exert pressure on the voice box, resulting ultimately in grunting.

However, this is not the only reason due to which your baby may be grunting. Moreover, some babies even grunt during their sleep. So the other things that may cause newborn grunting to include irregular breathing patterns, trapped mucus, and the gastroesophageal reflux (GER). Babies may grunt when they start to develop control over their breathing patterns or when mucus gets collected in their narrow nasal passages. Gastroesophageal reflux which is otherwise known as acid reflux is also one of the reasons. The food content from the baby’s stomach may rise into the baby’s food pipe causing the discomfort making the baby grunt. The baby grunting during sleeping may also be caused because they are dreaming.

When an infant has constipation, which is actually rare, the newborn passes hard or even pellet-like stool. The baby also experiences infrequent bowel movements. This is starkly different from the grunting baby syndrome. In grunting baby syndrome, the infant still poops regularly and has soft or semi solid poop. If you are afraid that your baby is constipated, we advise you to check with your doctor.

While suffering from constipation, your newly born baby may make grunting noises but not pass stool immediately after the grunting episode. The baby can go three to four days between two bowel movements and have hard, compact stools when they finally poop. Thankfully, GBS is easy to fix once detected. All you need to do is to ensure that the constipation is caused due to general reasons like dehydration or unsuitable baby feeding formula and not something concerning such as hypothyroidism or the Hirschsprung’s disease. In either case, it is suggested that a doctor is consulted with.
